Περίληψη:
This review presents basic information on the dosimetric quantities used
in medical imaging for reporting patient doses and establishing
diagnostic reference levels. The proper use of the radiation protection
quantity “effective dose” to compare doses delivered by different
radiological procedures and different imaging modalities with its
uncertainties and limitations, is summarised. The estimates of
population doses required by the European Directive on Basic Safety
Standards is commented on. Referrers and radiologists should be familiar
with the dose quantities to inform patients about radiation risks and
benefits. The application of effective dose on the cumulative doses from
recurrent imaging procedures is also discussed. Patient summary: Basic
information on the measurement units (dosimetric quantities) used in
medical imaging for reporting radiation doses should be understandable
to patients. The Working Group on “Dosimetry for imaging in clinical
practice” recommended that a brief explanation on the used dosimetric
quantities and units included in the examination imaging report, should
be available for patients. The use of the quantity “effective dose”
to compare doses to which patients are exposed to from different
radiological procedures and its uncertainties and limitations, should
also be explained in plain language. This is also relevant for the
dialog on to the cumulative doses from recurrent imaging procedures. The
paper summarises these concepts, including the need to estimate the
population doses required by the European Directive on Basic Safety
Standards. Referrers and radiologists should be familiar with the dose
quantities to inform patients about radiation risks and benefits.
