Diagnostic value of 3T whole heart coronary magnetic resonance angiography (MRA) without contrast medium

Methods From May 1 to September 6 in 2012, 31 consecutive patients received whole heart coronary MRA without contrast medium in 3T MRI scanner (Ingenia 3.0T, Philips Healthcare). 26 patients (84%) had sufficient quality to analyze. In these, 21 patients (16 men; mean age 69 years) received coronary angiography within 1 month of MRA. In MRA, coronary arteries were segmented to proximal, mid, distal RCA (segment 1, 2, 3), LMT (segment 5), proximal, mid, distal LAD (segment 6, 7, 8), and proximal, distal LCX (segment 11, 13). In coronary angiography, a stenosis of over 50% was defined to be significant. The segments after stent implantation were excluded.
