CORE320: CTA-CTP matches SPECT for gauging cardiac disease

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.

Breaking bad news: Some docs are more willing than others

It's no surprise that residents and radiologists don't like breaking bad news to patients with serious medical conditions. But a survey from Pakistan suggests some types of medical specialists are more willing to tell patients the awful truth, while others pass the job along to the referring physician.
