Hematologic toxicity limits the radioactivity that may be administered for radiolabeled antibody therapy. This work examines approaches for obtaining biodistribution data and performing dosimetry when the administered antibody is known to bind to a cellular component of blood, bone, or marrow. Marrow dosimetry in this case is more difficult because the kinetics of antibody clearance from the bl...

Introduction: Use of SPECT/CT data is the most accurate method for patient-specific internal dosimetry when isotopes emit single gamma rays. The manual or semi-automatic segmentation of organs is a major obstacle that slows down and limits the patient-specific dosimetry. Using digital phantoms that mimic patient’s anatomy can bypass the segmentation step and facilitate the dosi...

Introduction: Existing phantoms have been constructed based on Caucasian, non-Caucasian and race-specific datasets. According to previous studies made efforts to present Korean- specific phantoms and Chinese female phantom based on CVH dataset due to compare the resulting internal dosimetry with the Caucasian based data showed possible racial difference in human anatomy between ...

Dosimetry for targeted radionuclide therapy is a relatively young field. Although initial work can be traced back to the late 1940s (1), the MIRD Committee formalism that forms the foundation for most current approaches was published in the mid 1970s (2), and the drive for improved dosimetry to meet the requirements of targeted radionuclide therapy did not begin until the 1980s. During this per...

131I-TM-601 is a 36-amino acid peptide, called chlorotoxin (TM-601), derived from scorpion venom labeled with I-131. TM-601 binds a receptor on the surface of tumor cells, and not on normal cells. A single dose of 131I-TM-601 administered intracranially to human xenografted mouse models of glioma has been shown to extend survival up to 269% in multiple studies. 131I-TM-601 is in a multi-center ...
