Subjective image quality
BLIND
Two radiologists, one with 5 years and the other with 10 years of experience in CCTA diagnosis, were asked to assess the subjective image quality independently, where the cases were randomized and the observers were kept blind to the scanning protocol. The evaluation was performed for vessels with a diameter > 1.5 mm on MIP reconstruction images according to the 18‐segment classification system.Coronary CT angiography: examples of different levels of image quality. Right coronary artery (RCA) with score of 2−4 (a‐c); Left anterior descending (LAD) coronary artery with score of 2−4 (d‐f).
