Adrenal Scintigraphy with ¹³¹I-Adosterol

Summary

A new adrenal scanning agent, Adosterol (¹³¹I-6β-iodomethyl-19-norcholest-5(10)-en-3β-ol) has been evaluated in three female patients with hypercortic-ism. In one case, characterised by recurrent adrenocortical hyperactivity after bilateral adrenalectomy, a remnant of adrenal tissue was detected. In two other cases, the presence of an adrenal tumour could be excluded. The scan made on the 6^th day after the administration of Adosterol was found to be superior in quality to that made on the 13^th day.
