3T versus 1.5T MR angiography in peripheral arterial occlusive disease: an equivalence trial in comparison with digital subtraction angiography

The arterial tree in each patient was divided into 27 segments, infrarenal aorta, common and external iliac arteries, common and superficial femoral arteries, popliteal arteries in thigh and calf station, tibiofibular trunk, proximal and distal halves of the anterior and posterior tibial arteries an...

Description
Summary:The arterial tree in each patient was divided into 27 segments, infrarenal aorta, common and external iliac arteries, common and superficial femoral arteries, popliteal arteries in thigh and calf station, tibiofibular trunk, proximal and distal halves of the anterior and posterior tibial arteries and peroneal arteries. There is an excellent correlation between MR angiography and digital subtraction angiography (C). [figure omitted; refer to PDF] Table 1 Diagnostic performance for stenosis detection at 3T versus 1.5T contrast-enhanced MRA Conclusions Standardized single-injection 3-station moving-table 3T CE-MRA is reliable for stenosis detection and classification in POAD with equivalent diagnostic performance as 1.5T CE-MRA, while CNR significantly increased at 3T for identical contrast dosage.
