Contrast-enhanced MR angiography of abdominal aorta and lower extremity

Contrast-enhanced MR angiography of abdominal aorta and lower extremity

Protocol:

1.5Tesla.

Contrast Enhanced Angio performed with 3D TOF (Time of flight) sequence. The study viewed in row as well as 3D reconstructed images. The procedure performed in single session with I.V. 25cc Gadolinium (Multihance). MIP images of each side were produced separately to prevent superimposition on the lateral projections. Mask images obtained followed bolus chasing, the rapid moving-table technique used.

1st slab covering thoraco abdominal aorta at the level of diaphragm to femorals up to the level of inguinal ligament , 2nd slab covering lower limb major arteries femoral at the level of inguinal ligament to  level of knee joint and 3^rd slab covering free knee downwards. Pasting of all three slabs done.
