"Renal nuclear medicine study combines serial planar images and a renogram. Early frames at 3 seconds per frame show tracer signal in the right kidney. Later frames at 120 seconds per frame show signal in the kidney and urinary bladder. The renogram plots counts over time for the right kidney and bladder, with the kidney curve peaking early and then declining to a plateau. The tracer is not identified."
