Prevalence of significant noncardiac findings on electron-beam computed tomography coronary artery calcium screening examinations

Research output: Contribution to journalArticle

Abstract

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 a 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-mm 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
