摘要：

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