Gadobutrol (GB) and gadoterate meglumine (GM) are contrast agents used for contrast-enhanced magnetic resonance angiography (CEMRA). Supraaortic vasculature (SAV) CEMRAs are used to evaluate stroke risk and neurologic symptoms. There is a need to compare the SAV CEMRA image quality obtained with GB and GM.To intra-individually compare MRA images obtained with equimolar GB and GM at 1.5 T in the SAV.Prospective, crossover.Twenty-eight subjects (54 ± 13 years; 17 female).1.5 T; three-dimensional (3D) gradient recalled echo.Quantitative image quality was measured by normalized signal intensity (SISINo significant difference in SIAt 1.5 T and equimolar demonstration, GB (0.1 mL/kg, i.e., 0.1 mmol/kg) showed higher CRs in the SAV compared to GM (0.2 mL/kg, i.e., 0.1 mmol/kg) at most vessels. Subjective image quality was not significantly different between the two agents for most vessels.2 TECHNICAL EFFICACY: Stage 2. |
