PurposeTo compare a protocol with higher-concentration macrocyclic gadolinium-based contrast agent (GBCA) [study group] to the traditional protocol with lower-concentration linear GBCAs [control group] for breath-held arterial phase MRI.Material and MethodsA total of 136 patients were quantitatively evaluated for image quality (IQ), breathing artifacts (BA), and timing of the arterial phase (Tap).Quantitative analysis was also performed.ResultsNo significant differences in IQ, BA and Tap (P>.05).Study group exhibited less enhancement of the aorta (P=.0091) and smaller standard deviation for the portal vein enhancement (P=.0173).ConclusionSimilar arterial-phase image quality can be achieved with a macrocyclic GBCA compared to traditional linear GBCA.
