Calcification of coronary arteries: detection and quantification with double-helix CT.

摘要: PURPOSE: To evaluate the accuracy of double-helix computed tomography (CT) in coronary artery calcification detection and quantification. MATERIALS AND METHODS: One hundred sixty patients with disease (135 men, 25 women; age range, 45-62 years), whom 138 had obstructive (stenosis > 50% diameter; n = 129) or mild ( 83%) than normal arteries (27%) healthy control subjects (34%; P < .01). Sensitivity detecting CAD was high (91%); however, specificity low (52%) because nonobstructive lesions. Comparison CT angiographic findings indicated that 84% accurate positive negativ...
