Introduction Computed Tomography scans are a very important tool for diagnosis and assessment of response to treatment in the practice of medicine. Ionizing radiation in medical imaging is undoubtedly one of the most powerful diagnostic tools in medicine. Yet, as with all medical interventions, there are potential risks in addition to the clear potential benefits. Materials and Methods Two refe...
متن کاملPatient dose resulting from CT examinations in Yazd, Iran
Background: With the introduction of computed tomography in diagnostic radiology a new and fundamentally different imaging modality has become available. Meanwhile, it is clear that the absorbed doses by the patients during CT were relatively high in comparison with those of other diagnostic radiology techniques. The aim of this survey was to determine the average absorbed dose in Yazd provin...
متن کاملUltra-Low Radiation Dose Renal CT Examinations
These efforts include the development of customized protocols that take into account the patient’s age, body mass and clinical indication. This allows for lower dose scan parameters and targeted scanning to cover only the region of interest and thereby limit oversampling. In addition, new iterative image reconstruction techniques can improve image quality on low dose, higher noise CT scans. As ...
متن کاملAssessment of dose reduction and influence of gantry rotation time in CT abdomen examinations
Background: Worldwide the computed tomography (CT) scanning is recognized as a high radiation dose modality. This article aimed to estimate the radiation dose reduction and radiogenic risks for adult patients undertaking abdominal CT examinations. Materials and Methods: A total of 128 patients were studied using 2, 4, 16 and 64 slice CT scanners. The patients were divided into two categories: t...
