Abstract
PURPOSE Medical training has undergone many transformations to incorporate diagnostic imaging along side anatomical education. Post-mortem computed tomography (CT) scanning of body donors prior to dissection has been proposed. However, it poses challenges secondary to the embalming process and other post-mortem physiological changes that significantly alter the imaging quality. The purposes of this study were to compare the accuracy of pathology identification on pre- and post-mortem CT scans of body donors and to assess the integration of those scans in a dissection-based course, where these images were overlaid onto body donors using augmented reality (AR). METHODS Participants in this study included 35 fourth year medical students, 5 radiology residents and 3 radiologists. A convergent, parallel mixed methods design was employed with quantitative measures that included statistical analyses of a double-blinded comparison of pathological lesions recognition, on both image sets, the group responses to a study participant survey and the login access data from imaging repository. The study also included qualitative analysis of post-elective structured interviews. RESULTS The double-blinded comparison revealed that staff radiologists can only identify, on post-mortem images, 54.8% of the pathologies that they were able to detect on the pre-mortem scans. Analyses of the surveys and login access data reveal that 60% of radiology residents and 56% of students preferred pre-mortem scans and used those scans more often than post-mortem scans (67 access vs 36, respectively). However, post-mortem scans were significantly preferred when used to overlay onto body donors using AR (p = 0.0047). CONCLUSION These results show that post-mortem imaging can be valuable alongside pre-mortem imaging, as they represent the most concordance between the anatomical structures and pathologies seen on the images and what is being dissected.

Abstract
Augmented reality (AR) has recently been utilized as an integrative teaching tool in medical curricula given its ability to view virtual objects while interacting with the physical environment. The evidence for AR in medical training, however, is limited. For this reason, the purpose of this mixed method study was to evaluate the implementation of overlaying donor-specific diagnostic imaging (DSDI) onto corresponding body donors in a fourth-year, dissection-based, medical elective course entitled anatomy for surgeons (AFS). Students registered in AFS course were separated into groups, receiving either DSDI displayed on Microsoft HoloLens AR head-mounted display (n = 12) or DSDI displayed on iPad (n = 15). To test for the change in spatial ability, students completed an anatomical mental rotation test (AMRT) prior to and following the AFS course. Students also participated in a focus group discussion and completed a survey at the end of AFS, analyzed through thematic triangulation and an unpaired, Mann Whitney U test respectively, both addressing dissection experience, DSDI relevancy to dissection, and use of AR in anatomical education. Although statistically significant differences were not found when comparing student group AMRT scores, survey and discussion data suggest that the HoloLens had improved the students' understanding of, and their spatial orientation of, anatomical relationships. Trunk dissection quality grades were significantly higher with students using the HoloLens. Although students mentioned difficulties with HoloLens software, with faculty assistance, training, and enhanced software development, there is potential for this AR tool to contribute to improved dissection quality and an immersive learning experience.

Implications of introducing case based radiological images in anatomy on teaching, learning and assessment of medical students: a mixed-methods study. BMC MEDICAL EDUCATION 2022; 22:723. [PMID: 36242009 PMCID: PMC9569043 DOI: 10.1186/s12909-022-03784-y] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 05/20/2022] [Accepted: 09/27/2022] [Indexed: 06/16/2023]
Abstract
BACKGROUND Introducing radiological anatomy in the preclinical curriculum can increase the understanding of Anatomy. Regardless of the integration when teaching anatomy, it is essential to maintain oversight as to what and how much is being taught. In addition, the knowledge requirements for preclinical students should be considered. The purpose of this kind of integration is that the student should be able to apply the knowledge which can help them better understand anatomy and not to make the course more challenging. This study aimed to understand whether adding radiological images would increase the difficulty level of the questions. METHODS We introduced radiological images, including X Rays, CT scans and MRIs, when teaching anatomy in the preclinical curriculum. A class of 99 students were tested using A-type MCQs (n = 84). All 84 questions were categorized on whether they were case-based with or without a radiological image. The item analysis of both groups of test questions was then compared based on their difficulty and discrimination index. A qualitative student perception regarding the inclusion of radiological images in anatomy was also measured using a questionnaire with a 5-point Likert scale. RESULTS The results showed that the performance level of the students was similar when comparing the test questions in both groups. The item analysis of the MCQs in the two groups revealed that by integrating radiological images when teaching anatomy, the various parameters in both groups of test questions were in the same range. More than 80% of the students felt that radiological images facilitate the achievement of learning outcomes and help to apply their knowledge in clinical contexts. The study's findings reported that the rate of satisfaction by including radiological images when teaching anatomy is high. CONCLUSION Recognition and interpretation of images are essential in an undergraduate medical program. Students found it helpful when radiological images were introduced to them when teaching anatomy. Since the students' performance in summative exams in both groups of questions was in the same range, the findings also point out that adding radiological images when teaching anatomy does not increase the difficulty of the subject.

Abstract
An in-depth understanding of the anatomy discipline is essential for the work of healthcare professionals. In recent decades, the content and time of teaching anatomy have decreased in all health science degrees. The aim of this study was to look for alternatives for compensating the reduction of the teaching of anatomy by supplementing students with a practical training course and to know evaluations of the course given by students enrolled in the degree in Speech Therapy and its impact on their academic results. All students (100%) positively evaluated having acquired skills and attitudes for their future professional life. The majority of the students (95.8%) believed that their knowledge was acceptable; 97.2% of the students thought they would have the possibility to apply their acquired anatomical knowledge as professionals; 98.5% were satisfied with the voluntary course; and finally, the percentage of students that passed the "Anatomophysiology of language and voice organs" course increased from previous academic years. Optional (theoretical/practical) undergraduate courses can be used in parallel to overcome the devaluation of anatomical studies in new curricula. The optional undergraduate anatomy course in the Speech Therapy program has been positively evaluated because it stimulated students' motivation and appealed to their interest in anatomy. Students considered that these courses would help them in their training and they could put what they had learned into practice in their future professions. However, very little evidence for the impact of optional practical courses exists, yet it could be an efficient method to increase anatomical knowledge.

Abstract
Growing evidence supports the use of reflective writing activities centered around the human cadaveric dissection experience to support and assess elements of medical student wellness. Dissection may promote personal and professional development, increase resilience, and foster a sense of connection and community. This study employed a qualitative analysis of a reflective writing exercise to explore the question: "What is the impact of the cadaveric dissection anatomy experience on the personal and professional development of medical students?" This cross-sectional study was conducted at the conclusion of the first-year anatomy module. A total of 117 United States allopathic medical students were given a questionnaire designed to elicit the students' experiences and introspection. The exercise included four reflective questions that were provided to 20 groups of six students. Grounded theory analysis was used to explore themes that arose in students' responses. Participants exhibited several common reactions to cadaveric dissection. After analyzing all responses, 266 unique open codes were identified for all four questions. These open codes were sorted into ten distinct axial codes, which are broader categorical themes of open codes. The aims of our study were to identify themes that emerged as students reflected on the impact of their dissection experience using reflective writing as a tool to capture these themes and to gather information to inform pedagogical methodologies. The researchers observed that the educational effects of dissection captured in the reflective writing resembled those found in other areas of medical education that emphasize professional identity formation and important humanistic qualities.

Cinematic Rendering in Anatomy: A Crossover Study Comparing a Novel 3D Reconstruction Technique to Conventional Computed Tomography. ANATOMICAL SCIENCES EDUCATION 2021; 14:22-31. [PMID: 32521121 DOI: 10.1002/ase.1989] [Citation(s) in RCA: 19] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/30/2019] [Revised: 06/02/2020] [Accepted: 06/02/2020] [Indexed: 06/11/2023]
Abstract
Integration of medical imaging into preclinical anatomy courses is already underway in many medical schools. However, interpretation of two-dimensional grayscale images is difficult and conventional volume rendering techniques provide only images of limited quality. In this regard, a more photorealistic visualization provided by Cinematic Rendering (CR) may be more suitable for anatomical education. A randomized, two-period crossover study was conducted from July to December 2018, at the University Hospital of Erlangen, Germany to compare CR and conventional computed tomography (CT) imaging for speed and comprehension of anatomy. Sixteen students were randomized into two assessment sequences. During each assessment period, participants had to answer 15 anatomy-related questions that were divided into three categories: parenchymal, musculoskeletal, and vascular anatomy. After a washout period of 14 days, assessments were crossed over to the respective second reconstruction technique. The mean interperiod differences for the time to answer differed significantly between the CR-CT sequence (-204.21 ± 156.0 seconds) and the CT-CR sequence (243.33 ± 113.83 seconds; P < 0.001). Overall time reduction by CR was 65.56%. Cinematic Rendering visualization of musculoskeletal and vascular anatomy was higher rated compared to CT visualization (P < 0.001 and P = 0.003), whereas CT visualization of parenchymal anatomy received a higher scoring than CR visualization (P < 0.001). No carryover effects were observed. A questionnaire revealed that students consider CR to be beneficial for medical education. These results suggest that CR has a potential to enhance knowledge acquisition and transfer from medical imaging data in medical education.

Abstract
BACKGROUND Medical faculties are currently embracing a modernistic approach to anatomical education that integrates diagnostic imaging largely through post-mortem computed tomography scanning of body donors. Post-mortem imaging, however, poses a multitude of challenges. The purpose of this study was to assess the implementation of pre-mortem donor-specific diagnostic imaging on student learning and dissection experience in addition to understanding the potential impact on students' preparation for clinical practice. METHODS Students in a fourth-year medicine elective course were divided into groups; group 1 received pre-mortem donor-specific diagnostic imaging, while group 2 received pathology-specific diagnostic imaging, a collection of images relating to the type(s) of pathologies the donors exhibited, though not specific to the donors themselves. Both groups also received a donor-specific case vignette. A convergent, parallel mixed methods design was employed. This included integrating data from group responses to a study participant survey and students' academic assessment scores analyzed quantitatively through statistical analyses with data from focus group sessions investigating the psychosocial aspects of the student dissection experience and perceptions of the imaging use in the course analyzed qualitatively. RESULTS As compared to students receiving pathology-specific diagnostic imaging, the quantitative results demonstrated that students receiving pre-mortem donor-specific diagnostic imaging more positively supported the relevancy of diagnostic imaging to their understanding of anatomy, valued the integration for future practice, and suggested an earlier integration within their medical curriculum. Qualitatively, two main themes were observed: the influence of diagnostic imaging integration on dissection experience and on professional mindset. Although both student groups received imaging corresponding to their body donor, consideration towards the humanistic nature of the body donor as a patient with a history was limited to student feedback from the donor- specific diagnostic imaging group. CONCLUSION Overall the integration of pre-mortem donor-specific diagnostic imaging into anatomical dissection provided students with practical skill development, an enhanced dissection experience, and reinforced personal qualities critical for future practice.

Abstract
This study was performed primarily to clarify whether pathological analysis of cadavers for anatomical dissection is possible using postmortem imaging (PMI), and whether this is worthwhile. A total of 33 cadavers that underwent systematic anatomical dissection at our medical school also underwent PMI. Fixative solution was injected into the corpus 3-4 days after death. PMI was then performed using an 8-slice multi-detector CT scanner 3 months before dissection. Before dissection, a conference was held to discuss the findings of the PMI. First, two radiologists read the postmortem images without any medical information and deduced the immediate cause of death. Then, the anatomy instructor revealed the medical information available. Based on this information, the radiologist, anatomy instructor, and pathologists suggested candidate sampling sites for pathological examination. On the last day of the dissection period, the pathologists resected the sample tissues and processed them for pathological examination. In 12 of 33 cases, the presumed causes of death could be determined based on PMI alone, and revision of the cause of death described in the death certificate was considered in five (15.2%) cases, based on PMI and pathological analysis. This article presents a novel method of pathological analysis of cadavers for anatomical dissection using PMI without disturbing the anatomy education of medical students.

Abstract
With the development of cross-sectional imaging techniques and transformation to digital reading of radiological imaging, e-learning might be a promising tool in undergraduate radiology education. In this systematic review of the literature, we evaluate the emergence of image interaction possibilities in radiology e-learning programs and evidence for effects of radiology e-learning on learning outcomes and perspectives of medical students and teachers. A systematic search in PubMed, EMBASE, Cochrane, ERIC, and PsycInfo was performed. Articles were screened by two authors and included when they concerned the evaluation of radiological e-learning tools for undergraduate medical students. Nineteen articles were included. Seven studies evaluated e-learning programs with image interaction possibilities. Students perceived e-learning with image interaction possibilities to be a useful addition to learning with hard copy images and to be effective for learning 3D anatomy. Both e-learning programs with and without image interaction possibilities were found to improve radiological knowledge and skills. In general, students found e-learning programs easy to use, rated image quality high, and found the difficulty level of the courses appropriate. Furthermore, they felt that their knowledge and understanding of radiology improved by using e-learning. In conclusion, the addition of radiology e-learning in undergraduate medical education can improve radiological knowledge and image interpretation skills. Differences between the effect of e-learning with and without image interpretation possibilities on learning outcomes are unknown and should be subject to future research.

Abstract
Anatomy teaching, once thought of as being the cornerstone of medical education, has undergone much change in the recent years. There is now growing concern for falling standards in medical graduates' anatomical knowledge, coupled with a reduction in teaching time and appropriately qualified teaching staff. With limited contact hours available to teach this important discipline, it is essential to consider what anatomy is taught within the medical curriculum to ensure it is fit for clinical practice. The views of medical students, junior doctors, and consultants were obtained from the University of Nottingham and the Trent Deanery in Nottingham, United Kingdom, to establish what core anatomical knowledge they feel medical students should study and assimilate during preclinical training. All participants felt strongly that medical students should be adept at interpreting modern diagnostic images before entering their clinical placement or specialty. Respondents proposed more teaching emphasis should be placed on specific anatomical areas (including lymphatic drainage and dermatome innervation) and illustrated other areas where less detailed teaching was appropriate. Recommendations from our study highlight a need for greater clinical emphasis in anatomy teaching during preclinical years. To successfully achieve this, it is essential that clinicians become integrally involved in the design and delivery of future medical undergraduate anatomy courses.

Abstract
BACKGROUND Anatomy educators are increasing their utilisation of radiology in anatomy education in line with growing requirements for undergraduate radiology competency and clinical need. AIMS We aimed to evaluate student perceptions of radiology and to outline the technical and academic considerations underlying the integration of radiology into musculoskeletal practical anatomy sessions. MATERIALS AND METHODS The formal integration of radiology into anatomy practical sessions took place over a 5-week period during the lower limb musculoskeletal component of the anatomy course taught to first-year medical students. During practical sessions, students were required to rotate between aligned audio-visual radiology presentations, osteology/anatomical models, and prosection/dissection learning stations. After completing the course, students were invited to complete a survey to establish their opinions on radiology as a mode of learning and their satisfaction with radiological integration in anatomical practical sessions. RESULTS Most students were not familiar with radiology prior to attending our university. All our students agreed or strongly agreed that learning to read radiographs in anatomy is important and most agreed that radiology is a valid assessment tool. Sixty percent stated that radiology facilitated their understanding of anatomy. The majority believed that radiology was best suited to clinically relevant anatomy and X-rays were their preferred learning tool. CONCLUSIONS The practical approach to integrating radiology into undergraduate musculoskeletal anatomy described here did not place strain on existing academic resources. Most students agreed that radiology should be increased in anatomy education and that learning to understand radiographs in anatomy was important for clinical practice.

Abstract
The use of radiology in the teaching of anatomy to medical students is gaining in popularity; however, there is wide variation in how and when radiology is introduced into the curriculum. The authors sought to investigate students' perceptions regarding methods used to depict and teach anatomy and effects of integrated radiology instruction on students' abilities to correctly identify imaging modalities and anatomical structures on radiological images. First-year medical students completed questionnaires at the beginning and end of the first academic year that incorporated ten hours of radiologic anatomy teaching in the anatomy curriculum. Questions used a combination of Likert scales, rankings, and binary options. Students were tested on their ability to identify radiology modalities and anatomical structures on radiology images. Preresponse and postresponse rates were 93% (157/168) and 85% (136/160), respectively. Postmodule, 96.3% of students wanted the same or more radiology integration. Furthermore, 92.4% premodule and 96.2% postmodule agreed that "Radiology is important in medical undergraduate teaching." Modality and structure identification scores significantly increased from 59.8% to 64.3% (P < 0.001) and from 47.4% to 71.2% (P < 0.001), respectively. The top three preferred teaching formats premodule and postmodule were (1) anatomy laboratory instruction, (2) interactive sessions combining radiology with anatomy, and (3) anatomy lectures. Postmodule, 38.3% of students were comfortable reviewing radiology images. Students were positive about integrating radiology into anatomy teaching and most students wanted at least the same level of assimilation but that it is used as an adjunct rather than primary method of teaching anatomy.

Abstract
PROBLEM We have found it very challenging to integrate images from our radiology digital imaging repository into the curriculum of our local medical school. Thus, it has been difficult to convey important knowledge related to viewing and interpreting diagnostic radiology images. We sought to determine if we could create a solution for this problem and evaluate whether students exposed to this solution were able to learn imaging concepts pertinent to medical practice. INTERVENTION We developed University of Saskatchewan Radiology Courseware (USRC), a novel interactive web application that enables preclinical medical students to acquire image interpretation skills fundamental to clinical practice. This web application reformats content stored in Medical Imaging Resource Center teaching cases for BlackBoard Learn™, a popular learning management system. We have deployed this solution for 2 successive years in a 1st-year basic sciences medical school course at the College of Medicine, University of Saskatchewan. The "courseware" content covers both normal anatomy and common clinical pathologies in five distinct modules. We created two cohorts of learners consisting of an intervention cohort of students who had used USRC for their 1st academic year, whereas the nonintervention cohort was students who had not been exposed to this learning opportunity. CONTEXT To assess the learning experience of the users we designed an online questionnaire and image review quiz delivered to both of the student groups. OUTCOME Comparisons between the groups revealed statistically significant differences in both confidence with image interpretation and the ability to answer knowledge-based questions. Students were satisfied with the overall usability, functions, and capabilities of USRC. LESSONS LEARNED USRC is an innovative technology that provides integration between Medical Imaging Resource Center, a teaching solution used in radiology, and a Learning Management System.

Abstract
Background There is a need for innovative anatomic teaching tools. This paper describes a three dimensional (3D) tool employing the Microsoft Kinect™. Using this instrument, 3D temporal bone anatomy can be manipulated with the use of hand gestures, in the absence of mouse or keyboard. Methods CT Temporal bone data is imported into an image processing program and segmented. This information is then exported in polygonal mesh format to an in-house designed 3D graphics engine with an integrated Microsoft Kinect™. Motion in the virtual environment is controlled by tracking hand position relative to the user’s left shoulder. Results The tool successfully tracked scene depth and user joint locations. This permitted gesture-based control over the entire 3D environment. Stereoscopy was deemed appropriate with significant object projection, while still maintaining the operator’s ability to resolve image details. Specific anatomical structures can be selected from within the larger virtual environment. These structures can be extracted and rotated at the discretion of the user. Voice command employing the Kinect’s™ intrinsic speech library was also implemented, but is easily confounded by environmental noise. Conclusion There is a need for the development of virtual anatomy models to complement traditional education. Initial development is time intensive. Nonetheless, our novel gesture-controlled interactive 3D model of the temporal bone represents a promising interactive teaching tool utilizing a novel interface.

Abstract
A technology enhanced learning and teaching (TELT) solution, radiological anatomy (RA) eLearning, composed of a range of identification-based and guided learning activities related to normal and pathological X-ray images, was devised for the Year 1 nervous and locomotor course at the Faculty of Medicine, University of Southampton. Its effectiveness was evaluated using a questionnaire, pre- and post-tests, focus groups, summative assessment, and tracking data. Since introduced in 2009, a total of 781 students have used RA eLearning, and among them 167 Year 1 students in 2011, of whom 116 participated in the evaluation study. Students enjoyed learning (77%) with RA eLearning, found it was easy to use (81%) and actively engaged them in their learning (75%), all of which were associated to the usability, learning design of the TELT solution and its integration in the curriculum; 80% of students reported RA eLearning helped their revision of anatomy and 69% stated that it facilitated their application of anatomy in a clinical context, both of which were associated with the benefits offered by the learning and activities design. At the end of course summative assessment, student knowledge of RA eLearning relevant topics (mean 80%; SD ±16) was significantly better as compared to topics not relevant to RA eLearning (mean 63%; SD ±15) (mean difference 18%; 95% CI 15% to 20%; P < 0.001). A well designed and integrated TELT solution can be an efficient method for facilitating the application, integration, and contextualization of anatomy and radiology to create a blended learning environment.

Abstract
In a study conducted in 2011, the use of full body digital X-ray images (Lodox(®) Statscan(®)) and drawings were described for surface anatomy education during which suggestions were made by students on how to improve the method. Educational innovations should continuously be adjusted and improved to provide the best possible scenario for student learning. This study, therefore, reports on the efficacy of implementing some of these suggestions. Suggestions incorporated into the follow-up study included: (1) The inclusion of eight strategically placed labeled digital X-ray images to the dissection halls, (2) The placement of both labeled and unlabeled digital X-ray images online, (3) The inclusion of informal oral questions on surface anatomy during dissection, (4) The requirement of students to submit individual drawings in addition to group drawings into their portfolios, and (5) Integrating information on how to recognize anatomical structures on X-rays into gross anatomy lectures given prior to dissection. Students were requested to complete an anonymous questionnaire. The results of the drawings, tests and questionnaires were compared to the results from the 2011 cohort. During 2012, an increased usage of the digital X-rays and an increase in practical test marks in three out of the four modules (statistically significant only in the cardiovascular module) were reported. More students from the 2012 cohort believed the images enhanced their experience of learning surface anatomy and that its use should be continued in future. The suggested changes, therefore, had a positive effect on surface anatomy education.

Abstract
Radiological imaging is gaining relevance in the acquisition of competencies in clinical anatomy. The aim of this study was to evaluate the perceptions of medical students on teaching/learning of imaging anatomy as an integrated part of anatomical education. A questionnaire was designed to evaluate the perceptions of second-year students participating in a clinical anatomy course over three consecutive academic years. A principal component analysis was used to evaluate the dimensionality of the questionnaire. The variables were summarized using frequencies, mean, median, 25th percentile, 75th percentile, minimum, and maximum. The results demonstrated that students felt the teaching of imaging anatomy influenced learning in the clinical anatomy course (mean = 4.5, median = 5.0) and subsequent clinical courses (mean = 4.4, median = 4.0). Regarding the imaging techniques used in the demonstration of anatomical structures, computed tomography (median = 5.0) and magnetic resonance imaging (median = 5.0) were highly rated. Students suggested the use of additional support material (37.6%) and favored a more practical approach. In conclusion, the results of this work highlight the value of imaging anatomy in learning human anatomy. Students' comments pointed out a need to focus teaching/learning programs toward a more practical rather than theoretical approach as well as a need to provide a better fit between sectional anatomy and clinical cases using imaging anatomy. In order to provide an optimal learning environment to students, it also seems important to create improved media material as an additional resource tool.

Abstract
RATIONALE AND OBJECTIVES Radiology has been an increasingly important component of preclinical anatomy instruction since the 1960s. The global status of medical imaging pedagogies and radiologists' roles in medical anatomy education is not well established but is important in determining the specialty's contribution to undergraduate medical education. MATERIALS AND METHODS PubMed was searched with various combinations of MeSH terms including "radiology," "undergraduate medical education," and "anatomy." Articles were reviewed for relevance, and referenced articles of possible relevance were hand-traced to ensure a wide capture of articles. RESULTS Although more medical schools around the world are using medical imaging to teach anatomy, some regions, such as the United States, show a decline in the proportion of imaging taught by radiologists. Lectures, small group discussions, and self-instruction remain the mainstay of current pedagogies and have witnessed dramatic changes over the past few decades with respect to the types of imaging used. Newer pedagogies use contextual and hands-on experiences to improve spatial and application principles. Qualitative and quantitative studies report somewhat mixed results of pedagogical efficacies but demonstrate generally high acceptance by students and instructors and often significant exam score improvement. Radiology as a specialty must overcome several challenges for it to become more involved in anatomy education, including teaching incentives and protected academic time. CONCLUSIONS As anatomy instruction and clinical medicine grow increasingly digital, it is ever more important that radiologists continue to develop new anatomy pedagogies and contribute to anatomy education in greater roles.

Abstract
Anatomists often use images in assessments and examinations. This study aims to investigate the influence of different types of images on item difficulty and item discrimination in written assessments. A total of 210 of 460 students volunteered for an extra assessment in a gross anatomy course. This assessment contained 39 test items grouped in seven themes. The answer format alternated per theme and was either a labeled image or an answer list, resulting in two versions containing both images and answer lists. Subjects were randomly assigned to one version. Answer formats were compared through item scores. Both examinations had similar overall difficulty and reliability. Two cross-sectional images resulted in greater item difficulty and item discrimination, compared to an answer list. A schematic image of fetal circulation led to decreased item difficulty and item discrimination. Three images showed variable effects. These results show that effects on assessment scores are dependent on the type of image used. Results from the two cross-sectional images suggest an extra ability is being tested. Data from a scheme of fetal circulation suggest a cueing effect. Variable effects from other images indicate that a context-dependent interaction takes place with the content of questions. The conclusion is that item difficulty and item discrimination can be affected when images are used instead of answer lists; thus, the use of images as a response format has potential implications for the validity of test items.

Abstract
It has been noted by staff at the Faculty of Health Sciences, Stellenbosch University that medical students neglect the study of surface anatomy during dissection. This study reports on the novel use of Lodox(®) Statscan(®) images in anatomical education, particularly the teaching of surface anatomy. Full body digital X-ray images (Lodox Statscan) of each cadaver (n = 40) were provided to second year medical students. During dissection students were asked to visualize landmarks, organs, and structures on the digital X-ray and their cadaver, as well as palpate these landmarks and structures on themselves, their colleagues, and the cadaver. To stimulate student engagement with surface anatomy, dissection groups were required to draw both the normal and actual position of organs on a laminated image provided. The accuracy of the drawings was subsequently assessed and students were further assessed by means of practical identification tests. In addition, students were asked to complete an anonymous questionnaire. A response rate of 79% was obtained for the student questionnaire. From the questionnaire it was gathered that students found the digital X-ray images beneficial for viewing most systems' organs, except for the pelvic organs. Although it appears that students still struggle with the study of surface anatomy, most students believed that the digital X-rays were beneficial to their studies and supported their continued use in the future.

Abstract
BACKGROUND Radiologic imaging is increasingly utilized as supplemental material in preclinical gross anatomy courses, but few studies have investigated its utility as a fully integrated instructional tool. AIMS Establish the benefit of a teaching method that simultaneously correlates cadaveric and radiologic structures for learning human anatomy. METHOD We performed a mixed-methods randomized controlled trial and one-way cross-over study comparing exam grades and subjective student perception in a gross anatomy course. The intervention consisted of daily direct correlation small group sessions in which students simultaneously identified and correlated radiologic and cadaveric structures. The control method utilized identical laboratory and teaching conditions but students did not simultaneously correlate structures. Spatial relationships of structures within each respective media (gross or radiologic) were emphasized in both groups. RESULTS No significant differences in radiology, gross, or written exam scores were observed between the intervention and control groups. The cross-over group preferred the intervention and control methods equally. The correlation teaching sessions ranked equally with active dissection as the most important instructional components of the course. CONCLUSION Direct, simultaneous correlation of radiologic and cadaveric structures did not affect exam scores or student preference but helped students understand anatomical concepts in comparison with other course components.

Bohl M, Francois W, Gest T. Self-guided clinical cases for medical students based on postmortem CT scans of cadavers. Clin Anat 2011; 24:655-63. [PMID: 21387416 DOI: 10.1002/ca.21143] [Citation(s) in RCA: 36] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2010] [Revised: 01/10/2011] [Accepted: 01/12/2011] [Indexed: 11/12/2022]
Abstract
In the summer of 2009, we began full body computed tomography (CT) scanning of the pre-embalmed cadavers in the University of Michigan Medical School (UMMS) dissection lab. We theorized that implementing web-based, self-guided clinical cases based on postmortem CT (PMCT) scans would result in increased student appreciation for the clinical relevance of anatomy, increased knowledge of cross-sectional anatomy, and increased ability to identify common pathologies on CT scans. The PMCT scan of each cadaver was produced as a DICOM dataset, and then converted into a Quicktime movie file using Osirix software. Clinical cases were researched and written by the authors, and consist of at least one Quicktime movie of a PMCT scan surrounded by a novel navigation interface. To assess the value of these clinical cases we surveyed medical students at UMMS who are currently using the clinical cases in their coursework. Students felt the clinical cases increased the clinical relevance of anatomy (mean response 7.77/10), increased their confidence finding anatomical structures on CT (7.00/10), and increased their confidence recognizing common pathologies on CT (6.17/10). Students also felt these clinical cases helped them synthesize material from numerous courses into an overall picture of a given disease process (7.01/10). These results support the conclusion that our clinical cases help to show students why the anatomy they are learning is foundational to their other coursework. We would recommend the use of similar clinical cases to any medical school utilizing cadaver dissection as a primary teaching method in anatomy education.

Abstract
Publications on anatomy in medical education appear to be largely anecdotal. To explore this, we investigated the literature on anatomy in medical education, aiming first to evaluate the contribution of the literature on anatomy in medical education to "best evidence medical education" (BEME) and second to evaluate the development of this literature toward more "best evidence" between 1985 and 2009. Four databases were searched for publications on anatomy in medical education published between 1985 and 2009, resulting in 525 references. Hundred publications were characterized by five variables (journal category, paper subject, paper category, author perspective, and paper perspective). Statements from these publications were characterized by two variables (category and foundation). The publications contained 797 statements that involved the words "anatomy," "anatomical," or "anatomist." Forty-five percent of the publications contained no explicit research question. Forty percent of the statements made were about "teaching methods" and 17% about "teaching content," 8% referred to "practical value," and 10% to "side effects" of anatomy education. Ten percent of the statements were "positional," five percent "traditional," four percent "self-evident," and two percent referred to "quality of care." Fifty-six percent of the statements had no foundation, 17% were founded on empirical data, and 27% by references. These results substantiated the critical comments about the anecdotal nature of the literature. However, it is encouraging to see that between 1985 and 2009 the number of publications is rising that these publications increasingly focus on teaching methods and that an academic writing style is developing. This suggests a growing body of empirical literature about anatomy education.

Abstract
Radiology and radiologists are recognized as increasingly valuable resources for the teaching and learning of anatomy. State-of-the-art radiology department workstations with industry-standard software applications can provide exquisite demonstrations of anatomy, pathology, and more recently, physiology. Similar advances in personal computers and increasingly available software can allow anatomy departments and their students to build their own three-dimensional virtual models. Appropriate selection of a data-set, followed by processing and presentation are the key steps in creating virtual models. The construction, presentation, clinical application, and educational potential of postprocessed imaging techniques including multiplanar reformats, minimum intensity projections, segmentation, volume-rendering, surface-rendering, fly-throughs, virtual endoscopy, angiography, and cine-loops are reviewed using examples created with only a personal computer and freeware software. Although only static images are presented in this article, further material is available online within the electronic version of this article. Through the use of basic and advanced image reconstruction and also paying attention to optimized presentation and integration, anatomy courses can be strengthened with appropriate radiological material. There are several key advantages for the anatomy department, which is equipped with the ability to produce virtual models using radiology images: (1) Opportunities to present anatomy using state-of-the-art technology as an adjunct to current practices, (2) a means to forge an improved relationship with the local radiology department, and (3) the ability to create material locally, which is integrated with the local curriculum avoiding the problem of information overload when using the internet or other commercially available resources.

Abstract
RATIONALE AND OBJECTIVES The purpose of this study was to assess the implementation of a digital anatomy lecture series based largely on annotated, radiographic images and the utility of the Radiological Society of North America-developed Medical Imaging Resource Center (MIRC) for providing an online educational resource. MATERIALS AND METHODS A series of digital teaching images were collected and organized to correspond to lecture and dissection topics. MIRC was used to provide the images in a Web-based educational format for incorporation into anatomy lectures and as a review resource. A survey assessed the impressions of the medical students regarding this educational format. RESULTS MIRC teaching files were successfully used in our teaching approach. The lectures were interactive with questions to and from the medical student audience regarding the labeled images used in the presentation. Eighty-five of 120 students completed the survey. The majority of students (87%) indicated that the MIRC teaching files were "somewhat useful" to "very useful" when incorporated into the lecture. The students who used the MIRC files were most likely to access the material from home (82%) on an occasional basis (76%). With regard to areas for improvement, 63% of the students reported that they would have benefited from more teaching files, and only 9% of the students indicated that the online files were not user friendly. CONCLUSIONS The combination of electronic radiology resources available in lecture format and on the Internet can provide multiple opportunities for medical students to learn and revisit first-year anatomy. MIRC provides a user-friendly format for presenting radiology education files for medical students.
