Cancer cachexia, a multifactorial wasting syndrome, affects up to 50% of cancer patients and is a major cause of morbidity and mortality. Proton density fat fraction (PDFF) mapping based on a multi-echo gradient echo acquisition enables spatially-resolved fat quantification and can help characterize tissue changes during the course of cancer cachexia. This study investigates changes in volume and PDFF metrics of adipose tissue induced by weight loss in cancer cachexia.
