background: intraoral radiographies are the most frequent x-ray examinations in humans. according to international commission on radiation protection (icrp) recommendations, the selection of a diagnostic reference level (drl) should be specific to a country or region. critica l organs such as thyroid gland are exposed to x-rays in intraoral radiography and these exposures should be kept as low ...

BACKGROUND The most efficient application of ionizing radiation is serving medical purposes and using this radiation has caused people to learn that artificial sources of radiation exposure among these resources can be of highest exposure rate. OBIECTIVE The present study is aimed at initially establishing a baseline for local-reference dose level in Mazandaran, Iran in 12 projections of the ...

Objective: The aim of this study was two fold. To determine the diagnostic reference level (D.R.L.) dose of radiation during dynamic hip screw (D.H.S.) fixation and, to audit the orthopaedic department against this standard. Methods and Materials: A retrospective analysis of 112 consecutive patients between 31st December 2002 and the 6th July 2003, at Darenth Valley Hospital, Dartford, under go...

Background Given the fact that children are more sensitive to ionizing radiation than adults, with an increased risk of developing radiation-induced cancer, special care should be taken when they undergo X-ray examinations. The main aim of the current study was to determine Entrance Surface Dose (ESD) to pediatric patients arising from routine x-ray examination in the Radiology Department of Ji...

Introduction: Diagnostic reference level (DRL) is a useful tool for the promotion of optimization. The national DRLs (NDRLs) are useful, brief, and robust guidelines for optimizing radiation protection in a country. The aim of this study was to extract the local DRLs (LDRLs) for some common radiologic examination in Sabzevar county. Materials and Methods: There are eight radiology departments ...

The aim of this work is to present the functionalities and first results of an automatic system on quality control and patient dosimetry for diagnostic radiology, and its application to computed tomography (CT) in a big university hospital. The system is directly connected to the PACS (Picture Archive an Communication System) of the hospital and extracts useful information contained in the DICO...

background: computed tomography (ct) is main contributor of population dose from diagnostic x-ray examinations. children are more radiosensitive than adults, thus optimization of ct examination in these patients is essential. the purpose of this study was to evaluate dose delivered to pediatric patients’ undergoing ct examination of the common examinations and also establishing local diagnostic...

Introduction The purpose was to determine if an age based, local diagnostic reference level for paediatric skeletal surveys could be established using retrospective data. Methods All children below two years of referred a primary survey as result suspected physical abuse during 2017 or 2018 (n = 45) were retrospectively included from large Danish university hospital. protocol total 33 images.
