A Review of Diagnostic Reference Levels in Computed Tomography
Current Medical Imaging Formerly Current Medical Imaging Reviews, 2022: Computed Tomography (CT) scanning generates 3-D images of the inside structures of the body by delivering a comparative radiation dose to the patient. This requires great concern of optimization via establishing Diagnostic Reference Level (DRL). DRL values can be estimated based on reference patient percentiles (such as 90th, 75th, and 50th) dose ...

Mammography Diagnostic Reference Levels (DRLs) in Ghana
Radiography, 2021Diagnostic Reference Levels (DRLs) are essential for optimisation in mammography. A local DRL for screen-film mammography has been established in Ghana but none exists for the digital mammography systems. Furthermore, technological advancement is phasing out the use of screen-film mammography and replacing it with digital mammography systems.

Local Diagnostic Reference Levels in Interventional Radiology
Journal of Medical Imaging and Radiation Sciences, 2020Interventional cardiology procedures, during which live images are acquired, involve exposure to x-rays. The use of fluoroscopy can cause high radiation doses to patients and operators because of the prolonged duration of x-ray emission. For this reason, special attention and constant vigilance represent challenges for commissions and groups of experts

Diagnostic reference levels in interventional radiology
Physics in Medicine and Biology, 2000Following the release of European Directive EU 97/43, radiodiagnostic facilities within the European Union are required to implement a system of patient dose reviews based on comparisons with European, national and local diagnostic reference levels (DRLs). Establishing these levels for typical interventional radiology examinations presents a problem as

Mammography diagnostic reference levels in Western Australia
Physical and Engineering Sciences in Medicine, 2020Mammography dose data has been collected from Western Australian units to establish Diagnostic Reference Levels for the state. Reference levels have been determined for a variety of phantom thicknesses for both full field digital mammography units and digital breast tomosynthesis units.

A local diagnostic reference level for velopharyngeal investigations
The British Journal of Radiology, 2005The purpose of this study was to derive an initial local diagnostic reference level for velopharyngeal investigations carried out as standard radiological practice in the Medical Imaging Department, Queen Victoria Hospital, East Grinstead. This is a specialist video-fluoroscopic radiological technique used to evaluate velopharyngeal dysfunction ...

A contribution to the establishment of diagnostic reference levels in CT
The British Journal of Radiology, 2003CT has become the major source of population exposure to diagnostic X-rays. CT dose index (CTDI) and dose-length product (DLP) have been proposed as the appropriate dose quantities for the establishment of diagnostic reference levels for optimizing patient exposure.

Provision of Italian diagnostic reference levels for diagnostic and interventional radiology
La radiologia medica, 2020The diagnostic reference level (DRL) is a useful tool for the optimisation of medical exposures. Thus, a Working Party coordinated by the Italian National Institute of Health and the National Workers Compensation Authority has been formed to provide Italian DRLs, for both diagnostic and interventional procedures, to be used as appropriate for the ...

Diagnostic reference levels for mammography in BreastScreen Queensland
Australasian Physical & Engineering Sciences in Medicine, 2011Diagnostic reference levels assist in the optimisation of radiation exposure parameters within a medical imaging facility. As no Australian DRLs currently exist, radiation doses from mammography in BreastScreen Queensland are analysed. Program-based DRLs of 1.1 and 1.4 mGy are proposed for digital radiography and computed radiography mammography ...

Diagnostic reference levels in pediatric radiology in Austria
European Radiology, 2010Because of the higher sensitivity to radiation in children, optimization plays an essential role in pediatric radiology. Diagnostic reference levels are a helpful tool to optimize patient dose for standard radiographic procedures.A nationwide survey was conducted to determine doses and variation in average dose applied to children for standard X-ray ...
