UNLABELLED The objective of this study was to devise and implement a Europe-wide study on referral guidelines for radiological imaging in the EU Member States in order to identify potential major issues, important differences between Member States and good practices. A web-based survey was used to assess the availability of imaging referral guidelines, development methodology and preferences fo...

In the UK, as elsewhere, there is potential to improve how radiological challenges are addressed through improvement in, or development of, a strong radiation protection (RP) safety culture. In preliminary work in the UK, two areas have been identified as having a strong influence on UK society: the healthcare and nuclear industry sectors. Each has specific challenges, but with many overlapping...
Introduction: Coronary angiography (CA) is an interventional diagnostic procedure to assess cardiovascular disease. CA is performed using dedicated fluoroscopic systems equipped with either flat detector or image intensifier. There is an increase in the number of CA annually. Reducing the radiation exposure in the CA is essential, especially due to high fluoroscopy time. In ord...
background: exposure to ionizing radiation results in genotoxicity and the unrepaired lesions in cellular dna results in cell cycle arrest, reproductive death, interphase death, division delay, chromosome aberrations, mutations, etc. leading to the intensive destruction of cells and violation of their proliferative capacity there by adversely affecting the mammalian system. since ionizing radia...
Background: The number of interventional cardiology procedures performed has increased rapidly over the past years. While these procedures help physicians avoid using highly complicated invasive methods, it usually leads to high levels of exposure to ionizing radiation of both patients and cardiologist. The dose received by the cardiologist during interventional cardiology procedures is determi...
background: increasing the x-ray focus to film distance (ffd) has been advocated as an effective method to reduce the patients’ radiation dose. the aim of this study was to investigate the efficacy of this technique in patients' dose and image quality in pediatric chest x-ray.material and methods: sixty pediatric patients were x-ray imaged at ffds of 100 and 130 cm. dose measurements were ...
abstract introduction: recently uses of medium and high energy x-rays has been increased in iran and radiotherapy centers along with a variety of accelerators have been installed in some provinces. in the other hand there is no sufficient skill in designing and making radiotherapy treatment rooms. this study was conducted to evaluate the efficacy of different mixtures of barite concrete for sh...
