FFR-CT is formidable in reducing unnecessary invasive angiography
Sunday, November 27 | 11:15 a.m.-11:25 a.m. | SSA04-04 | Room S504ABBelgian radiologists tested noninvasive fractional flow reserve CT (FFR-CT) to find out if it really reduced unnecessary invasive angiographies in chest pain patients undergoing coronary CT angiography. Their answer was yes, emphatically.
