T1 relaxation times of adipose tissue have often been used to correct for T1 effects in the quantification of liver fat content. These values, however, were derived in healthy lean subjects and may therefore vary from those in obese patients. This work determines T1 relaxation times at 1.5 T in subcutaneous and visceral adipose tissue in morbidly obese subjects and patients with NAFLD. The results showed that the T1 values in adipose tissue of both obese and lean NAFLD patients can be significantly shorter than those in healthy controls.
