Cancer is considered as one of the fatal diseases, and every year, more than 10.9 million people worldwide are diagnosed with the disease. Mater...
متن کاملDiagnostic uncertainty of isolated skull lesion in prostate cancer- Role of SPECT/CT
Skeletal involvement is the second most common site of metastases after lymph nodal metastases in patients with prostate cancer. The skeletal metastases from prostate cancer are osteoblastic in nature and show increased tracer avidity on the bone scan. Focal tracer avid lesion in skeleton especially in skull requires the careful examination by further investigation. The patients with skull meta...
متن کاملLow-dose CT scan screening for lung cancer: comparison of images and radiation doses between low-dose CT and follow-up standard diagnostic CT
OBJECTIVES This study aim to compare image quality and radiation doses between low-dose CT and follow-up standard diagnostic CT for lung cancer screening. METHODS In a single medical institution, 19 subjects who had been screened for lung cancer by low-dose CT before going through follow-up standard diagnostic CT were randomly selected. Both CT image sets for all subjects were independently e...
متن کاملRadiation induction of cancer of the skin.
Toe induction of epidermal tumors was studied using exposures to 25 kV X-rays with or without subsequent exposures to 12-0-tetradeconyl phorbol-13 acetate (TPA) or ultraviolet radiation (UVR) 280-400 run. Fractionation regimens and total exposure upto 4000R produced no squamous cell carcinomas. When these regimens were followed by TPA an incidence of about 80? was obtained, and an incidence of ...
متن کاملComparison of PET/CT and CT-based tumor delineation and its effects on the radiation treatment planning for non-small cell lung cancer
Introduction: Tumor volume delineation is the most important step in the radiation treatment planning. In this study the impact of PET/CT data on the tumor delineation precision of non-small cell lung cancer (NSCLC) was investigated. Methods: PET/CT images of 20 patients with primary NSCLC were obtained and imported to the treatment planning system for im...
