Noninvasive Physiologic Assessment of Coronary Stenoses Using Cardiac CT

Figure 1

Curved multiplanar reformation of CCTA (A) shows severe stenosis in the left anterior descending artery (LAD). Coronary angiography (B) demonstrates the occlusion in the proximal LAD. DE-CTP images show hypoperfusion at the anterior, apical, septal, and inferior walls in the two and four-chamber views (C and D). SPECT-MPI images reveal perfusion defects in the same regions (E and F).
