Abstract:
Two patients with aortoiliac occlusive disease underwent dynamic and late-static positron emission tomography/computed tomography (PET/CT) acquisitions with 257 and 244 MBq F-18 FDG (CT scan parameters 50 mAs, 120 kV, pitch 1.25). Three-dimensional reconstructions revealed an occluded aortic stent and a high-grade aortic stenosis and demonstrated the relations of vascular pathologies to adjacent structures. Early-dynamic PET can be performed without additional radioactive tracer and may be valuable for evaluation and intervention planning in patients with contraindications to other angiographic modalities.
