Figure 3 Coronary Artery Disease by MDCT Coronary Angiography With Normal Myocardial Perfusion
A 60-year old male presented to the outpatient clinic with dyspnea and an elevated risk profile for coronary artery disease, including hypertension, hypercholesterolemia, and smoking. Contrast-enhanced multidetector computed tomography (MDCT) coronary angiography revealed considerable atherosclerosis in the left anterior descending coronary artery (A). B and C are cross-sectional images of the areas indicated by the arrows in (A). In contrast, myocardial perfusion imaging (D), which was performed during exercise stress (first and third row) and rest (second and fourth row), showed normal perfusion. On intravascular ultrasound imaging (E and F), considerable plaque burden was demonstrated, yet with preserved coronary lumen.
