Abstract
PURPOSE Anatomical understanding is an important basis for medical teaching, especially in a surgical context. The interpretation of complex vascular structures via two-dimensional visualization can yet be difficult, particularly for students. The objective of this study was to investigate the feasibility of an MxR-assisted educational approach in vascular surgery undergraduate education, comparing an MxR-based teaching-intervention with CT-based material for learning and understanding the vascular morphology of the thoracic aorta. METHODS In a prospective randomized controlled trial learning success and diagnostic skills following an MxR- vs. a CT-based intervention was investigated in 120 thoracic aortic visualizations. Secondary outcomes were motivation, system-usability as well as workload/satisfaction. Motivational factors and training-experience were also assessed. Twelve students (7 females; mean age: 23 years) were randomized into two groups undergoing educational intervention with MxR or CT. RESULTS Evaluation of learning success showed a mean improvement of 1.17 points (max.score: 10; 95%CI: 0.36-1.97). The MxR-group has improved by a mean of 1.33 [95% CI: 0.16-2.51], against 1.0 points [95% CI: -0.71- 2.71] in the CT-group. Regarding diagnostic skills, both groups performed equally (CT-group: 58.25 ± 7.86 vs. MxR-group:58.5 ± 6.60; max. score 92.0). 11/12 participants were convinced that MxR facilitated learning of vascular morphologies. The usability of the MxR-system was rated positively, and the perceived workload was low. CONCLUSION MxR-systems can be a valuable addition to vascular surgery education. Further evaluation of the technology in larger teaching situations are required. Especially regarding the acquisition of practical skills, the use of MxR-systems offers interesting application possibilities in surgical education.

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.

Online interactive medical neuroimaging exercise to identify human brain structures. Ann Anat 2023; 249:152101. [PMID: 37209871 DOI: 10.1016/j.aanat.2023.152101] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2022] [Revised: 01/19/2023] [Accepted: 04/20/2023] [Indexed: 05/22/2023]
Abstract
A persisting need remains for developing methods for inspiring and teaching undergraduate medical students to quickly learn to identify the hundreds of human brain structures, tracts and spaces that are clinically relevant (viewed as three-dimensional volumes or two-dimensional neuroimages), and to accomplish this with the option of virtual on-line methods. This notably includes teaching the essentials of recommended diagnostic radiology to allow students to be familiar with patient neuroimages routinely acquired using magnetic resonance imaging (MRI) and computed tomography (CT). The present article includes a brief example video plus details a clinically oriented interactive neuroimaging exercise for first year medical students (MS1s) in small groups, conducted with instructors either in-person or as an entirely online virtual event. This "find-the-brain-structure" (FBS) event included teaching students to identify brain structures and other regions of interest in the central nervous system (and potentially in head and neck gross anatomy), which are traditionally taught using brain anatomy atlases and anatomical specimens. The interactive, small group exercise can be conducted in person or virtually on-line in as little as 30minutes depending on the scope of objectives being covered. The learning exercise involves coordinated interaction between MS1s with one or several non-clinical faculty and may include one or several physicians (clinical faculty and/or qualified residents). It further allows for varying degrees of instructor interaction online and is easy to convey to instructors who do not have expertise in neuroimaging. Anonymous pre-event survey (n=113, 100% response rate) versus post-event surveys (n=92, 81% response rate) were attained from a cohort of MS1s in a neurobiology course. Results showed multiple statistically significant group-level shifts in response several of the questions, showing an increase in MS1 confidence with reading MRI images (12% increase shift in mean, p<0.001), confidence in their approaching physicians for medical training (9%, p<0.01), and comfort levels in working online with virtual team-based peers and with team-based faculty (6%, p<0.05). Qualitative student feedback revealed highly positive comments regarding the experience overall, encouraging this virtual medium as a desirable educational approach.

Abstract
OBJECTIVE We aimed to explore to what extent the literature supports that the use of cadaveric computed tomography can play an important role in anatomy education. MATERIALS AND METHODS PubMed, SCOPUS, Education Resources Information Center and Cochrane Databases were searched for papers with purpose to explore the outcomes of the use of cadaveric computed tomography scans in anatomy education. The following data were obtained from each paper: authors, number of participants, type of study (comparative or not), level of outcome according to Kirkpatrick hierarchy, possible evaluation of statistical significance, acquisition of anatomical knowledge after the educational intervention and perceptions about the effectiveness of this intervention in anatomy learning. RESULTS Seven articles were included. Four of them evaluated students' knowledge after the use of cadaveric computed tomography scans in anatomy education and three papers evaluated only students' perceptions. Generally, the outcomes, which mainly concerned students' perceptions, were positive, while it was showed that students' academic performance may also be improved. CONCLUSIONS The outcomes of the use of cadaveric computed tomography scans in anatomy education encourage the implementation of this teaching modality in anatomy curricula. Further research, including comparative studies with evaluation of acquisition of students' knowledge, is needed to show if cadaveric computed tomography will be proved a remarkable supportive tool in anatomy educators' hands.

Abstract
PURPOSE With the increasing significance of diagnostic imaging in clinical practice, long-term anatomical education and training is required to ensure that students can reliably distinguish anatomical structures and interpret images. To improve students' motivation and prospects for learning imaging anatomy, we developed an integrated anatomical practice program combining cadaveric dissection with cadaver CT data processing and analysis during undergraduate students' dissection courses. METHODS Workstations imported with post-mortem CT data of dissected cadavers and various forms of clinical CT/MRI data were set in the dissection room. Medical students had free access to the imaging data during cadaver dissection, and they were challenged to process and analyze the data for submission of voluntary imaging reports on their topics of interest. Finally, we surveyed the integrated anatomical education of 481 medical students. RESULTS The positive response rate to the integrated anatomical practice was 74.9%, and 79.4% of the students answered that this form of practice offered a suitable introduction to anatomical imaging. The usefulness of this approach in understanding the 2- to 3D arrangement of the human body and enhancing interest in anatomy was also confirmed. The submission rate of voluntary imaging reports also increased annually and is currently 97.4%. CONCLUSION Our integrated anatomical practice only allowed students to actively browse CT images and facilitated imaging processing and analysis of their region of interest. This practice may improve students' long-term ability to analyze images and deepen their understanding. A competitive imaging contest may help improve students' motivation when they begin learning imaging anatomy.

Strengths and Weaknesses of Non-enhanced and Contrast-enhanced Cadaver Computed Tomography Scans in the Teaching of Gross Anatomy in an Integrated Curriculum. ANATOMICAL SCIENCES EDUCATION 2022; 15:143-154. [PMID: 33170986 DOI: 10.1002/ase.2034] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/25/2020] [Revised: 10/20/2020] [Accepted: 11/05/2020] [Indexed: 06/11/2023]
Abstract
Cadaver-specific postmortem computed tomography (PMCT) has become an integral part in anatomy teaching at several universities. Recently, the feasibility of contrast-enhanced (CE)-PMCT has been demonstrated. The purpose of this study was to identify particular strengths and weaknesses of both non-enhanced and contrast-enhanced PMCT compared to conventional cadaver dissection. First, the students' perception of the learning effectiveness of the three different modalities have been assessed using a 34-item survey (five-point Likert scale) covering all anatomy course modules. Results were compared using the nonparametric Friedman Test. Second, the most frequent artifacts in cadaver CT scans, were systematically analyzed in 122 PMCT and 31 CE-PMCT data sets to quantify method-related limitations and characteristics. Perfusion quality was assessed in 57 vascular segments (38 arterial and 19 venous). The survey was answered by n = 257/320 (80.3%) students. Increased learning benefits of PMCT/ CE-PMCT compared to cadaver dissection were found in osteology (2/3 categories, P < 0.001), head and neck (2/5 categories, P < 0.01), and brain anatomy (3/3 categories, P < 0.01). Contrast-enhanced-PMCT was perceived particularly useful in learning vascular anatomy (10/10 categories, P < 0.01). Cadaver dissection received significantly higher scores compared to PMCT and CE-PMCT in all categories of the abdomen and thorax (7/7 categories, P < 0.001), as well as the majority of muscular anatomy (5/6 categories, P < 0.001). Frequent postmortem artifacts (total n = 28, native-phase n = 21, contrast injection-related n = 7) were identified and assessed. The results of this work contribute to the understanding of the value of integrating cadaver-specific PMCT in anatomy teaching.

Abstract
Postmortem computed tomography (PMCT) is a standard image modality used in forensic death investigations. Case- and audience-specific visualizations are vital for identifying relevant findings and communicating them appropriately. Different data types and visualization methods exist in 2D and 3D, and all of these types have specific applications. 2D visualizations are more suited for the radiological assessment of PMCT data because they allow the depiction of subtle details. 3D visualizations are better suited for creating visualizations for medical laypersons, such as state attorneys, because they maintain the anatomical context. Visualizations can be refined by using additional techniques, such as annotation or layering. Specialized methods such as 3D printing and virtual and augmented reality often require data conversion. The resulting data can also be used to combine PMCT data with other 3D data such as crime scene laser scans to create crime scene reconstructions. Knowledge of these techniques is essential for the successful handling of PMCT data in a forensic setting. In this review, we present an overview of current visualization techniques for PMCT.

Abstract
The presentation of pre-sliced specimens is a frequently used method in the laboratory teaching of cross-sectional anatomy. In the present study, a new teaching method based on a hands-on slicing activity was introduced into the teaching of brain, heart, and liver cross-sectional anatomy. A randomized, controlled trial was performed. A total of 182 third-year medical students were randomized into a control group taught with the prosection mode (pre-sliced organ viewing) and an experimental group taught with the dissection mode (hands-on organ slicing). These teaching methods were assessed by testing the students' knowledge of cross-sectional specimens and cross-sectional radiological images, and analyzing students' feedback. Using a specimen test on three organs (brain, heart, and liver), significant differences were observed in the mean scores of the control and experimental groups: for brain 59.6% (±14.2) vs. 70.1% (±15.5), (P < 0.001, Cohen's d = 0.17); for heart: 57.6% (±12.5) vs. 75.6% (±15.3), (P < 0.001, d = 0.30); and for liver: 60.4% (±14.5) vs. 81.7% (±14.2), (P < 0.001, d = 0.46). In a cross-sectional radiological image test, better performance was also found in the experimental group (P < 0.001). The mean scores of the control vs. experimental groups were as follows: for brain imaging 63.9% (±15.1) vs. 71.1% (±16.1); for heart imaging 64.7% (±14.5) vs. 75.2% (±15.5); and for liver imaging 61.1% (±15.5) vs. 81.2% (±14.6), respectively. The effect sizes (Cohen's d) were 0.05, 0.23, and 0.52, respectively. Students in the lower tertile benefited the most from the slicing experiences. Students' feedback was generally positive. Hands-on slicing activity can increase the effectiveness of anatomy teaching and increase students' ability to interpret radiological images.

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
BACKGROUND This study assesses the scope for using technology to supplement the undergraduate anatomy curriculum at medical school. METHODS A narrative literature review explored the current landscape of anatomy learning. Medical student usage and preferences of technological interventions for anatomy learning were then explored through a cross-sectional survey. RESULTS The literature review revealed the current teaching strategies for anatomy learning, exploring recent multimedia innovations. The survey demonstrated that technology usage was ubiquitous among medical students with 98% of medical students owning smartphones. Medical education apps were used by 64.3% of medical students, with 61.9% of these apps covering anatomy, and 60.4% of students preferring traditional cadaveric teaching to other technological interventions. CONCLUSION Novel technological innovations present the opportunity to deliver accessible and standardised teaching of anatomy to medical students. Many students already use smartphone applications as part of their anatomy learning. Uptake of smartphones and other devices provides opportunities to reach larger target audiences. However, traditional cadaveric teaching remains the learning resource of choice for medical students, and technological interventions are best designed as adjuncts or supplements to cadaveric teaching.

Abstract
Recently, faculty at Pritzker School of Medicine, The University of Chicago, have made efforts to improve the depth of radiological anatomy knowledge that students have, but no insights exist as to student and resident opinions of how clinically helpful deep anatomical understanding is. A single-institution survey of second- and fourth-year medical students and postgraduate year 1-4 residents from 11 specialties, composed of five-point Likert questions, sample examination questions, and narrative response questions, was distributed in 2015. One hundred seventy-seven of the 466 potential respondents replied (71 residents and 106 students), response rate 38.0%. No nonresponse bias was present in two separate analyses. Respondents generally favored a superficial "identification" question as more relevant to clinical practice, which was positively associated with increasing clinical experience ρ = 0.357, P < 0.001 by point-biserial correlation. Students and residents most commonly used self-directed methods to learn medical imaging during their medical anatomy courses (72.6 and 57.7%, respectively). Small group education was least commonly used by students and residents (45.3 and 39.4%, respectively), but most commonly recommended (62.3 and 69%, respectively). A total of 56.6 and 64.8% of students and residents, respectively, reported that having multiple learning methods was "quite" or "extremely" important. Respondents with more clinical experience were more likely to report that a superficial identification question was more clinically relevant than a question testing deeper radiological anatomy knowledge. Small group learning was preferred among students and residents but was the least commonly employed method of instruction. Both findings contrast starkly with current radiological anatomy instructional understanding and practices. Anat Sci Educ 11: 25-31. © 2017 American Association of Anatomists.
