title: Exercise acutely increases renal transit time of Tc-99m mercaptoacetyltriglycine (MAG3) in a post-liver transplant patient.
abstract: This case demonstrates the effect of exercise on the clearance of Tc-99m MAG3 in a patient with renal insufficiency status post-liver transplant. Even after furosemide administration, the tracer was retained in the kidneys after exercise. This is in contrast to normal clearance demonstrated on a baseline study performed 3 days previously.
