Results: Implementing the Receiver Operating Characteristic (ROC) test on the data for MDCT-measured leaflet billowing received from MDCT angiography suggests that the area under the ROC curve is 96% for a declared variable, which is absolutely significant ( P < 0.001), and MDCT-measured leaflet billowing is an appropriate index for the diagnosis of mitral valve prolapse.
