↵* Radiopharmaceutical doses for 70-kg adult. For smaller patients, radiopharmaceutical dose is scaled by patient's weight.
↵† For 99mTc-DMSA and 99mTc-MAG3, weight-based radiopharmaceutical dose was less than prescribed minimum dose for Children's Hospital Boston (7.4 and 37 MBq, respectively). Value in parentheses is effective dose for prescribed minimum dose.
Dosimetry for nuclear medicine procedures is based on data provided by Michael Stabin, Vanderbilt University, except where otherwise noted (‡ICRP Report 80; §ICRP Report 53). Dosimetry for radiographic procedures was provided by Keith Strauss, Children's Hospital Boston.
