Unenhanced Respiratory-Gated Magnetic Resonance Angiography (MRA) of Renal Artery in Hypertensive Patients Using True Fast Imaging With Steady-State Precession Technique Compared With Contrast-Enhanced MRA

OBJECTIVE: This study was aimed to evaluate the accuracy of “True Fast Imaging with Steady-State Precession” (TrueFISP) MR angiography (MRA) for diagnosis of renal arterial stenosis (RAS) in hypertensive patients. METHODS: Twenty-two patients underwent both TrueFISP MRA and contrast-enhanced MRA (CE... Full description

description: OBJECTIVE: This study was aimed to evaluate the accuracy of “True Fast Imaging with Steady-State Precession” (TrueFISP) MR angiography (MRA) for diagnosis of renal arterial stenosis (RAS) in hypertensive patients. METHODS: Twenty-two patients underwent both TrueFISP MRA and contrast-enhanced MRA (CE-MRA) on a 1.5-T MR imager. Volume of main renal arteries, length of maximal visible renal arteries, number of visualized branches, stenotic grade, and subjective quality were compared. Paired 2-tailed Student t test and Wilcoxon signed rank test were applied to evaluate the significance of these variables. RESULTS: Volume of main renal arteries, length of maximal visible renal arteries, and number of branches indicated no significant difference between the 2 techniques (P > 0.05). Stenotic degree of 10 RAS was greater on CE-MRA than on TrueFISP MRA. Qualitative scores from TrueFISP MRA were higher than those from CE-MRA (P < 0.05). CONCLUSIONS: TrueFISP MRA is a reliable and accurate method for evaluating RAS.
