CORE320: CTA-CTP matches SPECT for gauging cardiac disease
By Eric Barnes
The accuracy of 320-detector-row coronary CT angiography (CTA) combined with CT perfusion (CTP) is equivalent to that of SPECT myocardial perfusion for diagnosing functionally significant coronary artery disease, according to results of the prospective, multicenter, international CORE320 trial published in the European Heart Journal.
