Current Trends and Limitations in Establishing Diagnostic Reference Levels (DRLs): A Global Perspective

Abstract

Diagnostic Reference Levels (DRLs) are systematic and scientific protocol used for identifying situations where patient's doses are high in diagnostic radiology and nuclear medicine examinations. they are suggested action levels in which a facility can check it's performance and see if achievable doses provide adequate images of diagnostic yield. The study systematically appraise and document the current trends and limitations of diagnostic reference levels and further explains the need to project a way forward by delving and foreseeing into a new concept of acceptable dose which addresses the limitations of diagnostic reference level.
