Imaging guidance for GP commissioning First published in 1989, The Royal College of Radiologists (RCR) has produced the referral guidelines, Making the best use of clinical radiology services, to help GPs, clinicians, radiologists, radiographers and other healthcare professionals to determine the most appropriate imaging investigation(s) for a wide range of clinical problems. They provide practical guidance based on the best available evidence, together with expert opinion where evidence is lacking or conflicting. The principal objectives of the RCR s guidelines are: To ensure patients have timely and accurate diagnosis by ensuring doctors and referring clinicians have knowledge of the most appropriate imaging investigation or intervention To reduce unnecessary exposure of patients to radiation To assist in the efficient and equitable utilisation of available diagnostic resources. The process for development of the seventh edition of the guidelines (November 2011) has been formally approved under the NHS Evidence Accreditation Scheme. The full resource consists of 330 guidelines designed to assist the clinician in selecting the most appropriate investigation for a given diagnostic or imaging problem. The guidelines are split into 12 sections: Breast disease Musculoskeletal system Cancer Neurological system Chest and cardiovascular system Obstetrics and gynaecology ENT/head and neck Paediatrics Gastrointestinal system Trauma Interventional radiology Urogenital and adrenal. This summary lists the investigations for guidelines which relate to the most common presentations in primary care. This list is based on investigations rather than the clinical problems to facilitate the commissioning process. It is not intended as a GP s substitute for RCR referral guidelines but rather for those commissioning diagnostics wishing to know which essential radiological investigations to commission. The relevant RCR referral guideline is shown, with links to other related UK guidelines. Commissioners may choose to include other specialised investigations, such as MRI shoulder, which are often resource-intensive and usually only undertaken after discussion with the radiologist or in the context of locally agreed protocols. In these referral guidelines, the doses have been grouped into broad bands to help the referrer understand the order of magnitude of radiation dose of the various investigations.
