An ultra-fast, 320-detector computed tomography (CT) scanner can accurately sort out which people with chest pain need -- or don’t need -- an invasive procedure such as cardiac angioplasty or bypass surgery to restore blood flow to the heart, according to an international study. Results of the study, which involved 381 patients at 16 hospitals in eight countries, are scheduled to be presented at the European Society of Cardiology Congress in Munich, Germany, on August 28.
