Figure 2 3.0-T Contrast-Enhanced Whole-Heart CMRA Images of 71-Year-Old Woman With Normal Coronary Arteries
Contrast-enhanced whole-heart cardiac magnetic resonance angiography (CMRA) images of a 71-year-old woman with normal coronary arteries. (A) Volume-rendered image provides an overview of coronary anatomy and clearly depicts right coronary artery (RCA), left anterior descending artery (LAD), and diagonal branches (D1, D2). (B) Curved multiplanar reformation image using CoronaViz software shows left main artery (LM), LAD, left circumflex artery (LCX), and RCA.

Figure 3 3.0-T Contrast-Enhanced Whole-Heart CMRA Images of 54-Year-Old Woman With Coronary Artery Stenosis
Contrast-enhanced whole-heart cardiac magnetic resonance angiography (CMRA) images of a 54-year-old woman. (A) Maximum intensity projection image of CMRA detects a significant stenosis in the middle right coronary artery (RCA) (arrow), with good correlation with (B) X-ray angiography. Both readers interpreted this as significant stenosis on the basis of CMRA images.

Figure 4 3.0-T Contrast-Enhanced Whole-Heart CMRA Images of a 75-Year-Old Man With Atypical Chest Pain
(A, B) Contrast-enhanced whole-heart cardiac magnetic resonance angiography (CMRA) maximum intensity projection images show a significant stenosis in the proximal left circumflex artery (LCX) and a nonsignificant stenosis in the middle right coronary artery (RCA) (arrows), respectively. (C, D) The volume-rendered images (Syngo InSpace, Siemens AG Healthcare, Erlangen, Germany) have the same findings in LCX and RCA (arrows), which were consistent (E, F) with the findings (arrows) of conventional coronary angiography. AO = aorta; LAD = left anterior descending artery; LM = left main coronary artery; OM = obtuse marginal artery.
