MRI can provide clinically-valuable images for hepatic diseases and has become the most accurate noninvasive method in evaluating liver lesions. With the development of high and ultrahigh field MRI, liver images may be acquired within breath-hold period using very short TE, essentially reducing scanning time and motion artifacts. However, B1 variation can cause significant problems at high field. In this work, T1 weighted human liver images are acquired using a fast gradient echo sequence and a λ/2 microstrip surface coil on GE whole body 7T scanner. Preliminary data demonstrates the feasibility of human liver imaging at 7 Tesla.
