2089-P: Regional Renal Hemodynamics and Fatty Acid Uptake: Effects of Obesity and Weight Loss

Objective: Changes of obesity on renal perfusion and metabolism are poorly understood. Our aims were to evaluate whether obesity increases renal regional hemodynamics and metabolism in vivo, and to determine the effects of weight loss. Methods: 23 morbidly obese and 15 age- and sex-matched nonobese controls were recruited. Renal perfusion and fatty acid uptake (FAU) were measured using PET-CT scanning and [15O]- H2O and...
