Summary
The situation in Italy regarding radiation dose to patients undergoing Multidetector row Computed Tomography (MDCT) scans is unclear despite Italian law require that each centre check the Reference Dose Level (RDL) every two years. RDL in CT were first suggested in a document of 1998 published by the European Commission (EUR16262/1998) based on the results of an older survey in the UK from the late 1980s. Those RDLs, expressed in terms of Computed Tomography Dose Index (CTDI) and Dose Length Product (DLP), are reported in the Italian law (D.Lgs.187/00). However, in Italy there is no governmental authority comparable to the UK's National Radiological Protection Board, deputed to dose evaluation and protection.
An overview of the Italian situation is relevant in order to know the actual dose levels for MDCT administered to patients both adults and paediatrics.
