1. Adrenal scintigram was performed for 4 patients with Cushing's syndrome due to ACTH excess, 4 patients with Cushing's syndrome due to unilateral adrenal adenoma, 7 patients with primary aldosteronism, 2 patients with pheochromocytoma and 3 patients with other hypertension, and selective adrenal venography was performed for 12 patients of them. 2. Preoperative determination of the site of the adrenal tumor was made in 6 of 13 patients by PRP, 7 of 9 patients by selective adrenal venography and all of 13 patients by adrenal scintigram, so that adrenal scintigram was proved to be very valuable. 3. It was successful ^+o make early diagnosis for the site of small aldosterone-producing tumor within 1cm in diameter 2 to 4 days after intravenous administration of the tracer dose of 0.3 to 0.4 mCi of ^<131>I-6β-iodomethyl-19-nor-cholest-5(10)-en-3β-ol (^<181><I>-Adosterol) by means of an Gamma camera, aided by computer processing, i.e., subtraction, smoothing, leveling, associated with liver scan with ^<99m>Tc-phytate on the same position. 4. Selective adrenal venography should be performed, unless PRP and adrenal scintigram were able to diagnose the tumor site.
