Figure 2 Typical examples of reformatted magnetic resonance (MR) (left panels), and multidetector row computed tomography (MDCT) (center panels) and corresponding quantitative coronary angiography (QCA) images (right panels) of the right (RCA) (top panels) and left coronary artery systems (LCA) (bottom panels). (A) Normal right and left coronary arteries by MR, MDCT, and QCA. (B) Isolated mid-RCA stenosis (arrows) evaluated at 40% diameter stenosis (DS) using MR, 58% DS using MDCT, and 86% DS by QCA. (C) Two-vessel disease involving the mid-LAD (black arrows), evaluated at 37% DS using MR, 51% DS using MDCT, and 52% DS using QCA and left circumflex coronary artery (white arrows) evaluated at 64% DS using MR, 57% DS using MDCT, and 79% DS using QCA.
