Abstract
Seven commercially available biliary stents were tested to determine i f they caused any clinically important attenuation of therapeutic radi ation. Attenuation effects were evaluated in models of brachytherapy ( iridium-192 source) and external beam radiation therapy (cobalt-60 sou rce), with use of parameters that mimicked those used in patient treat ment for biliary neoplasms. No stent demonstrated clinically important attenuation or scatter of therapeutic radiation, so local dosimetry w as not affected.
