Expanding the Concept of Diagnostic Reference Levels to Noise and Dose Reference Levels in CT
American Journal of Roentgenology, 2019 OBJECTIVE. Diagnostic reference levels were developed as guidance for radiation dose in medical imaging and, by inference, diagnostic quality. The objective of this work was to expand the concept of diagnostic reference levels to explicitly include noise of CT examinations to simultaneously target both dose and quality through corresponding reference ...

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.

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.

National diagnostic reference levels: What they are, why we need them and what’s next
Journal of Medical Imaging and Radiation Oncology, 2022Diagnostic reference levels (DRLs) are an optimisation tool for medical imaging procedures using ionising radiation. They give an indication of the expected radiation dose received by an average‐sized patient undergoing a given imaging procedure ...

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 ...

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
