Abstract
The 20 min 99mTechnetium (99mTc) pertechnetate uptake in the thyroid gland has been investigated in 144 patients and compared with the 24 h 131I-uptake. The diagnostic values in 39 patients with hyperthyroidism was found to be the same with both tests whereas the 24 h 131I-uptake gave a better discrimination between the controls and 13 hypothyroid patients than the 20 min 99mTc-uptake. There was no significant difference in the prognostic value of T3 suppression of the 20 min 99mTc-uptake and the 24 h 131I-uptake in 31 patients receiving long-term antithyroid treatment. The 20 min 99mTc-uptake offers several advantages as compared with the 131I-uptake especially a very low radiation dose and less time consumption.Keywords
