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 the right coronary artery (RCA), left anterior descending artery (LAD), and diagonal branches (D1, D2). (B) Curved multiplanar reformation image using CoronaViz software shows the 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
3.0-T contrast-enhanced whole-heart CMRA images of a 54-year-old female patient. Maximum intensity projection image (A) of CMRA detects a significant stenosis in the middle RCA (arrow), with good correlation with X-ray angiography (arrow) (B). Both readers interpreted this as significant stenosis on the basis of CMRA images. Abbreviations as in Figure 2.

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 CMRA maximum intensity projection images show a significant stenosis in the proximal LCX and a nonsignificant stenosis in the middle 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; OM = obtuse marginal artery; other abbreviations as in Figure 2.
