3D TOF FSPGR
Occlusion of abdominal aorta just after giving off of renal.
Aorta at its bifurcation, common iliac, internal and external ilac on either side show very poor flow related signals.
Reconstitution of normal flow related signals in common femoral and onwards at the level of inguinal ligament appears to be from collaterals.
