  REVIEW ARTICLE

Gadolinium based contrast agents (GBCAs) are T1-shortening agents that result in marked elevation of signal on T1-weighted (T1W) images. GBCA enhancement is crucial in the detection and characterization of abdominal diseases. It provides at least two additional imaging properties that facilitate diagnosis: the pattern of blood delivery (i.e., capillary enhancement) and the size and/or rapidity of drainage of the interstitial space (i.e., interstitial enhancement) [1,2]. This review describes important aspects for the achievement of high-quality diagnostic GBCA enhanced images and discusses critical issues related to their optimized use... [ ...continue ]
