  1. NC, not calculated since two NTA and two MAG3 patients received high and low amounts of tracer activity, respectively
  2. Patient 12 withdrew from the study prior to tracer injection
  3. NA, not available
  4. *Voiding volumes are not comparable since the patient voided prior to the completion of an acquisition
