AbstractCoronary artery calcification (CAC) is a known risk factor for adverse outcomes in the general population and in patients with coronary artery disease. We performed a survey of United States radiologists to evaluate the trends in reporting the presence or absence of CAC on NCCT examinations. An 11 multiple-choice questionnaire was distributed to members of the American College of Radiology, and 530 members participated in the study. Eighty-seven percent of the analyzed group report the presence of CAC on standard CT scans of the chest, and approximately half them (52 %) use a qualitative modifier. Only 32 % of cardiac imagers were aware of the published data correlating qualitative and quantitative calcium scores on non-gated chest CT examinations compared to 17 % of non-cardiac imagers. We believe that subjective or objective grading of coronary calcified plaque burden on standard chest CT exams is warranted as it may not only help risk-stratify patients, but also may eliminate the need for dedicated CACS in many patients and may be useful in treatment guidance.
