Optimization of Bremsstrahlung imaging in Yttrium internal radiation therapy
Introduction: Treatment efficacy of radiation therapy using Yttrium-90 radionuclide is evaluated by the bremsstrahlung SPECT imaging following radiation therapy. The radioisotopic images have the ability to provide reliable activity map of 90Y distribution. But these images have a low quantitative accuracy in the 90Y bremsstrahlung SPECT imaging, therefore the optimization of...
متن کاملSelective Internal Radiation Therapy (SIRT) as Conversion Therapy for Unresectable Primary Liver Malignancies.
BACKGROUND Many patients with primary liver cancers are not candidates for surgery, and systemic therapies are seldom effective. Selective internal radiation therapy (SIRT) has been shown to obtain partial and even complete response in unresectable primary tumors. As a "side effect", SIRT can induce contra-lateral liver hypertrophy. Tumor response to SIRT can be sufficient to allow disengagemen...

متن کاملOutcomes and Predictors of Toxicity after Selective Internal Radiation Therapy Using Yttrium-90 Resin Microspheres for Unresectable Hepatocellular Carcinoma
PURPOSE We sought to report outcomes and toxicity in patients with hepatocellular carcinoma (HCC) who received resin yttrium-90 selective internal radiation therapy ((90)Y-SIRT) and to identify factors associated with declining liver function. METHODS Patients treated with (90)Y-SIRT were retrospectively evaluated. Radiographic response was assessed using RECIST 1.1. Median liver progression-...
متن کاملDramatic Response of a Large, 10 Cm Hepatocellular Carcinoma to Monotherapy with Yttrium-90 Based Selective Internal Radiation Therapy
Hepatocellular carcinoma (HCC) is predominantly diagnosed in advanced stages and not amenable to surgical resection and transplantation. Systemic therapies have had a limited efficacy in treating HCC. Although HCC is a radiosensitive tumor, treatments with external-beam radiation are limited by radiosensitivity of normal liver tissue and surrounding organs-at-risk, i.e. bowel, stomach, and kidn...
