Coronary 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.
冠状动脉钙化（CAC）是一般人群和冠状动脉疾病患者不良结局的已知危险因素。我们对美国放射科医生进行了一项调查，以评估在非增强CT（NCCT）检查中报告有无CAC的趋势。向美国放射学会成员发放了一份包含11道选择题的问卷，530名成员参与了该研究。在分析的组中，87%的人在胸部标准CT扫描中报告存在CAC，其中约一半（52%）使用了定性修饰词。与17%的非心脏影像医生相比，只有32%的心脏影像医生知晓已发表的关于非门控胸部CT检查中定性和定量钙评分相关性的数据。我们认为，对标准胸部CT检查中的冠状动脉钙化斑块负荷进行主观或客观分级是有必要的，因为这不仅可能有助于对患者进行风险分层，还可能消除许多患者进行专门的冠状动脉钙化扫描（CACS）的必要性，并且可能对治疗指导有用。
