Introduction: There are many ways to treat cancer and pain relief. One of the methods is radiopharmaceutical therapy. Indium 111-rituximab contains the radioisotope indium-111 and rituximab. The Indium-111, after decay, emits gamma rays with energies of 245 KeV and 171 KeV, and beta-radiation of 26 KeV. In this study, the absorbed dose of 111In-Rituximab in human body was calcu...

A 62-year-old man underwent radiotherapy to the left upper chest for treatment of Pancoast syndrome on a background of previous coronary artery bypass grafting 12 years earlier. Within 1 year, he developed significant stenoses of both the left internal mammary artery (LIMA) graft and ostial left vertebral artery, presumably related to therapeutic radiation exposure. Initially diagnosed using co...

Recent global radiation fears reflect the urgent need for a new modality that can simply determine if people are in a radiation risk of developing cancer and other illnesses. Ultraviolet (UV) radiation has been thought to be the major risk factor for most skin cancers. Although various biomarkers derived from the responses of human cells have been revealed, detection of these biomarkers is cumb...

Following the Fukushima nuclear power plant disaster, assessment of internal radiation exposure was indispensable to predict radiation-related health threats to residents of neighboring areas. Although many evaluations of internal radiation in residents living north and west of the crippled Fukushima nuclear power plant are available, there is little information on residents living in areas sou...

The effects of ionizing radiation on Arabidopsis thaliana were investigated using 6 MV x-rays produced by a linear accelerator. Photosynthesis and respiration rates, chlorophyll fluorescence (fv/fm ratio and yield), plant height, total leaf area, stem mass, leaf mass, and above-ground biomass were measured to evaluate both physiological and physical impacts of ionizing radiation. The statistica...

AIMS To determine the feasibility and efficacy of 3-fraction stereotactic body radiation therapy for isolated colorectal cancer liver metastases. MATERIALS AND METHODS Ten patients with isolated inoperable liver metastasis from colorectal cancer with progression after salvage chemotherapy underwent stereotactic body radiation therapy. Follow-up was 7-49 months (median, 12). Six patients had a...

PURPOSE To present the spectrum of CT and MR findings of glomus tumors of the head and neck successfully treated with radiation therapy. METHODS The patient charts and all CT and MR studies of 24 patients (25 tumors) who had been successfully treated with radiation therapy were retrospectively reviewed. Eighteen patients had pre- and posttreatment imaging studies. Tumor size, internal morphol...

Introduction: Breast cancer is one of the most common known cancers in women all around the world. It is the most common cause of death in women after lung cancer. Radiotherapy is a method for therapy of cancer in which certain dose of high energy radiations is used to destruct cancer cells. Radiotherapy is designed so that radiation of eartain does to the target area in body i...

OBJECTIVES The aim of this study was to determine whether high-dose radioactive iodine (Na(131)I) outpatient treatment of patients with thyroid carcinoma is a pragmatically safe approach, particularly for the safety of caregivers. METHODS A total of 79 patients completed the radiation-safety questionnaires prior to receiving high-dose radioactive iodine treatment. The questionnaire studied th...
