 Association of Contrast Medium Arrival Time with Conventional Risk Factors and Morise Score in Detecting Obstructive Coronary Artery Disease

Objectives: To determine the association of contrast medium arrival time during coronary CT angiography with the conventional coronary risk factors and Morise score in detecting obstructive CAD. Materials and Methods: A total of 665 patients were retrospectively included in the study. Contrast medium arrival time was recorded as the time from the start of the injection to the threshold of 100 HU at the descending aorta during the bolus tracking scan. The Morise score was calculated for each patient and modified Morise score (MMS) was define... view more»
