The aim of the study was to investigate the prevalence of the noncardiac collateral findings during multislice computed tomography coronary angiography (MSCT-CA).
Six hundred and seventy patients undergoing MSCT-CA with 16-slice and 64-slice CT scanners for suspected atherosclerotic disease of the coronary arteries were retrospectively reviewed. All data sets obtained with a large field of view (FOV) were analysed by two radiologists using standard mediastinal and lung window settings. Collateral findings were divided according to clinical importance into nonsignificant, remarkable and compulsory to be investigated.
Eighty-five percent of patients revealed coronary artery disease (CAD). Only 138/670 (20.6%) were without any additional finding. An additional 1,234 findings were recorded: nonsignificant 332 (26.9%), mild 821 (66.53%), compulsory for study 81 (6.56%). A total of 81 patients (12.08%) had significant noncardiac pathology requiring clinical or radiological follow-up. Among these, newly discovered pathologies were revealed in two patients (2.46%).
A significant number of noncardiac findings might have been missed in MSCT-CA scans; the appropriate approach should be as a team trained in cardiology and radiology.
本研究旨在调查多层螺旋计算机断层扫描冠状动脉造影（MSCT-CA）期间非心脏附带发现的患病率。
回顾性分析670例因疑似冠状动脉粥样硬化疾病而接受16层和64层CT扫描仪进行MSCT-CA检查的患者。两位放射科医生使用标准纵隔和肺窗设置对所有采用大视野（FOV）获得的数据集进行分析。根据临床重要性，将附带发现分为无意义、显著和必须调查三类。
85%的患者显示患有冠状动脉疾病（CAD）。只有138/670（20.6%）的患者没有任何其他发现。共记录了1234项其他发现：无意义的332项（26.9%），轻度的821项（66.53%），必须研究的81项（6.56%）。共有81例患者（12.08%）有需要临床或放射学随访的显著非心脏病变。其中，有两名患者（2.46%）发现了新的病变。
MSCT-CA扫描可能遗漏了大量非心脏发现；合适的方法应该是由经过心脏病学和放射学培训的团队进行检查。
