Aortic Dissection - intraluminal view Takayasu arteritis Takayasu arteritis Renal MRA (3T): with 3d T1 T1 double fat sat, IR gad Vascular Protocols Coronary Chest Abdomen Peripheral vascular Bolus Chase: Stepping Table MRA 1 2 9 - 12 sec 9 - 11 sec F. Scott Pereles MD 3 11-13 sec x 2 runs
Hybrid pMRA Approach 3 stations BUT 2 Injections • Calf and foot station - 20 ml Gad and 2 or 3 acquisitions • Pelvis & Thigh stations with step table - 25 – 35 ml Gad bolus chase style • Improved resolution at all stations • Avoids venous contamination in the feet and calves. F. Scott Pereles MD Hybrid pMRA F. Scott Pereles MD Hybrid Approach 3 stations BUT 2 Injections • 2 separate timing runs (pelvis & calves) - Axial timing run, proximal calf 2 ml Gad @ 2 ml/sec (20ml saline flush @ 2ml/sec) - Axial timing run, aortic bifurcation 2 ml Gad @ 2 ml/sec (20ml saline flush @ 2ml/sec) F. Scott Pereles MD Hybrid Technique Timing Run 2 nd Acquisition, better visualization of foot vessels F. Scott Pereles MD Time Resolved MRA (TREAT, TRICKS) F.
