Background: Chest CT is a commonly used examination for the diagnosis of lung diseases, but a breast within the scanned field is nearly never the organ of interest.Objective: The purpose of this study is to compare the female breast and lung doses using split and standard protocols in chest CT scanning.Materials and Methods: The sliced chest and breast female phantoms were used. CT exams were p...
Background: Pneumothorax may be associated with penetrating or blunt chest traumas' that need early diagnosis and treatment. Today the diagnosis modalities are CXR and CT-Scan that are not suitable for unstable patients. Chest sonography can be a fast diagnostic method at patient bedside. The purpose of this study was to evaluate the accuracy of bedside ultrasonography in diagnosis of pneumotho...
Background: Medical X-rays are the largest man-made source of public exposure to ionizing radiation. While the benefits of Computed Tomography (CT) are well known in accurate diagnosis, those benefits are not risk-free. CT is a device with higher patient dose in comparison with other conventional radiation procedures. Objective: This study is aimed at evaluating radiation dose to patients from ...
Background: Patient radiation doses from computed tomography (CT) are increasing due to the number of CT examinations performed every day. The aim of this study was assess and evaluate patient radiation doses for adult’s common CT examinations to derive local diagnostic guidance levels for common CT examinations. Materials and Methods: Volume and weighted computed tomography dose index (C...

Background and Objectives: The radiation protection of patients in CT examinations is important due to its wide application and high contribution in collective dose of public, and its radiation effects. The purpose of this study was to estimate the mean patient dose indices in chest and abdomen/pelvic examinations as the first step in patient radiation protection process. Materials and Methods...
