Hepatobiliary clearance of intravenous Tc-99m pertechnetate

Clin Nucl Med. 1995 Nov;20(11):962-4. doi: 10.1097/00003072-199511000-00002.

Abstract

The normal biodistribution of Tc-99m pertechnetate includes the thyroid gland, salivary glands, choroid plexus, and gastric mucosa. The primary route of excretion is through renal clearance. The authors describe two cases in which hepatobiliary excretion of intravenously administered Tc-99m pertechnetate was observed during scanning for Meckel's diverticulum as a possible source of gastrointestinal bleeding.
