Both datasets were motion corrected after registration of CTA to PET. For the hybrid acquisition the required adjustments were 0.5, 2.5 and 0mm in the x,y and z axis respectively. For prior CTA dataset PET had to be moved by 2.5, 3 and 5mm in the corresponding axes. Lesions with increased tracer uptake were identified in the left main, lesion TBR 1.56 and 1.55 (A and A’) and proximal right coronary artery, lesion TBR 1.60 and 1.60 (B and B’). CTA= coronary CT angiography. TBR= target to background ratio.
