Figure 1 Cardiac SPECT/CTCA: CTCA of the LAD, CRX, and Ramus Intermedius Artery

(A) Computed tomography (CT) angiography curved multiplanar reformation of the left anterior descending coronary artery (LAD) demonstrates an irregular, mostly calcified plaque in the proximal LAD causing significant (>50%) diameter stenosis (solid white arrow). In addition, a hypodense filling defect causing tight luminal stenosis is demonstrated in the mid LAD (dotted arrow) and most probably represents an intraluminal thrombus. (B) The CT angiography curved multiplanar reformations of the left circumflex coronary artery (CRX) and (C) of the ramus intermedius show significant (>50%) diameter stenosis in the proximal part of both arteries (arrows). Figures 1 to 4 present the case of a 72-year-old woman with angina pectoris after recent anterior myocardial infarction. CTCA = computed tomography coronary angiography; LMCA = left main coronary artery; SPECT = single-photon emission computed tomography.
