The Diagnosis of Morphologic Abnormalities of the Human Thyroid Gland by Means of I131

Abstract
A method of using radioactive I for visualization of the frontal profile of the thyroid gland by means of a scintillation counter provided with a scaling circuit with an adjustable printing relay for recording, and doses of carrier-free radioiodine, ranging between 100 and 300 [mu]c, administered orally in capsule form has been descr. It was necessary to have 60 to 80 [mu]c of I131 concentrated in the thyroid gland. Actual outlining procedure was done 24 to 48 hrs. after admn. of the I131 dose. The results of studies recorded in this manner are preserved as a permanent record (Scintigram). Typical examples are presented in the text.
