Study Finds CT Scans Are Effective Tool In Detecting Coronary Artery Disease

Computed tomography (CT) angiography is as accurate as an invasive angiogram in detecting coronary artery disease, according to the findings of the first two prospective multicenter 64-slice scanner trials presented at the annual meeting of the Radiological Society of North America (RSNA).

The Coronary Artery Evaluation Using 64-Row Multidetector Computed Tomography Angiography (CORE-64) Trial - conducted by researchers at nine international centers, including Beth Israel Deaconess Medical Center - studied 291 patients who were scheduled to undergo invasive coronary angiography for suspected or unknown coronary artery disease. The study found that 64-slice multidetector CT angiography was highly accurate in detecting blockages of greater than 50 percent, with a sensitivity of 85 percent and a specificity of 90 percent. The noninvasive exam was equal in accuracy to invasive angiography in its ability to identify patients to be referred for angioplasty or bypass surgery.
