Gadolinium-enhanced three-dimensional MR angiography of the entire aorta and iliac arteries with dynamic manual table translation.
Spoiled fast three-dimensional gradient-echo magnetic resonance imaging of the aorta and iliac arteries was performed in 13 patients after administration of a single bolus of gadopentetate dimeglumine. The imaging table was moved manually 40-45 cm between two acquisitions. Arterial signal-to-noise ratio did not vary significantly between the thoracic (aortic) and pelvic stations, but venous signal-to-noise ratios increased and arterial contrast-to-noise ratios decreased on the pelvic studies. This method was feasible and increased anatomic coverage.
