Reproducibility of F18‐FDG PET radiomic features for different cervical tumor segmentation methods, gray‐level discretization, and reconstruction algorithms
Site-specific investigations of the role of radiomics in cancer diagnosis and therapy are emerging. We evaluated the reproducibility of radiomic features extracted from 18 Flourine-fluorodeoxyglucose (18 F-FDG) PET images for three parameters: manual versus computer-aided segmentation methods, gray-level discretization, and PET image reconstruction algorithms. Our cohort consisted of pretreatme...
متن کاملEvaluation of radiation protection principles observance in radiology departments of Semnan University of medical sciences
Introduction: Most of people are exposed to ionizing radiation sources during their lifetime including background, cosmic or man-made beams like radiation used in nuclear medicine and radiology. Due to unavoidable use of ionizing radiation in diagnosis and treatment of diseases, designing and correct implementation of radiation protection principles in order to reducing its har...
متن کاملDevelopment of RadRob15, A Robot for Detecting Radioactive Contamination in Nuclear Medicine Departments
Accidental or intentional release of radioactive materials into the living or working environment may cause radioactive contamination. In nuclear medicine departments, radioactive contamination is usually due to radionuclides which emit high energy gamma photons and particles. These radionuclides have a broad range of energies and penetration capabilities. Rapid detection of radioactive contami...
متن کاملEvaluation of knowledge of dentists in Zanjan regarding principles of X-ray protection in 2019
Background and Aims: Radiography is one of the most important para-clinical methods in diagnosing and selecting treatment in dentistry. Due to the potential dangers of X-rays for patients, the professional responsibility of the dentist requires that unnecessary radiographs to be avoided. The aim of this study was to investigate the awareness of dentists in Zanjan about the principles of radiati...
متن کاملUsing the U.S. Geological Survey National Water Quality Laboratory LT-MDL to Evaluate and Analyze Data
A long-term method detection level (LT-MDL) and laboratory reporting level (LRL) are used by the U.S. Geological Survey’s National Water Quality Laboratory (NWQL) when reporting results from most chemical analyses of water samples. Changing to this method provided data users with additional information about their data and often resulted in more reported values in the low concentration range. B...
