December 2002 Update:

Following a number of comments regarding the timescale for submission of data for the CT dose survey the deadline has been extended. In order to ensure that your responses are included in the first analysis of the data the completed forms should to be sent to Paul Shrimpton at NRPB by the end of January 2003. Any responses submitted after this date will be included in any subsequent analysis so please continue to send them in.

Please don't forget to supply contact details for all data submitted (just in case there are any points for clarification on the forms), although all information will of course be treated in confidence and data from the survey will subsequently be published only in anonymous form.

A Big 'Thank You' to all those who have already submitted data. The response so far has been very encouraging.

Original call for data:

The CT Users Group, in association with the NRPB and ImPACT is conducting a survey of CT practice and patient dose in the UK.

This major survey aims to cover the whole of the UK, all scanner models including single and multi-slice systems, all healthcare sectors, and both adult and paediatric patients. The project has been endorsed by the Department of Health and the professional bodies (IPEM, CoR and RCR).

We plan to collect information on the scanning protocols in common use at CT centres by means of a questionnaire requiring joint completion by radiographers and physicists. The data will be regarded as confidential and the final results of the survey will be published by NRPB in anonymous form so that the performance of individual CT scanners cannot be identified. There will, however, be due acknowledgement of all participating CT centres. The ultimate aim is to set up a long term, sustainable, National CT Patient Dose Database that can be reviewed periodically by NRPB to provide advice to the professional and regulatory bodies on national reference doses for adult and paediatric CT examinations.

PLEASE HELP US NOW - by downloading the questionnaire and arranging for the submission of data from all the scanners with which you are involved.
