Abstract
Radiological imaging in children has been increasingly used over the last two decades. Children are at higher risk compared to adults due to the detrimental effects of radiation. ICRP recommended to establish paediatric DRLs, including high-dose examinations and procedures, such as CT studies and interventional radiology procedures. However, only a few European countries have established paediatric DRLs, mostly for a limited set of examinations. The existing paediatric DRLs are often adopted from old European Commission recommendations or from rarely updated surveys performed by other countries. Furthermore, the lack of a standardized methodology for establishing DRLs in children prevents the comparison among those already available.Recently, an EC project on new European Guidelines for DRLs in Paediatric Imaging (PiDRL) was awarded to a consortium lead by ESR with the involvement of ESPR, EFRS, EFOMP, and STUK. This project resulted in a series of recommendations concerning the methods to establish new DRLs in children. These recommendations include the definition of local, national, and European DRLs, the set of examinations for which DRLs should be established, grouping of children, dosimetric parameters, and instructions on how to make good use of DRLs. The PiDRL guidelines also provide a set of European DRLs (EDRLs), based on the median value of the distribution of national DRLs for a defined clinical imaging task surveyed for standardised patient groupings. These EDRLs provide an interim solution for countries without national DRLs (NDRLs), until such NDRLs become available.Future steps to be taken are the establishment and use of new EDRLs according to the PiDRL recommendations. The involvement and joint efforts of authoritative bodies, scientific societies, and stakeholders are pivotal to this aim.http://www.eurosafeimaging.org/wp/wp-content/uploads/2014/02/European-Guidelines-on-DRLs-for-Paediatric-Imaging_Revised_18-July-2016_clean.pdf.
