Radiation dose associated with common computed tomography examinations and the associated lifetime attributable risk of cancer.
BACKGROUND Use of computed tomography (CT) for diagnostic evaluation has increased dramatically over the past 2 decades. Even though CT is associated with substantially higher radiation exposure than conventional radiography, typical doses are not known. We sought to estimate the radiation dose associated with common CT studies in clinical practice and quantify the potential cancer risk associa...
متن کاملPatient-Specific Radiation Dose and Cancer Risk in Computed Tomography Examinations in Ondo, Nigeria
Introduction: The dose in computed tomography (CT) often approach or exceed the optimum levels, thereby increasing the probability of cancer induction. With wide application of this diagnostic test, it is expedient to determine the effective dose (ED) for each patient to estimate their cancer risk. This study was conducted to investigate the patient-specific dose (PSD) and cancer risk in CT exa...
متن کاملEstimating risk of cancer associated with radiation exposure from 64-slice computed tomography coronary angiography.
CONTEXT Computed tomography coronary angiography (CTCA) has become a common diagnostic test, yet there are little data on its associated cancer risk. The recent Biological Effects of Ionizing Radiation (BEIR) VII Phase 2 report provides a framework for estimating lifetime attributable risk (LAR) of cancer incidence associated with radiation exposure from a CTCA study, using the most current dat...
متن کاملExcess lifetime cancer mortality risk attributable to radiation exposure from computed tomography examinations in children.
BACKGROUND The use of computed tomography in Israel has been growing rapidly during recent decades. The major drawback of this important technology is the exposure to ionizing radiation, especially among children who have increased organ radiosensitivity and a long lifetime to potentially develop radiation-related cancer. OBJECTIVE To estimate the number of excess lifetime cancer deaths relat...
متن کاملOrgan Dose and Attributable Cancer Risk in Lung Cancer Screening with Low-Dose Computed Tomography
PURPOSE Lung cancer screening with CT has been recently recommended for decreasing lung cancer mortality. The radiation dose of CT, however, must be kept as low as reasonably achievable for reducing potential stochastic risks from ionizing radiation. The purpose of this study was to calculate individual patients' lung doses and to estimate cancer risks in low-dose CT (LDCT) in comparison with a...
