About the webinar

Diagnostic reference Levels (DRLs) were introduced by the International Commission on Radiological Protection (ICRP) as a tool to help optimize medical imaging in diagnostic and interventional procedures. This webinar will introduce the general concept of DRLs and will thereafter focus on the concept of clinical DRLs which are based on clinical indications as the main determinants of patient radiation dose rather than the anatomical locations.

Different image quality is needed for different clinical indications of the same anatomical area. Kidney stone evaluation, for instance, can be performed using lower radiation doses than those used in evaluation of appendicitis because detection of high-contrast structures is affected less by high image noise than low contrast structures. Clinical indications dictate the main parameters that affect patient dose from CT such as scanning length, collimation and number of phases. Therefore, DRLs should be specified for a given clinical indication.

The European Commission tender project European study on clinical diagnostic reference levels for X-ray medical imaging (EUCLID) will be briefly presented in the webinar. Also, the webinar will give an introduction to the concept of local DRLs, which are a useful tool for quality control and dose optimisation, in particular in case no national DRLs are available.

Presenter: Prof. John Damilakis, Prof. Guy Frija
