[Breath-hold 3D MR urography with 2 ml Gd-DTPA injection].
Breath-hold gadolinium-enhanced 3D MR urography was performed in five healthy volunteers. Enhanced 3D fast gradient-echo with a spectral IR pulse sequence was used for depicting MR urography, which was obtained 5-10 minutes after the injection of 2 ml of gadopentate dimeglumine (0.013-0.02 mmol/kg). The urinary tract was depicted as a high-signal intensity area, and detectability of the non-dilated urinary tracts was superior to that of heavy T2-weighted images. At the same time, comparison between the urinary tract and vascular structure could be made using breath-hold contrast-enhanced 3D MR angiography with an additional Gd-DTPA injection.
