Abstract
The adrenal scintiphotography is performed on the 7th, 8th and 9th day following the intravenous administration of 1 mCi of 131I-adosterol by Nuclear-Chicago Pho Gamma III or Ohio-Nuclear 100 scinticamera. The cases subjected to study are 10 cases of primary aldosteronism and 10 suspected, 4 cases of Cushing syndrome and 3 suspected, and 2 cases of pheochromocytoma and 11 suspected.
The lesions are clearly demonstrated as an hot spot, in all operatively verified cases of primary aldosteronism, Cushing syndrome, and pheochromocytoma respectively.
The normal adrenal glands, are either normally visualized or not visualized. In the primary aldosteronism, the lesions visualized are ranged in the size of 13 to 27 mm. In the Cushing syndrome, the lesions visualized are ranged in the size of 20 to 38 mm. In the pheochromocytoma, the lesions visualized are 40 mm in diameter.
The adrenal scintiphotographic study is useful to detect the lesions and/or to determine the side of lesion before the angiographic examination.
