Estimating the Radiation-Induced Cancer Risks in Pediatric Computed Tomography
Introduction One of the central questions in radiological protection is the magnitude of the risks from low doses of radiation, related to the justification and optimization of the diagnostic medical exposures. Therefore, the aim of this study was to estimate the cancer incidence and mortality risks in children of different ages, sizes, and ethnicities undergoing computed tomography examination...
متن کاملQuantitative Computed Tomography
Computed Tomography (CT) is a wide-spread medical imaging modality. Traditional CT yields information on a patient’s anatomy in form of slice images or volume data. Hounsfield Units (HU) are used to quantify the imaged tissue properties. Due to the polychromatic nature of X-rays in CT, the HU values for a specific tissue depend on its density and composition but also on CT system parameters and...
متن کاملAortic Coarctation: Evaluation with Computed Tomography Angiography in Pediatric Patients
Background: Aortic coarctation is a congenital narrowing of the aorta. Computed tomography angiography is used to detect aortic coarctation and determine its extent and severity. Objective: To assess pediatric aortic coarctation by computed tomography (CT) angiography. Material and Methods: This study included eighteen patients (10 males and 8 females) who were clinically diagnosed to have coar...
متن کاملEstimating and comparing the radiation cancer risk from cone-beam computed tomography and panoramic radiography in pediatric and adult patients
Background: This study aimed to estimate and compare the absorbed dose, lifetime cancer risk and mortalities due to cone-beam computed tomography (CBCT) and panoramic examinations on patients. Materials and Methods: The exposure factors were applied to 332 patients in two age groups (6-10, and ˃18-year-old). The dose-area product (DAP) values were measured for CBCT and panoramic radiographies. ...
متن کاملQuantitative computed tomography in children and adolescents
Methods for quantitative assessment of the skeleton are relevant to the understanding of growth and development during normal childhood and studying the effect of disease and therapy in children with chronic diseases. Dual energy x-ray absorptiometry (DXA) is currently the most widely available and utilised technique in adults and children. The strengths of DXA are: • The technology is widely a...
