Embedding new technology into clinical ultrasound practice: Is role extension for sonographers the key to improving patient pathways?

MicroUS is a new imaging technique that may have potential to reliably monitor prostate disease and therefore release capacity in MRI departments. Firstly, however, it is essential to identify which healthcare staff may be suitable to learn to use this modality. Based on previous evidence, UK sonographers may be well placed to harness this resource. Currently, there is sparse evidence on the performance of MicroUS for monitoring prostate disease but early findings are encouraging. Although its uptake is increasing, it is believed that only two sites in the UK have MicroUS systems and only one of those uses just sonographers to undertake and interpret this new imaging technique. UK sonographers have a history of role extension dating back several decades and have proven repeatedly that they are reliable and accurate when measured against a gold standard. We explore the background of UK sonographer role extension and postulate that sonographers are best placed to adopt and embed new imaging techniques and technology into routine clinical practice. This is of particular importance given the dearth of ultrasound focussed radiologists in the UK. To effectively introduce challenging new work streams, multi-professional collaboration in imaging, alongside sonographer role extension, will ensure precious resources are maximised thus ensuring optimum patient care. UK sonographers have repeatedly demonstrated reliability in many areas of role extension in various clinical settings. Early data indicate that the adoption of MicroUS for use in prostate disease surveillance may be another role suited to sonographers.
