Figure 1
Figure 1
Upper row: baseline ECG compatible with subacute inferior wall myocardial infarction. Lower row: ST-segment elevation in lead III, AVF with reciprocal depression in leads AVL and V2-4 during stress
Figure 2
Figure 2
CTCA shows total occlusion of midtraject of the RCA, the distal segment shows contrast opacification caused by collateral filling
Figure 3
Figure 3
3D fusion of the parametric perfusion PET, with the RCA derived from the CTCA, during rest (left) and vasodilation (right) with corresponding colorscale of absolute perfusion ranging from 0 to 1.0 expressed in mL/minute/g of perfusable tissue. The PET/CT stress images reveal a small perfusion defect during rest which expands to the inferior, inferoseptal, and inferolateral wall during vasodilation
Figure 4
Figure 4
Parametric polar map of absolute quantitative myocardial perfusion (mL/minute/g of perfusable tissue) at rest (right upper quadrant), stress (left upper quadrant), and flow reserve (left lower quadrant). A decreased flow reserve is displayed in inferior, inferolateral, and inferoseptal wall with according quantitative parameters

Angiographic images showing the coronary lesion of the RCA before (A) and after stenting (B). Arrow indicates coronary lesion
