Abstract
The growing complexity of radiologic examinations and interventional procedures requires frequent exchange of knowledge. Consequently a simple way to share and discuss patient images between radiology experts and with colleagues from other medical disciplines is needed. Aims of this work were the development and initial performance evaluation of a fast and user friendly, platform independent teleconsultation system for medical imaging. A local back end system receives DICOM images and generates anonymized JPEG files that are uploaded to an internet webserver. The front end running on that webserver comprises an image viewer with a specially developed pointer element for indicating findings to collaborative partners. The front end that uses only standard web technologies works on a variety of different platforms, mobile devices and desktop computers. Images can be accessed by simply calling up a special internet address in a web browser that may be exchanged between users (e.g. via email). A speed evaluation of the system showed good results: For example the preparation and upload of a standard head CT took less than 21 seconds. The data volume of the same series and the viewer application could be transferred to a mobile phone in less than 42 seconds via a UMTS network or in less than 3 seconds via a HSPA network. The presented system with its minimal hard- and software requirements, its simplicity and platform independence might be a promising tool in the increasingly important area of teleconsultation.

On-Call Communication in Orthopaedic Trauma: "A Picture Is Worth a Thousand Words"--A Survey of OTA Members. J Orthop Trauma 2015; 29:e194-7. [PMID: 25210834 DOI: 10.1097/bot.0000000000000236] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 02/02/2023]
Abstract
OBJECTIVES To quantify the effects of varying clinical communication styles (verbal and pictorial) on the ability of orthopaedic trauma surgeons in understanding an injury and formulate an initial management plan. METHODS A Research Electronic Data Capture survey was e-mailed to all OTA members. Respondents quantified (5-point Likert scale) how confident they felt understanding an injury and establishing an initial management plan based on the information provided for 5 common orthopaedic trauma scenarios. Three verbal descriptions were created for each scenario and categorized as limited, moderate, or detailed. The questions were repeated with the addition of a radiographic image and then repeated a third time including a clinical photograph. Statistical evaluation consisted of descriptive statistics and Kruskal-Wallis analyses using STATA (version 12.0). RESULTS Of the 221 respondents, there were a total of 95 who completed the entire survey. Nearly all were currently taking call (92/95 = 96.8%) and the majority were fellowship trained (79/95 = 83.2%). Most practice at a level I trauma center (58/95 = 61.1%) and work with orthopaedic residents (62/95 = 65.3%). There was a significant increase in confidence scores between a limited, moderate, and detailed description in all clinical scenarios for understanding the injury and establishing an initial management plan (P < 0.05). There was a significant difference in confidence scores between all 3 types of evidence presented (verbal, verbal + x-ray, verbal + x-ray + photograph) in both understanding and managing the injury for limited and moderate descriptions (P < 0.001). No differences were seen when adding pictorial information to the detailed verbal description. When comparing confidence scores between a detailed description without images and a limited description that includes radiographs and a photograph, no difference in confidence levels was seen in 7 of the 10 scenarios (P > 0.05). CONCLUSIONS The addition of images in the form of radiographs and/or clinical photographs greatly improves the confidence of orthopaedic trauma surgeons in understanding injuries and establishing initial management plans with limited verbal information (P < 0.001). The inclusion of x-rays and photographs raises the confidence for understanding and management with limited verbal information to the level of a detailed verbal description in most scenarios. Mobile technology allows for easy secure transfer of images that can make up for the lack of available information from limited verbal descriptions because of the knowledge base of communicating providers.

Abstract
OBJECTIVE The increasing capabilities of camera-equipped mobile phones have led to a growing body of evidence regarding their use in medical imaging across a broad range of medical specialties. This article reviews the current evidence for the use of mobile health (m-health) in medical imaging. MATERIALS AND METHODS We performed a structured review of the published literature regarding m-health in medical imaging using the Medline, PubMed, and Web of Science databases (January 2002-August 2013). The two authors independently extracted data regarding type of specialty, purpose, and study design of publications. RESULTS In total, 235 articles were identified. The majority of studies were case reports or noncomparative product validation studies. The greatest volume of publications originated in the fields of radiology (21%), dermatology (15%), laboratory techniques (15%), and plastic surgery (12%). Among these studies, m-health was used as diagnostic aids, for patient monitoring, and to improve communication between health practitioners. With the growing use of mobile phones for medical imaging, considerations need to be given to informed consent, privacy, image storage and transfer, and guidelines for healthcare workers and patients. CONCLUSIONS There are several novel uses of mobile devices for medical imaging that show promise across a variety of areas and subspecialties of healthcare. Currently, studies are mostly exploratory in nature. To validate these devices, studies with higher methodological rigor are required.

Abstract
We examined the potential of the iPad 2 as a teleradiologic tool for evaluating brain computed tomography (CT) with subtle hemorrhage in the conventional lighting conditions which are common situations in the remote CT reading. The comparison of the clinician's performance was undertaken through detecting hemorrhage by the iPad 2 and the clinical liquid crystal display (LCD) monitor. We selected 100 brain CT exams performed for head trauma or headache. Fifty had subtle radiological signs of intracranial hemorrhage (ICH), while the other 50 showed no significant abnormality. Five emergency medicine physicians reviewed these brain CT scans using the iPad 2 and the LCD monitor, scoring the probability of ICH on each exam on a five-point scale. Result showed high sensitivities and specificities in both devices. We generated receiver operating characteristic curves and calculated the average area under the curve of the iPad 2 and the LCD (0.935 and 0.900). Using the iPad 2 and reliable internet connectivity, clinicians can provide remote evaluation of brain CT with subtle hemorrhage under suboptimal viewing condition. Considering the distinct advantages of the iPad 2, the popular out-of-hospital use of mobile CT teleradiology would be anticipated soon.

Abstract
BACKGROUND Current mobile phone technology may allow orthopaedic surgeons to make clinical decisions using radiographs viewed on a small mobile device screen. The purpose of this study was to examine the reliability and validity of interpreting ankle fracture images viewed on a mobile device and a computer monitor, with a hypothesis that the agreement in clinical decision making between the mobile device and computer monitor would be high. METHODS A randomized interobserver and intraobserver reliability study was conducted in which 16 mortise and lateral ankle images representing a severity spectrum of malleolar ankle, plafond, and extra-articular tibial fractures were shown to volunteer orthopaedic surgeons on both an Apple fourth-generation iPod Touch and a 23-inch liquid crystal display (LCD) computer monitor. Participants answered a multiple-choice questionnaire for each image regarding diagnosis, severity, need for higher level imaging, need for acute inpatient versus outpatient management, and plan of treatment. Inter- and intraobserver reliability was assessed by kappa (κ), multirater kappa statistics, and intraclass correlation coefficient (ICC). RESULTS Ninety-three orthopaedic surgeon volunteers completed the study. Excellent intraobserver agreement (κ ≥ 0.8) was found for all variables measured, including diagnosis (median κ = 0.84), need for computed tomography scan (κ = 0.86), need for reduction (κ = 0.82), treatment setting (κ = 0.82), and treatment type (κ = 0.87). Interobserver agreement was consistent between the mobile device and computer screen. Interobserver agreement for the severity assessment had a slightly higher ICC for the mobile device compared with the computer monitor (ICC = 0.83 vs 0.79). Sixty-seven percent (62/93) said at the completion of the study they were "completely" or "very" comfortable using a mobile device as a primary viewing device for new emergency room, inpatient, or transfer request consults. CONCLUSIONS Strong reliability for radiographic assessment of ankle injuries existed between a 23-inch computer monitor and a handheld mobile device. Further study is warranted to validate the technology to apply to other anatomic locations and imaging modalities. LEVEL OF EVIDENCE Level II, diagnostic study.

Abstract
PURPOSE The purpose of our study was to demonstrate the feasibility of sending uncompressed digital mammograms in a teleradiologic setting without loss of information by comparing image quality, lesion detection, and BI-RADS assessment. MATERIALS AND METHODS CDMAM phantoms were sent bidirectionally to two hospitals via the network. For the clinical aspect of the study, 200 patients were selected based on the BI-RAD system: 50% BI-RADS I and II; and 50% BI-RADS IV and V. Two hundred digital mammograms (800 views) were sent to two different institutions via a teleradiology network. Three readers evaluated those 200 mammography studies at institution 1 where the images originated, and in the two other institutions (institutions 2 and 3) where the images were sent. The readers assessed image quality, lesion detection, and BI-RADS classification. RESULTS Automatic readout showed that CDMAM image quality was identical before and after transmission. The image quality of the 200 studies (total 600 mammograms) was rated as very good or good in 90-97% before and after transmission. Depending on the institution and the reader, only 2.5-9.5% of all studies were rated as poor. The congruence of the readers with respect to the final BI-RADS assessment ranged from 90% and 91% at institution 1 vs. institution 2, and from 86% to 92% at institution 1 vs. institution 3. The agreement was even higher for conformity of content (BI-RADS I or II and BI-RADS IV or V). Reader agreement in the three different institutions with regard to the detection of masses and calcifications, as well as BI-RADS classification, was very good (κ: 0.775-0.884). Results for interreader agreement were similar. CONCLUSION Uncompressed digital mammograms can be transmitted to different institutions with different workstations, without loss of information. The transmission process does not significantly influence image quality, lesion detection, or BI-RADS rating.

Abstract
OBJECTIVE To assess the feasibility of iPhone-based teleradiology as a potential solution for the diagnosis of acute cervico-dorsal spine trauma. MATERIALS AND METHODS We have developed a solution that allows visualization of images on the iPhone. Our system allows rapid, remote, secure, visualization of medical images without storing patient data on the iPhone. This retrospective study is comprised of cervico-dorsal computed tomogram (CT) scan examination of 75 consecutive patients having clinically suspected cervico-dorsal spine fracture. Two radiologists reviewed CT scan images on the iPhone. Computed tomogram spine scans were analyzed for vertebral body fracture and posterior elements fractures, any associated subluxation-dislocation and cord lesion. The total time taken from the launch of viewing application on the iPhone until interpretation was recorded. The results were compared with that of a diagnostic workstation monitor. Inter-rater agreement was assessed. RESULTS The sensitivity and accuracy of detecting vertebral body fractures was 80% and 97% by both readers using the iPhone system with a perfect inter-rater agreement (kappa:1). The sensitivity and accuracy of detecting posterior elements fracture was 75% and 98% for Reader 1 and 50% and 97% for Reader 2 using the iPhone. There was good inter-rater agreement (kappa: 0.66) between both readers. No statistically significant difference was noted between time on the workstation and the iPhone system. CONCLUSION iPhone-based teleradiology system is accurate in the diagnosis of acute cervicodorsal spinal trauma. It allows rapid, remote, secure, visualization of medical images without storing patient data on the iPhone.

Abstract
BACKGROUND Application and assessment of the usefulness of image transfer through a mobile telephone in pediatric orthopaedic practice was investigated. METHODS Twenty patients with traumatic lesions requiring urgent consultation were included. Relevant x-rays were photographed and transferred using Multimedia Messaging Service to the orthopaedic surgeon at our department. The discussion on the need to transfer the patient for treatment and the final treatment was retrospectively scrutinized by 10 independent orthopaedic surgeons. The agreement on the diagnosis and the management plan proposed after image transfer were assessed. RESULTS The lesion concerned the lower limb in 6 cases, upper limbs in 13 cases, and the spine in 1 case in patients aged 2 to 16 years. The transmitted images were 160 x 120-pixel jpeg files in 1 case, 240 x 180-pixel jpeg files in 8 cases, 320 x 240-pixel jpeg files in 1 case, and 640 x 480-pixel jpeg files in 10 cases. In all the cases studied, all the investigators agreed that the images were good enough for doing the diagnosis even in cases of minor or nondisplaced fractures. The same decisions of transfer or management were taken in all the cases by all the investigators. Review of the transferred images versus the original full-scale images did not change the final diagnosis and management plan. CONCLUSIONS In this study, even in case of low-resolution images (160 x 120-pixel jpeg), images were of sufficiently high quality for interpretation. This enables rational management decisions to be made using this costless and widely available technology. In patients requiring surgical treatment, a final operative decision is mandatory after transfer, bedside examination, and review of other data in addition to images. Teleconsultation using Multimedia Messaging Service is especially useful to improve remote management of orthopaedic patients in local hospitals or for decisions of transfer when surgical treatment is needed. CLINICAL RELEVANCE Level IV (case series).

Abstract
Telemedicine is the specialty of medicine that uses the evolving telecommunications industry combined with medical information technology to provide remote medical services. The use of smartphone telemedicine is an efficient and effective way for remote specialist consultation and should be considered by the oral and maxillofacial surgeon. Smartphones provide fast and clear access to electronically mailed digital images and allows the oral/maxillofacial surgeon free mobility, not restricted by the constraints of a desktop personal computer. This in turn allows for improved efficiency of the specialty consultation and improved triaging, ultimately providing improved care to the maxillofacial patient.

Abstract
OBJECTIVE To assess the impact of using wireless e-mail for clinical communication in an intensive care unit (ICU). DESIGN The authors implemented push wireless e-mail over a GSM cellular network in a 26-bed ICU during a 6-month study period. Daytime ICU staff (intensivists, nurses, respiratory therapists, pharmacists, clerical staff, and ICU leadership) used handheld devices (BlackBerry, Research in Motion, Waterloo, ON) without dedicated training. The authors recorded e-mail volume and used standard methods to develop a self-administered survey of ICU staff to measure wireless e-mail impact. MEASUREMENTS The survey assessed perceived impact of wireless e-mail on communication, team relationships, staff satisfaction and patient care. Answers were recorded on a 7-point Likert scale; favorable responses were categorized as Likert responses 5, 6, and 7. RESULTS Staff sent 5.2 (1.9) and received 8.9 (2.1) messages (mean [SD]) per day during 5 months of the 6-month study period; usage decreased after study completion. Most (106/125 [85%]) staff completed the questionnaire. The majority reported that wireless e-mail improved speed (92%) and reliability (92%) of communication, improved coordination of ICU team members (88%), reduced staff frustration (75%), and resulted in faster (90%) and safer (75%) patient care; Likert responses were significantly different from neutral (p < 0.001 for all). Staff infrequently (18%) reported negative effects on communication. There were no reports of radiofrequency interference with medical devices. CONCLUSIONS Interdisciplinary ICU staff perceived wireless e-mail to improve communication, team relationships, staff satisfaction, and patient care. Further research should address the impact of wireless e-mail on efficiency and timeliness of staff workflow and clinical outcomes.

Abstract
OBJECTIVE The purpose of our study is to describe in detail the use of teleradiology in 2003 and to report on changes since 1999 in this rapidly evolving field. MATERIALS AND METHODS We analyze non-individually identified data from the American College of Radiology's 2003 Survey of Radiologists, a stratified random sample mail survey that achieved a response rate of 63%, and data from the American College of Radiology's 1999 Survey of Practices. Responses were weighted to represent the distribution of individual radiologists and radiology practices nationwide. We present descriptive statistics and multivariable regression analysis results on the prevalence and uses of teleradiology in 2003 and comparisons with 1999. RESULTS Overall, 67% of all radiology practices in the United States, which included 78% of all U.S. radiologists, reported using teleradiology. A significant increase (p < 0.05) was seen in the prevalence of teleradiology or PACS, from 58% of practices in 1999 to 73% in 2003. Regression results indicate that, other practice characteristics being equal, in 2003, primarily academic practices were less likely to use teleradiology than private radiology practices, and medium-sized practices (5-14 radiologists) were more likely to have teleradiology than larger ones. In practices using teleradiology, home was the most frequent receiving site in both 1999 (81%) and 2003 (75%), the percentages being not significantly different. CONCLUSION Already a fixture of radiology practice in 1999, teleradiology increased in prevalence substantially by 2003. The primary use of teleradiology, transmission of images to home, did not change, suggesting that easing the burden of call remains the main use of teleradiology.

Abstract
This paper describes a picture archiving and communication system (PACS) tool based on Web technology that remotely manages medical images between a PACS archive and remote destinations. Successfully implemented in a clinical environment and also demonstrated for the past 3 years at the conferences of various organizations, including the Radiological Society of North America, this tool provides a very practical and simple way to manage a PACS, including off-site image distribution and disaster recovery. The application is robust and flexible and can be used on a standard PC workstation or a Tablet PC, but more important, it can be used with a personal digital assistant (PDA). With a PDA, the Web application becomes a powerful wireless and mobile image management tool. The application's quick and easy-to-use features allow users to perform Digital Imaging and Communications in Medicine (DICOM) queries and retrievals with a single interface, without having to worry about the underlying configuration of DICOM nodes. In addition, this frees up dedicated PACS workstations to perform their specialized roles within the PACS workflow. This tool has been used at Saint John's Health Center in Santa Monica, California, for 2 years. The average number of queries per month is 2,021, with 816 C-MOVE retrieve requests. Clinical staff members can use PDAs to manage image workflow and PACS examination distribution conveniently for off-site consultations by referring physicians and radiologists and for disaster recovery. This solution also improves radiologists' effectiveness and efficiency in health care delivery both within radiology departments and for off-site clinical coverage.

Abstract
The instant transmission of radiological images may be important for making rapid clinical decisions about emergency patients. We have examined an instant image transfer system based on a personal digital assistant (PDA) phone with a built-in camera. Images displayed on a picture archiving and communication systems (PACS) monitor can be captured by the camera in the PDA phone directly. Images can then be transmitted from an emergency centre to a remote physician via a wireless high-bandwidth network (CDMA 1 x EVDO). We reviewed the radiological lesions in 10 normal and 10 abnormal cases produced by modalities such as computerized tomography (CT), magnetic resonance (MR) and digital angiography. The images were of 24-bit depth and 1,144 x 880, 1,120 x 840, 1,024 x 768, 800 x 600, 640 x 480 and 320 x 240 pixels. Three neurosurgeons found that for satisfactory remote consultation a minimum size of 640 x 480 pixels was required for CT and MR images and 1,024 x 768 pixels for angiography images. Although higher resolution produced higher clinical satisfaction, it also required more transmission time. At the limited bandwidth employed, higher resolutions could not be justified.
