Study of Treatment planning for radio-immunotherapy

RIT treatment planning is improve therapy by collecting patient-specific information (such as the activity distribution) before treatment. Its objective maximizes the dose absorbed by the tumor while minimizing the toxicity to normal tissue. To gain good healing effect in RIT, one needs to determine:the quantity and spatial distribution of the administered radionuclide carrier in the patient over time; the absorbed dose in the tumor sites and critical organs based on this distribution; the volume of tumor and critical organs from CT or MRI and appropriately correlated with nuclear medicine imaging techniques. This article conclude and discuse various RIT treatment planning used present and quantitation of activity, volume determination and calculation of absorbed dose that are used in these treatment planning.
