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.
