• Sharon Addison

  Sharon trained at the University of the West of England (UWE) between 1993 and 1996, gaining experience at Gloucester, Bristol and Plymouth hospitals. The first three years of Sharon’s career was spent at the Princess Royal Hospital in Telford, where she gained a wide range of radiographic experience, including CT. In 1999, Sharon relocated to the Royal Devon and Exeter Hospital, in Exeter, where she still is based.

  Sharon has spent 19 years in CT and MRI, most of them full time, which has allowed her to gain a profound clinical competence in many areas of CT. Over the last eight years Sharon has been actively involved in many aspects of the department, her expertise lies within CT, however she also has a wealth of MRI knowledge too. One of Sharon’s main roles has been implementing CT applications on all three departmental CT scanners. This knowledge has extended to other new sites covered by the department, this aided keeping the CT service running over the pandemic. She has been actively employed in establishing a safe quality service on the CT scanners at the newly developed CDH Exeter Nightingale.

  Working with external suppliers to build protocols and train radiographers in advance techniques. During her time at Exeter, she set up a study day for the cardiology and radiology consultants for CT cardiac scanning, with support from a CT manufacturer. The day was based around how to adapt CT scans for patients when they are in arrhythmias and how to improve image quality for technically challenging scans. A few years ago, when the department upgraded a CT scanner, Sharon had the opportunity to use her expertise to visit other hospitals critically evaluating CT scanners from a variety of manufacturers.

  Her recommendations allowed the selection of a CT scanner that suited the departments requirements and budget. In 2021, Sharon returned to UWE to complete her post graduate qualification in CT, this under pinned her knowledge of CT and ignited a passion for striving for the best for patients, her colleagues, and the future of the service.
