Evaluation of PERSH Criteria to Avoid Unnecessary Chest X-ray in Patients with Blunt Chest Trauma: A Qualitative Study
Background: Chest X-rays (CXRs) are traditionally performed to determine intra-thoracic injuries in all blunt chest trauma patients in Shahid Bahonar hospital in Kerman. As there are some disadvantages upon CXR and radiation exposure, therefore, this study aimed to evaluate the role of CXR in the diagnosis of intra-thoracic injuries caused by any blunt chest trauma. Me...

متن کاملPatient effective dose evaluation for chest X-ray examination in three digital radiography centers
Background: The radiation doses resulting from diagnostic X-ray examinations are routinely measured in terms of entrance surface dose (ESD) and effective dose (ED). In this study, for the purpose of radiation protection, the radiation doses received from Digital chest X-ray examination were evaluated in terms of ESD and ED. Material and Methods: The ED was calculated by using the MCNP ...
متن کاملAnalysis on X-Ray Parameters of Exposure by Measuring X-Ray Tube Voltage and Time of Exposure
---------------------------------------------------------------ABSTRACT-----------------------------------------------------One of the typical human diagnostic techniques is x-ray. The x-ray examination depends on the range of radiation given to the subject. The radiation from the xray depends primarily upon the x-ray tube current (mA) tube voltage (kVp) and exposure time (s). These parameters ...
متن کاملChest x-ray findings on pyrophyllitosis.
An outline of the chest X-ray findings on pyrophyllitosis was described in terms of working environments and its length of term in the dust. It was clarified that in pyrophyllitosis granular shadows were distributed in the upper and middle lung :fields, which used to indicate an accretion trend at an early stage. A fast development of :fibrosis in the lung was also assumed, from which standpoin...
