As advanced imaging modalities are developed and interpretation of quantitative imaging techniques becomes more complex, more is needed for improved training and skills assessment. Hence, we have developed a cloud-based platform for training and testing using a case-based and quantitative method, STAT Imaging (Software for Training and Testing).

Online case-based educational platform can be useful in radiology education but design of such systems require focus on the user experience. A continuous user-feedback driven design process can lead to thoughtful engineering and development of effective online tools for radiology education.

Survey results will drive future improvements and serve as an important reminder to focus on user experience. To date, this platform has been instrumental and specifically utilized in the following multi-center clinical trials: Rule Out Myocardial Infarction/Ischemia Using Computer Assisted Tomography trial (ROMICAT II) and PROspective Multicenter Imaging Study for Evaluation of Chest Pain trial (PROMISE). Survey that elicited user feedback illustrated 96% of readers felt that the capabilities of STAT and participation in the CTA case review was interesting and helpful in improving their clinical ability interpretation skills on CTA. Furthermore, we found that 78% of readers felt that the experience reduced variability in their interpretations for cardiac CTA. 75.4% agreed that the CTA cases presented in the module were representative of a wide range of disease severity. Users were also able to learn by viewing cardiac catheterization cine images over the web and 75.4% also felt that this feature was helpful in improving clinical competency.

We sought utilize a user-centric approach to further improve of this online learning platform. A survey was distributed to all the participants of our online Cardiac CTA case-based training module hosted on STAT. Over 65 participants responded to the survey providing answers to structured questions as well as providing free text opinions/feedback to user experience. Respondents were either cardiologists or radiologists and experience ranged from 3 to 35 years in clinical practice.
