Newer MRI and CT-angiography proved nearly equal in identifying significant stenosis, and were equally accurate in predicting the need for revascularization in patients with known coronary artery disease (CAD), in the first direct comparison of MRA and CTA, say German researchers.
32-channel MRI offers equal accuracy in diagnosing stenosis with CTA, and is less invasive than conventional angiography.
In their study, the researchers led by Dr. Ashraf Hamdan, of the German Heart Institute, compared the diagnostic accuracy of 32-channel, 3.0-T MRI and 64-slice CT scan before conventional x-ray angiography. Their report appeared in the January, 2011, issue of the Journal of the American College of Cardiology: Cardiovascular Imaging.
