Noninvasive diagnosis of vulnerable coronary plaque

Figure 2 Coronary plaque categories by coronary computed tomography. Patient with chest pain referred for CCT. A: LAD in multiplanar reconstruction with a mixed plaque in the mid segment (arrow) that causes significant stenosis confirmed in the ICA (B, arrow). Note that there is also a nonsignificant noncalcified plaque in the proximal segment (red arrow) that is barely seen in coronariography (B, red arrow); C: A maximum intensity projection that demonstrates a severely calcified plaque in the ostial RCA (arrowhead), which does not allow luminal stenosis evaluation. However, ICA (D) confirms the absence of significant stenosis at the same level (arrowhead). CCT: Coronary computed tomography; LAD: Left anterior descending coronary artery; ICA: Invasive coronary angiography; RCA: Right coronary artery.
