Diagnostic Reference Levels

American Journal of Roentgenology, 2015
W1 demand [4]. Dose limits apply to occupational and public exposure, not to exposure of patients (medical exposure), because limits may compromise patient care. Diagnostic reference levels are used as a trigger to identify those facilities using unusually high doses in a specified radiologic procedure, for which optimization actions are needed.

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, 2021
Diagnostic 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.

Diagnostic reference levels in interventional radiology

Physics in Medicine and Biology, 2000
Following 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

Local Diagnostic Reference Levels in Interventional Radiology

Journal of Medical Imaging and Radiation Sciences, 2020
Interventional 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

A local diagnostic reference level for velopharyngeal investigations

The British Journal of Radiology, 2005
The 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 ...

Mammography diagnostic reference levels in Western Australia

Physical and Engineering Sciences in Medicine, 2020
Mammography 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 contribution to the establishment of diagnostic reference levels in CT

The British Journal of Radiology, 2003
CT 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, 2020
The 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 ...
