Fast MR imaging techniques: Impact in the abdomen

The increased efficiency of MRI data acquisition has had a substantial impact on clinical MRI of the abdomen. Five particular applications that have thus been affected include breath‐hold imaging of liver lesions (including detection, characterization, and biopsy), MR cholangiopan‐ creatography, practical chemical shift imaging (including liver and adrenal glands), dynamic imaging after contrast media injection, and MR angiography.
