Abstract
In thyroid scintigraphy, if the thyroid131I uptake measurement is made simultaneously with the scintigram of the thyroid gland using a pinhole scinticamera, it would be very convenient for us. However, the problem is whether correct results can be obtained or not. Then, some experiment has been carried out. The results obtained were compared with the routine thyroid uptake tests (GRINS technique) . The values of uptake were in general low compared with the ORINS technique, when a point source like a capsule is used as a standard source. It is recommended that the thyroid 131I uptake measurement is made separately from the scintigraphy by 20-25 cm distance method, or used a standard source similar to a patient's thyroid.
