VIPER: Effective training for medical imaging

To address a training shortfall for medical imaging students at Christchurch Polytechnic Institute of Technology in New Zealand, a team has initiated the VIPER project -- an intelligent tutoring system that allows students to test their knowledge against an online tool, giving them detailed feedback as they attempt to solve problems.

Ischemia in the circumflex territory. F-18 flurpiridaz PET showed a perfusion defect in the lateral wall during pharmacological stress, which improved in rest. Myocardial blood flow (MBF) quantification showed decreased MBFstress (1.4 mL/min/g) and myocardial flow reserve (MFR) (2.2) in the circumflex (Cx) territory, with adequate flow in the left anterior descending and right coronary artery territories, MBFstress 2.6 and 2.2 mL/min/g, and MFR 3.4 and 3.1, respectively. Coronary angiography showed a 70%-99% stenosis in the Cx artery, for which percutaneous coronary intervention was performed with good result and good clinical outcome.
