Brown adipose tissue (BAT) is a thermogenic tissue known to be present in human infants, but only recently has it been confirmed in adults using 18F-FDG PET. Reliable identification and spatial mapping methods that can distinguish BAT from white adipose tissue (WAT) would provide investigators with a powerful tool with which to study BATs influence on body metabolism and composition. Using fat-water MRI and 18F-FDG PET, we imaged BAT in a healthy adult human.
