Good guidelines build the best available evidence into the decision-making process and are there to help make the right choice and for reference when the referrer might be in doubt. The right radiological investigation will always obtain maximum information with the minimum of radiation, inform clinical management, reassure the patient and add confidence to the clinician’s diagnosis. The wrong investigation will not provide the best information – and it may add unnecessarily to patient irradiation. This edition of the guidelines contains many new features, which reflect recent changes in the delivery of radiological investigations.

Improved format, easier access

To make it even easier to find the information you need, with the eighth edition, the online content in iRefer was completely restructured. You’ll find improved consistency, more clarity and purpose-designed online content. Improvements include:

  • Personalise and build your own MyRefer – curate your own lists of guidelines to best suit your practice
  • Improved search functionality – you can search by specialty or modality, key word or radiology information system (RIS) code within each section – Adults or Paediatrics
  • Refreshed page layout – making the text clearer and easier to read.

Key references

Inclusion of key evidence and relevant related guidance from organisations such as The Royal College of Radiologists, the National Institute for Health and Care Excellence, the Scottish Intercollegiate Guidelines Network and the American College of Radiology which will help with reinforcing the imaging advice or providing alternative clinical pathways when imaging is unhelpful.
