MDCT Accurate In Detecting Stenosis In Calcified Coronary Artery Plaque

Multidetector CT angiography can accurately predict the presence of obstructive disease (stenosis) in small and moderate-sized calcified coronary artery plaque (CAP), and is even fairly accurate in diagnosing large and heavily calcified CAP, according to a recent study conducted by researchers at Thomas Jefferson University Hospital in Philadelphia, PA.

The study evaluated 31 patients who had one or more calcified CAP, comparing the results from CCTA to cardiac catheterization. "It is commonly believed that when coronary artery plaque is calcified, (particularly when it is heavily calcified), MDCT is unreliable in determining the degree of stenosis," said David C. Levin, MD, lead author of the study. However, in this study CCTA and cardiac catheterization were concordant in 58 of 61 small calcified CAPs (95%), 20 of 22 moderate-sized (91%) and 29 of 43 large calcified CAPs (67%).
