1. Radioiodine Therapy of Hyperthyroidism - Simplified patient-specific absorbed dose planning
Sammanfattning : Radioiodine therapy of hyperthyroidism is the most frequently performed radiopharmaceutical therapy. To calculate the activity of 131-I to be administered for giving a certain absorbed dose to the thyroid, the mass of the thyroid and the individual biokinetic data, normally in the form of uptake and biologic half-time, have to be determined.

2. Image Processing for Quantitative Scintillation-Camera Imaging. Application to Radionuclide Therapy
Sammanfattning : Individual-based determinations of the absorbed dose in radionuclide therapy largely rely on absolute measurement of the activity distribution and its redistribution over time. Scintillation-camera imaging is the most commonly employed measuring technique, applied in planar or SPECT mode, sometimes in combination with structural images from CT. LÄS MER
3. Systemic effects after ionizing radiation exposure: Genome-wide transcriptional analysis of mouse normal tissues exposed to (211)At, (131)I, or 4 MV photon beam
Sammanfattning : The radionuclides 131I and 211At are used or proposed for a variety of cancer treatments. Both radiohalogens exhibit considerable uptake in the thyroid gland and–to a lower degree–in various other tissues if they are unbound or released from a cancer-targeting agent. LÄS MER
4. Iodine status and iodine pool an a small community in western Sweden
Sammanfattning : Iodine is essential in the synthesis of the vital hormones of the thyroid gland. On a worldwide basis, iodine deficiency is the global most important cause of thyroid disease. LÄS MER
