Methods: 120 students who came to our department for internship from August 2019 to August 2020 were selected as research objects and randomly divided into observation group and control group. The control group adopted traditional multimedia teaching and the observation group adopted PACS system practice teaching. The assessment results and teaching satisfaction of the two groups of students were analyzed and compared. Results: after the two groups received different teaching interventions, the examination results and teaching satisfaction of students in the observation group were significantly higher than that in the control group, and the difference was significant and statistically significant (P < 0.05). Conclusion: in the practice teaching of medical imaging, the use of PACS system teaching has a better teaching effect. It is worth learning and popularizing.展开更多

The workflow times have been directly read from RIS database. In particular, Execution and Reporting steps were considered. Afterwards, data have been analyzed through a statistical elaboration and results were compared with data, coming from studies performed on similar process, collected with a stopwatch method. Possible “bottlenecks” can be evidenced in the process structure. Moreover, comparing hospitals with the same RIS/PACS system, different internal organization is emphasized.展开更多

The purpose of this study is to determine if specific CT and MR sequences can be interpreted accurately on mobile device/PACS software platforms when compared to a traditional stationary high resolution monitor/PACS radiological workstation. If so, this allows radiologists to provide comparable interpretation as if they were onsite at an imaging center or hospital. Materials and Methods: This study is an investigator initiated, single site, retrospective, nonrandomized, IRB approved study. Five radiologists were included in this study. Each independently interpreted specific CT and MR sequences on traditional high-resolution LCD monitors via eFilm? software as well as an iPad? mobile device using Osirix? software program. Repeat interpretations were performed, with 4 weeks minimum interval between interpretations of each patient. This investigation included: 50 patients with CTA perfusion imaging, 50 patients with MRI of the brain, and 50 patients with MRI of the spine, which were image study orders generated through emergency room requests. Subsequently, interpretive results of each radiologist for each patient were statistically compared to evaluate for intra-observer and inter-observer reliability. Results: The parameters set within the CTA perfusion brain studies demonstrated excellent intra-observer variability. All of the parameters within the MRI brain studies demonstrated excellent intra-observer variability with a Cohen’s kappa value > 0.75. The Cohen’s kappa values for the board certified neuroradiologist demonstrated excellent variability for all parameters;the resident radiologists had good variability, with a majority of kappa values near 0.75. Conclusions: The data and statistical analysis demonstrated that portable mobile devices such as the Apple iPad? can display adequate resolution of CT and MRI sequences to accurately diagnose acute central nervous system injuries and other non-acute pathology.展开更多
