用于检测和量化冠状动脉钙化的背景筛查电子束计算机断层扫描（EBCT）检查正在全国范围内进行。除了有关心脏、大血管和冠状动脉的信息外，这些检查还包括部分肺部、骨性胸部和上腹部。本研究的目的是确定在接受 EBCT 扫描冠状动脉钙化筛查研究的一系列患者中，显着的非心脏发现的患病率。 方法和结果 - 2001 年 1 月 1 日至 2001 年 10 月 1 日期间，连续 1326 名患者接受了 EBCT 冠状动脉钙化筛查（每隔 3 分钟获得 3 毫米厚的切片）。两名经过委员会认证的放射科医生使用标准纵隔窗在工作站上审查了检查结果。肺窗、骨窗。注意到明显的心外异常。在 1326 名患者中，103 名（7.8%）有明显的心外病理，需要临床或影像学随访。其中包括 53 名患有非钙化肺结节的患者
Background-Screening electron-beam computed tomography (EBCT) examinations for the detection and quantification of coronary artery calcification are being performed throughout the country. In addition to information about the heart, great vessels, and coronary arteries, these examinations include portions of the lungs, bony thorax, and upper abdomen. The purpose of this study was to determine the prevalence of significant noncardiac findings in it series of patients undergoing coronary artery calcification screening studies with EBCT scanning.Methods and Results-Between January 1, 2001. and October 1, 2001, 1326 consecutive patients underwent coronary artery calcification screening with EBCT (3-mm-thick slices were obtained at 3-min intervals). Two board-certified radiologists reviewed the examinations on a workstation using standard mediastinal windows. lung windows, and bone windows. Significant extracardiac abnormalities were noted. Of 1326 patients, 103 (7.8%) had significant extracardiac pathology requiring clinical or imaging follow-up. These included 53 patients with noncalcified lung nodules
