Manufacturers often update parts (e.g., MIRD-237 Rev B). Ensure you are buying the exact version your system requires. to calculate the radiation dose delivered to target organs
MIRD-237 is a report in the Medical Internal Radiation Dose (MIRD) series produced by the Society of Nuclear Medicine and Molecular Imaging (SNMMI) and the MIRD Committee. It provides methodology, models, and guidance for internal dosimetry associated with radiopharmaceutical therapy (RPT) and diagnostic nuclear medicine. The MIRD reports aim to standardize dose calculation, define terms and symbols, and recommend best practices for estimating radiation dose to organs, tissues, and tumors from administered radiopharmaceuticals.
The MIRD Committee , established by the Society of Nuclear Medicine and Molecular Imaging (SNMMI), revolutionized radiation safety by standardizing internal dosimetry calculations. Before the MIRD formalism, estimating the absorbed dose from a drug circulating inside a patient's body was highly fragmented. The Core MIRD Formula The basic equation to calculate the absorbed dose ( D̄cap D bar ) in a target tissue ( ) from a source tissue ( ) is defined as:
Conclusion MIRD-237 represents a significant step toward routine, patient-specific voxel-based internal dosimetry by formalizing a workflow that connects quantitative imaging with dose-calculation techniques. Its emphasis on uncertainty analysis, validation, and practical imaging corrections makes it a practical reference for clinicians and medical physicists implementing personalized dosimetry for molecular radiotherapies. Continued advances in quantitative imaging, computational methods, and radiobiological modeling will further enhance the clinical utility of the approaches described in MIRD-237.
