Internal Radiation Dosimetry in Radionuclide Therapy

Radionuclide therapy has been continued for treatment of incurable diseases for past decades. Relevant evaluation of absorbed dose in radionuclide therapy is important to predict treatment output and essential for making treatment planning to prevent unexpected radiation toxicity. Many scientists in the field related with nuclear medicine have made effort to evolve concept and technique for internal radiation dosimetry. In this review, basic concept of internal radiation dosimetry is described and recent progress in method for dosimetry is introduced. (Nucl Med Mol Imaging 2006;40(2):120-126
