Objective To explore the clinical value of dual-source CT coronary angiography (CTCA) in diagnosis artery disease (CAD) flying personnel. Methods Ten personnel, who were suspected CAD, underwent both CTCA and conventional (CCA). The CCA results served as Fgolden standard to evaluate diagnostic seusibility, specificity accuracy diagnosing stenosis. Results All 10 personnel accepted successfully. Satisfied image quality was obtained 96.3% all images. Fifteen segments diagnosed stenosis 7 images, while myocardial bridge 2 fistula 1. According results, sensitivity, segment (≥50%) 100.0%, 98.2%, 98.4% 80.0%, 99.2%, 98.4%, respectively. Conclusion As a noninvasive method which could accurately, is valuable diagnose CAD safely reliably.
