To deliver optimal radioiodine activity in hemodialyzed patients with thyroid carcinoma, the behavior of radioiodine was followed during six treatments. During hemodialysis, blood activity decreases with a half-life of 3.4 +/- 0.5, (1SD) h. The whole body dose was calculated from the total activity determined during 10 days after 131I administration. A reasonable strategy may consist in delivering 25% of the currently prescribed activity (925 MBq-25 mCi) and to perform the first dialysis session after 24 h to reduce total body irradiation.
