Prospective Evaluation of Renal Allograft Dysfunction with ^99m Technetium-Diethylenetriaminepentaacetic Acid Renal Scans

A prospective, single-blinded study was done to determine the ability of serial 99mtechnetium-diethylenetriaminepentaacetic acid scans to diagnose renal allograft rejection. Among 28 transplant recipients 111 renal scans were obtained 1 day postoperatively and every 3 to 4 days thereafter for 3 weeks in all patients retaining an allograft. Computer-generated time-activity blood flow curves were analyzed semiquantitatively for the 1) interval...
