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.

Further study details as provided by University of Palermo:

Primary Outcome Measures:
  • MDCT dose survey for the assessment of CT dose in the Italian population. [ Time Frame: One year ] [ Designated as safety issue: Yes ]
    MDCT procedure should be tailored to meet the needs of individual patient, in the mean time dose parameters should be taken in account. In-depth knowledge of patient dose levels may stimulate local programmes of dose reduction and raise radiologist awareness of MDCT in terms of dose and image quality optimization. Dose data arising from the survey may contribute to optimizing single centre standard examination protocols, monitoring CT practice and hopefully stimulate a critical review of every day CT practice.

Secondary Outcome Measures:
  • Reduction dose in MDCT in everyday practice [ Time Frame: Up to two years ] [ Designated as safety issue: Yes ]
    The survey should provide essential data on dose and techniques to facilitate further initiatives in the optimization of patient protection in MDCT. The availability of a database could be useful for on going collation of local survey data as the basis for further periodic reviews of practice and timely revision of national references doses. Hopefully this project will make radiologists aware in determining and applying correct criteria for dose reduction.
