Clinical magnetization transfer (MT) imaging within the
abdomen has proven to lack sensitivity to detect liver
fibrosis, possibly due to the confounding effect of
lipid infiltration. Here a new method, which aims to
remove the MT dependence on lipid concentration through
integration of IDEAL fat/water separation, is employed.
This study assesses the feasibility of MT-IDEAL imaging
in the abdomen and compares resultant MTR values using
standard MT methods and the MT-IDEAL paradigm. It is
hoped that this will eventually allow for investigation
of pathological changes in fat content and fibrosis
within intra-abdominal organs in a wide range of
diseases.
