Staff in the A&E department at Glasgow Royal Infirmary are finding the metal artefact reduction algorithm on their CT system enables them to gain clearer imaging to assist more confident and faster diagnosis.
The SEMAR application on the Canon Medical Aquilion Prime SP CT eliminates the distortion of metallic artefacts inside patients generated from items such as orthopaedic plates or screws, medically implanted coils or clips, or fragments from trauma incidents. It automatically removes the streaks of distortion around the metal items, even retrospectively, to improve the visualisation of medical images for clinical interpretation with no increase in patient dose.
“It is an unfortunate fact of life that in a busy city A&E we see all sorts of trauma cases. Being able to examine a patient precisely, with potential metal fragments inside them, is a great advantage in treatment planning,” explained CT modality lead radiographer Karen Macdonald. “Without the SEMAR CT technology the metal would cause distortion on the resulting images and could obscure tissue or bone imagery. Now, we can confidently see if fragments are inside the body and rapidly understand what impact they have caused.”
