We report here the results of a dose evaluation based on information obtained in a 2011 questionnaire as compared with an investigation made in 2007. Briefly, in general radiography, the dose used in most examinations in 2011 was lower than in 2007. However, since the entrance surface dose for chest X-rays showed an increase, there is a need to standardize the taking of digital images to be abl...

Although maximum exposure limits are not listed for radiologic examinations, a study conducted by the United States Government has determined the average values for ten selected radiologic examinations. This study entitled Nationwide Evaluation of X-ray Trends (NEXT) can be used as a guide to determine if your x-ray department meets these criteria. Recommendations are made for the reduction of ...

Objectives: The aim of this study is measurement of entrance surface doses (ESD) for the most routine types of X-ray procedures in radiology centers as part of ongoing d...

The current status of the problems and challenges facing the system of admission to the undergraduate programmes in centrally funded science and technology institutions is discussed with respect to the reforms that this system was subjected to in 2012–2013, and the suggestions contained in the recent report of the ‘Committee of Eminent Persons’ (CEP). The consequences of the changes that were i...

Introduction Given the fact that children are more sensitive to radiation, compared to adults, special attention needs to be paid to radiation protection in pediatric radiology. Diagnostic reference level (DRL) has been defined to be employed as a practical tool for examining the overall performance of a radiological center in terms of patient dose among a series of similar equipments in an are...

This work aimed to standardize and state” the insufficiencies outlined variation in image quality, among some hospitals Sudan for a common specific radiologic examinations. A subjective evaluation of 1,103 reproductions from “363 special procedures including Intravenous Urography (IVU), Hysterosalpingography (HSG), GIT barium studies” Micturating Cystourethrography (MCUG), Ent...
