Objective: To increase the probability of successful renal artery angiography with a three-dimensional contrast-enhanced magnetic resonance angiography (3D CE-MRA).
Methods: 3D CE-MRA was performed in 33 patients with hypertension. To calculate the scan delay time, a testing contrast agent bolus of 2 ml was injected for single sagittal slice real-time scanning, followed by oblique coronal 3D Fast TOF SPGRE.
