A team of researchers led by Massachusetts General Hospital (MGH) radiologists has developed a computed-tomography-based protocol that identifies both narrowing of coronary arteries and areas from where blood flow to heart muscle tissue is restricted, giving a better indication of clinically significant coronary artery disease. Their report appears in the September 15 issue of the Journal of the American College of Cardiology. Ricardo C Cury, MD, a cardiac imaging specialist at the MGH Heart Center and the study’s principal investigator said “This is among the first demonstrations of the use of cardiac CT [computed tomography] to detect both coronary artery stenosis and resulting myocardial ischemia simultaneously in a single examination.”
