Overview

Rhenium-188 perrhenate is a radiopharmaceutical agent consisting of the radioactive isotope rhenium-188 in its perrhenate form. It is a beta-emitting radionuclide with a physical half-life of approximately 16.9-17 hours and a gamma emission at 155 keV, which allows for both therapeutic applications and scintigraphic imaging (theranostics). The agent is typically produced via elution from a tungsten-188/rhenium-188 generator system. Its mechanism of action involves the delivery of localized beta radiation to target tissues, which induces DNA damage, cell cycle arrest, and apoptosis. Clinical investigations have focused on its use for the palliation of metastatic bone pain, the treatment of unresectable hepatocellular carcinoma (often via transarterial radioembolization), and the management of skin keloids.
