Lee S, Kim EK, Chung SY, Shin HJ. Efficient Collaboration Between Radiologists Using the PACS-Integrated Refer Function to Reduce Communication Times. J Digit Imaging 2023; 36:1995-2002. [PMID: 37407844 PMCID: PMC10501968 DOI: 10.1007/s10278-023-00876-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2023] [Revised: 06/21/2023] [Accepted: 06/23/2023] [Indexed: 07/07/2023] Open
Abstract
The purpose of this study was to assess the utility of a picture archiving and communication systems (PACS)-integrated refer function for improving collaboration between radiologists and radiographers during daily reading sessions. Retrospective analysis was conducted on refers sent by radiologists using a PACS-integrated refer system from March 2020 to December 2021. Refers were categorized according to receiver: radiologists in the same division (intra-division), radiologists in a different division (inter-division), and radiographers. The proportions of answered refers, content of refers, and timing of refer posts were evaluated. Additionally, time intervals in minutes from initial refer post to refer response were assessed to assess the efficiency of the refer system and compared according to receivers using the Mann-Whitney U test. Among a total of 691 refers posted by radiologists, 579 (83.8%) were answered directly using the refer function in PACS. Of the answered refers, 346 refers (59.8%) were made between radiologists, and 173 (50%) were intra-division refers. About the content of refers, about 82.6% of radiologists' refers were about imaging interpretation consultation, and about 98.9% of refers from radiologists to radiographers were for image quality control. The median time interval until refer response was 9 min, and this response time did not differ between intra-division and inter-division refers (p = 0.998). Of the refers that got responses, 74.3% (257/346) were sent among radiologists before official reports were made, and the median time until refer response was 9-10 min. The proportion of refers answered by radiographers was 85.7% (233/272). The median time interval until refer response by radiographers was 87 min for all refers, and 63% were made within 6 h. Therefore, the PACS-integrated refer function can facilitate communication between radiologists for image interpretation and quality control.

JCO Clin Cancer Inform 2022; 6:e2200066. [PMID: 36084275 PMCID: PMC9848557 DOI: 10.1200/cci.22.00066] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2022] [Revised: 07/27/2022] [Accepted: 08/09/2022] [Indexed: 01/26/2023] Open
Abstract
PURPOSE To evaluate whether a custom programmatic workflow manager reduces reporting turnaround times (TATs) from a body oncologic imaging workflow at a tertiary cancer center. METHODS A custom software program was developed and implemented in the programming language R. Other aspects of the workflow were left unchanged. TATs were measured over a 12-month period (June-May). The same prior 12-month period served as a historical control. Median TATs of magnetic resonance imaging (MRI) and computed tomography (CT) examinations were compared with a Wilcoxon test. A chi-square test was used to compare the numbers of examinations reported within 24 hours and after 72 hours as well as the proportions of examinations assigned according to individual radiologist preferences. RESULTS For all MRI and CT examinations (124,507 in 2019/2020 and 138,601 in 2020/2021), the median TAT decreased from 4 (interquartile range: 1-22 hours) to 3 hours (1-17 hours). Reports completed within 24 hours increased from 78% (124,127) to 89% (138,601). For MRI, TAT decreased from 22 (5-49 hours) to 8 hours (2-21 hours), and reports completed within 24 hours increased from 55% (14,211) to 80% (23,744). For CT, TAT decreased from 3 (1-19 hours) to 2 hours (1-13 hours), and reports completed within 24 hours increased from 84% (82,342) to 92% (99,922). Delayed reports (with a TAT > 72 hours) decreased from 17.0% (4,176) to 2.2% (649) for MRI and from 2.5% (2,500) to 0.7% (745) for CT. All differences were statistically significant (P < .001). CONCLUSION The custom workflow management software program significantly decreased MRI and CT report TATs.

Abstract
Many facets of an image acquisition workflow leave a digital footprint, making workflow analysis amenable to an informatics-based solution. This paper describes a detailed framework for analyzing workflow and uses acute stroke response timeliness in CT as a practical demonstration. We review methods for accessing the digital footprints resulting from common technologist/device interactions. This overview lays a foundation for obtaining data for workflow analysis. We demonstrate the method by analyzing CT imaging efficiency in the setting of acute stroke. We successfully used digital footprints of CT technologists to analyze their workflow. We presented an overview of other digital footprints including but not limited to contrast administration, patient positioning, billing, reformat creation, and scheduling. A framework for analyzing image acquisition workflow was presented. This framework is transferable to any modality, as the key steps of image acquisition, image reconstruction, image post processing, and image transfer to PACS are common to any imaging modality in diagnostic radiology.

Abstract
RATIONALE AND OBJECTIVES Efficiency is central to current radiology practice. Knowledge of report generation timing is essential for workload optimization and departmental staffing decisions. Yet little research evaluates the distribution of activities performed by neuroradiologists in daily work. MATERIALS AND METHODS This observational study tracked radiologists interpreting 358 brain magnetic resonance imaging (MRI) in an academic practice over 9 months. We measured the total duration from study opening to report signing and times for five activities performed during this period: image viewing, report transcription, obtaining clinical data, education, and other. Attendings, fellows, and residents reading studies independently and attendings over-reading trainee-previewed studies were observed. RESULTS Ten attendings, 12 fellows, and 13 residents spent a mean of 11, 18, and 16 minutes reading brain MRIs independently. Mean duration was significantly different comparing attendings in all assignments to fellows (18.36 ± 1.05 minutes, p = 0.0001) or residents (16.31 ± 1.11 minutes, p = 0.001) but not between fellows/residents. Mean duration among attendings reading independently versus over-reading trainees was not statistically different. Attendings spent the same time on image viewing (4.07-5.33 minutes) with or without trainees. Attending transcription time was shortest when over-reading trainees (2.24 minutes) and longest when reading independently (4.20 minutes), demonstrating benefit of the draft report. Fellows and Residents spent longer on image viewing (7.14 minutes and 8.06 minutes, respectively) and transcription (7.02 minutes and 5.40 minutes, respectively) than attendings reading independently. CONCLUSION Neuroradiologist time/activity distributions for reading brain MRI studies were measured, setting the stage to establish a benchmark for future reference and suggesting opportunities for greater efficiency. Furthermore, report production time can be decreased when a draft report is available.

Abstract
Increasingly, radiologists' workplaces revolve around PACS and digital imaging. Use of these technologies can lead to repetitive strain injuries, many of which can be exacerbated by specific features of a radiology practice environment. Ergonomic approaches, such as proper reading room structure, lighting, temperature, noise, and equipment setup, can help decrease the frequency and severity of repetitive strain injuries and improve radiologist productivity. However, ergonomic approaches are complex, include all aspects of the radiology practice environment, and are best implemented along with proper training of the practicing radiologists. The ergonomic approaches considered most important by members of the ACR Commission on Human Resources are presented in this report, and this information may serve as an aid in departmental planning.

Abstract
In this paper, statistical analysis and techniques from process mining are employed to analyze interaction patterns originating from radiologists reading medical images in a picture archiving and communication system (PACS). Event logs from 1 week of data, corresponding to 567 cases of single-view chest radiographs read by 14 radiologists, were analyzed. Statistical analysis showed that the numbers of commands and command types used by the radiologists per case only have a slightly positive correlation with the time to read a case (0.31 and 0.55, respectively). Further, one way ANOVA showed that the factors time of day, radiologist and specialty were significant for the number of commands per case, whereas radiologist was also significant for the number of command types, but with no significance of any of the factors on time to read. Applying process mining to the event logs of all users showed that a seemingly "simple" examination (single-view chest radiographs) can be associated with a highly complex interaction process. However, repeating the process discovery on each individual radiologist revealed that the initially discovered complex interaction process consists of one group of radiologists with individually well-structured interaction processes and a second smaller group of users with progressively more complex usage patterns. Future research will focus on metrics to describe derived interaction processes in order to investigate if one set of interaction patterns can be considered as more efficient than another set when reading radiological images in a PACS.

Abstract
Although the implementation of picture archiving and communication system (PACS) could increase productivity of radiology departments, this depends on factors such as the PACS competence of radiologic technologists (RTs). The purpose of this study was to investigate the RTs' perceptions of PACS competence and educational issues in Western Australia (WA). A hardcopy questionnaire was distributed to WA RTs for obtaining their perceptions of PACS competence and educational issues. Descriptive (percentage of frequency, mean and standard deviation) and inferential statistics (t test and analysis of variance) were used to analyze the responses of the multiple choice and five-point scale questions from the returned questionnaires. The questionnaire response rate was 57.7% (173 out of 300). The mean values of all PACS competence questions except questions 2e-g are in the range of 3.9-4.9, i.e., around competent to very competent. Participants indicated they received adequate PACS training (mean 3.8). Statistically significant variables influencing RTs' perceptions of their PACS competence and educational issues including the age (p < 0.01), gender (p < 0.05), years of practice (p < 0.005-0.05), primary duty (p < 0.05), medical imaging qualification (p < 0.001), general computer skills (p < 0.001), and type of PACS education received (p < 0.001-0.05). The WA RTs indicated that they were competent in using the modality workstation, PACS and radiology information system, and received adequate training. However, future PACS education programs should be tailored to different RTs' groups. For example, multiple training modules might be necessary to support the PACS competence development of older RTs and those with lower general computer literacy.

Abstract
We reviewed the literature for the impact of service delivery initiatives (SDIs) on patients' waiting times within radiology departments. We searched MEDLINE, EMBASE, CINAHL, INSPEC and The Cochrane Library for relevant articles published between 1995 and February, 2013. The Cochrane EPOC risk of bias tool was used to assess the risk of bias on studies that met specified design criteria. Fifty-seven studies met the inclusion criteria. The types of SDI implemented included extended scope practice (ESP, three studies), quality management (12 studies), productivity-enhancing technologies (PETs, 29 studies), multiple interventions (11 studies), outsourcing and pay-for-performance (one study each). The uncontrolled pre- and post-intervention and the post-intervention designs were used in 54 (95%) of the studies. The reporting quality was poor: many of the studies did not test and/or report the statistical significance of their results. The studies were highly heterogeneous, therefore meta-analysis was inappropriate. The following type of SDIs showed promising results: extended scope practice; quality management methodologies including Six Sigma, Lean methodology, and continuous quality improvement; productivity-enhancing technologies including speech recognition reporting, teleradiology and computerised physician order entry systems. We have suggested improved study design and the mapping of the definitions of patient waiting times in radiology to generic timelines as a starting point for moving towards a situation where it becomes less restrictive to compare and/or pool the results of future studies in a meta-analysis.

Abstract
OBJECTIVES The main objective of this study is to learn more on the image use and search requirements of radiologists. These requirements will then be taken into account to develop a new search system for images and associated meta data search in the Khresmoi project. METHODS Observations of the radiology workflow, case discussions and a literature review were performed to construct a survey form that was given online and in paper form to radiologists. Eye tracking was performed on a radiology viewing station to analyze typical tasks and to complement the survey. RESULTS In total 34 radiologists answered the survey online or on paper. Image search was mentioned as a frequent and common task, particularly for finding cases of interest for differential diagnosis. Sources of information besides the Internet are books and discussions with colleagues. Search for images is unsuccessful in around 25% of the cases, stopping the search after around 10 minutes. The most common reason for failure is that target images are considered rare. Important additions for search requested in the survey are filtering by pathology and modality, as well as search for visually similar images and cases. Few radiologists are familiar with visual retrieval but they desire the option to upload images for searching similar ones. CONCLUSIONS Image search is common in radiology but few radiologists are fully aware of visual information retrieval. Taking into account the many unsuccessful searches and time spent for this, a good image search could improve the situation and help in clinical practice.

Abstract
This article explores the perspectives of two user groups, general practitioners (GPs) and consultant radiologists (CRs), on the rollout of picture archiving and communications systems (PACS) within acute trusts and eventually to primary care as part of the electronic patient record. Qualitative interviews were conducted with 16 CRs and 31 GPs. Analysis was carried out using a grounded theory approach. Radiologists expressed positive views about the implementation of PACS in secondary care, but were wary of GPs accessing radiological images. GPs expressed concerns about the added burdens that PACS might bring to primary care, but most felt that sharing images with patients could benefit doctor—patient communication and increase patient satisfaction. This study highlights both impediments and pathways to the implementation of PACS in primary care, and illustrates the importance of regarding PACS as socially embedded and users as culturally disparate.

Abstract
PURPOSE To determine the effect of sedative and anesthetic administration on the duration and costs of pediatric magnetic resonance (MR) imaging. MATERIALS AND METHODS This prospective study was approved by the institutional research ethics board; informed consent and/or assent was obtained from all participants or their parents. A patient flow study was conducted in a pediatric MR imaging clinic in which research assistants tracked participants' progress through the clinic. Demographic, visit process, and medication information was collected for 237 participants, categorized as awake, sedated, or anesthetized. The data were analyzed to (a) determine total visit duration differences, (b) investigate variations in visit stage durations according to patient type, and (c) estimate visit costs on the basis of human resource and medication use. Linear regression, the Shapiro-Wilk test, the two-tailed t test, and the nonparametric Mann-Whitney test were used. RESULTS Complete data sets were obtained for 148 awake, 28 sedated, and 27 anesthetized participants. Data revealed 12 stage sequences among patient visits; dominant sequences differed according to patient category. An awake patient's average visit duration (2 hours 21 minutes) differed significantly from that of sedated (3 hours 38 minutes, P < .001) and anesthetized (4 hours 7 minutes, P < .001) patients; sedated and anesthetized visit durations did not differ significantly (P < .073), although this finding may be attributable to the small sample sizes. Variation in stage durations was also evident within and among patient types. Visit costs for sedated and anesthetized patients were 3.24 and 9.56 times higher, respectively, than those for awake patients. Costs for anesthetized patients were 2.95 times higher than those for sedated patients. CONCLUSION Visit durations were significantly longer for anesthetized and sedated patients. Anesthetized patients incurred the highest costs, followed by sedated patients.

Abstract
Over the past decade, there have been many developments that have changed the practice of radiology and the education of radiology residents. These include workforce issues, the institution of the Accreditation Council for Graduate Medical Education duty-hours restrictions, the increased use of night float systems, and the implementation of picture archiving and communication systems as well as voice recognition. This article reviews the impact on resident education, summarizes potential problems introduced by these changes, and examines proposed solutions.

Abstract
RATIONALE AND OBJECTIVES The aim of the study is to measure the impact of a picture archive and communication system (PACS) on dictation turnaround time of chest radiographs in a multisite hospital and relate variations across sites to local factors and implementation strategy. MATERIALS AND METHODS The multisite hospital is composed of three sites. Dictation turnaround time was calculated by using data obtained from the radiology information system for examinations performed during three 90-day periods (immediately before PACS implementation, immediately after PACS implementation, and 1 year after implementation). Productivity, expressed as number of examinations dictated per full-time-equivalent radiologist, also was calculated. For each 3-month period, average interval delay was calculated. Values for average interval delay obtained during the different pre- and post-PACS periods were compared by using analysis of variance. This was done for each hospital. RESULTS In the immediate post-PACS period at site 1, dictation turnaround time decreased 5% (P < .05), whereas productivity decreased 16.5%. The implementation strategy was revised for the next two sites, and dictation turnaround time decreased 21% (P < .001) in both sites in the immediate post-PACS period. Productivity increased 2% and 3% in these sites. One year after implementation, decreases in turnaround ranged from 28% to 55% (P < .001) in the three sites. CONCLUSION Our experience suggests that PACSs cannot be isolated from their contexts; therefore, implementation strategy matters in the realization of projected benefits. In addition, regardless of differences in film-based environments before PACS, all three sites benefited from conversion to filmless operation, with the greatest benefits seen in the site that was least efficient before implementation.

Abstract
RATIONALE AND OBJECTIVES To measure the change in radiologists' productivity in terms of interpretation time per examination when using picture archiving and communication system (PACS) workstations in a particular private practice, Valley Radiologists, Ltd, as part of a feasibility study and subsequent business plan to implement a digital enterprise. MATERIALS AND METHODS Time to process a series of exams was measured for 18 radiologists during an uninterrupted period of a working day. Radiologists in the practice served in multiple locations. The data were analyzed in aggregate and by modality (plain film, ultrasound, computed tomography, and magnetic resonance imaging). Average time per exam, with and without PACS, was measured for each modality. Regression analysis was used to determine the independent effect of PACS on radiologist productivity. RESULTS The mean time to process an exam was 1.4 minutes (SE = 0.04) for plain film, 1.96 minutes (SE = 0.14) for ultrasound, 5.08 minutes (SE = 0.44) for computed tomography, and 6.83 minutes (SE = 0.31) for magnetic resonance imaging. Regression results indicate that PACS had no effect on the time taken to read a series of exams. CONCLUSIONS When considering a PACS purchase or implementation, decrease in radiologists' time to process an examination may not be realized. In this specific practice setting, we did not find evidence that PACS workstations alone, without any other changes in workflow design, improved radiologists' interpretation time.

Abstract
PURPOSE The purpose of this study was to determine factors that would affect radiologists' productivity in private group practices in California. METHODS Individual productivity data were collected for 236 private practice radiologists from 6 private radiology groups in California. The data included information on physician characteristics, facility indicators, and group practice factors that were hypothesized to affect providers' productivity. Statistical tests including chi-square testing and multivariate linear regression were used to analyze the effect of the 3 groupings of factors on the productivity of the radiologists. RESULTS With increases in age, the number of years in practice, and the number of years in affiliation with the group practice, productivity seemed to decrease. On the other hand, productivity tended to increase if a radiologist was a shareholder, with an increase in the number of facilities served by the radiologist per day, in the proportion of imaging examinations and interventional procedures conducted, and in the proportion of those examinations stored in picture archiving and communication systems. CONCLUSIONS To improve radiologists' productivity, group practices must invest in data-reporting infrastructure for tracking productivity, contract with outpatient imaging centers, and review group practice partnership composition and incentive models to ensure higher productivity. Future studies might consider examining the effect of other factors, such as time spent on nonclinical duties and the use of paramedical assistants in the practice.

Abstract
There has been an increase in the use of digital imaging in recent years and radiologists have almost universally accepted the use of computers in their day-to-day work. Completely filmless radiology departments, with all reporting being done on visual display terminals and picture archiving and communications systems (PACS) around the department, are already a reality in many places in the UK and other parts of the world. There is a constant need of computers for literature searches on the web, e-mails, communication and preparing lectures and presentations. With this explosive increase in the use of computers in the hospital, it is imperative that the use of computer monitor screens for medical use is optimized in order to avoid eyestrain and fatigue. This is especially important as tired eyes and brains may be more likely to commit errors. We have reviewed the current literature to elaborate a few useful measures that can be taken to minimize the effect of excessive computer use in a soft-copy radiology reporting area on the eyes and the musculoskeletal system. We recommend that optimal placement of computer monitors with user-friendly PACS terminal interfaces will ensure greater acceptability and improve reporting efficiency and accuracy. Good work practices to ensure reduction of reporting errors are highlighted.

Abstract
Technological progress and the rising cost pressure on the healthcare system have led to a drastic change in the work environment of radiologists today. The pervasive demand for workflow optimization and increased efficiency of its activities raises the question of whether by employment of electronic systems, such as RIS and PACS, the potentials of digital technology are sufficiently used to fulfil this demand. This report describes the tasks and structures in radiology departments, which so far are only insufficiently supported by commercially available electronic systems but are nevertheless substantial. We developed and employed a web-based, integrated workplace system, which simplifies many daily tasks of departmental organization and administration apart from well-established tasks of documentation. Furthermore, we analyzed the effects exerted on departmental workflow by employment of this system for 3 years.

Abstract
RATIONALE AND OBJECTIVES An attempt to finance a large-scale multi-hospital picture archival and communication system (PACS) solely based on cost savings from current film operations is reported. MATERIALS AND METHODS A modified Request for Proposal described the technical requirements, PACS architecture, and performance targets. The Request for Proposal was complemented by a set of desired financial goals-the main one being the ability to use film savings to pay for the implementation and operation of the PACS. RESULTS Financing of the enterprise-wide PACS was completed through an operating lease agreement including all PACS equipment, implementation, service, and support for an 8-year term, much like a complete outsourcing. Equipment refreshes, both hardware and software, are included. Our agreement also linked the management of the digital imaging operation (PACS) and the traditional film printing, shifting the operational risks of continued printing and costs related to implementation delays to the PACS vendor. An additional optimization step provided the elimination of the negative film budget variances in the beginning of the project when PACS costs tend to be higher than film and film-related expenses. CONCLUSION An enterprise-wide PACS has been adopted to achieve clinical workflow improvements and cost savings. PACS financing was solely based on film savings, which included the entire digital solution (PACS) and any residual film printing. These goals were achieved with simultaneous elimination of any over-budget scenarios providing a non-negative cash flow in each year of an 8-year term.

Abstract
RATIONALE AND OBJECTIVES The purpose of this study was to assess the impact on times of verification (TOVs) by a pager notification system (PNS) that informs physicians when reports are available for signature. MATERIALS AND METHODS An automated PNS was implemented in the authors' department in November 2000. Monthly report verification times of each physician were collected for 3 months in the years before and after initiation of the PNS. Radiologists enrolled in the PNS and those who were not were assigned into two groups for analysis. Mean TOVs for the two sets of 3 months and for the two groups were calculated and differences recorded. Two-tailed t tests were used to assess for statistical differences between the groups. RESULTS Twenty-nine of 37 radiologists voluntarily enrolled in the PNS (group 1). Mean TOV was 26.75 hours (standard deviation [SD] = 17.76) for these physicians before and 14.48 hours (SD = 11.86) after the PNS was employed (P < .01). For those physicians who did not enroll in the PNS, mean TOV was 11.53 hours (SD = 5.55) before and 9.77 hours (SD = 9.86) after the PNS was employed (P = .33). Both the absolute and percentage reductions in TOVs were significantly greater for those physicians enrolled in the PNS than for those who were not (P = .035). Twenty-three of 29 (79%) physicians who used the PNS showed a reduction in their report turnaround times. CONCLUSION Linking the PNS with the radiology information system to notify physicians of unsigned reports was effective in reducing report verification times.

Abstract
OBJECTIVE The purpose of our study was to model the supply and demand for diagnostic radiologists over the next 30 years under alternative scenarios. MATERIALS AND METHODS We used responses from the American College of Radiology's 2000 Survey of Diagnostic Radiologists and Radiation Oncologists to determine the current age distribution and activity of diagnostic radiologists. The numbers entering the profession were projected using three assumptions: no change in training programs, reduction of residency to 3 years (or otherwise increasing the annual number of graduates by one third), and elimination of most fellowship programs. Demand projections assume a 5% shortage in 2001 and depend on growth rates of the population, aging, scenarios of growth of age-standardized demand, and the effect of possibly productivity-enhancing technologies such as PACS (picture archiving and communication systems). RESULTS Only a one-third increase in annual graduates materially increases the work-force relative to current training patterns. In all cases, the growth rate of the demand for radiologists far outstrips the supply over a 30-year horizon. In the shorter term, projections of current trends point to an increasing shortage, but rapid major productivity increases could produce a surplus. CONCLUSION Those in the field of diagnostic radiology should consider measures to mitigate the increasing shortage, while monitoring developments that might signal departures from current trends in supply and demand.

Abstract
RATIONALE AND OBJECTIVES The authors performed this study to investigate the impact of changing from a film-based image interpretation system to one using digital image workstations on the training of radiology residents in the interpretation of radiographs. MATERIALS AND METHODS Data were collected during a period when a conventional system of image interpretation with hard-copy images and multiviewers was used and during a period when digital image workstations were used. During each period, it was noted whether the first interpretation of the radiographs was performed by a radiology resident, by an attending radiologist, or as a group effort including both an attending radiologist and a radiology resident(s). In addition, it was noted whether a radiology resident or an attending radiologist dictated the report. RESULTS The proportion of images first interpreted by the radiology resident alone decreased from 38% (53 of 139) when using the conventional system to 17% (34 of 199) after the switch to interpreting images on the workstations (P = .001). During the film-based period, radiology residents dictated 45% of reports (141 of 312), but during the workstation period, radiology residents dictated only 4% of reports (24 of 667; P = .001). CONCLUSION The authors observed a decrease in autonomous participation by radiology residents in image interpretation and dictation of reports and an increase in "group reading" after the switch from a film-based system to a workstation system.

Abstract
Voice recognition (VR) and picture archiving and communication system (PACS) both have advantages and disadvantages in radiologic practice. We describe a fully integrated VR/PACS system running on a single platform. Integration optimizes the positive features of both systems and creates a synergy that is not otherwise realized. The planning and development of the system is described, as well as a number of challenges that were addressed. Radiologists have viewed the process changes very positively during initial use.
