The rapid progress in both hardware and software of MR imaging technique are now going to continue. This article contains brief answers to the clinical usefulness of the ultrafast- and fast-imaging techniques involving EPI, FSE or TSE and MP-RAGE, and it also contains phased-array coil system and respiratory-gated imaging technique. The high-spatial-resolution. T2-weighted images provide us fine and exact anatomical information about lesions, tissues and organs and the high-time-resolution T1-weighted imaging studies using extracellular or hepatobiliary contrast agents provide us more exact functional information about those.
