The Somatom Definition Edge is a CT scanner that can be used for computed tomography coronary angiography (CTCA), to diagnose or evaluate coronary artery disease non-invasively in people with conditions that make it difficult to obtain good-quality CTCA images. The Somatom Definition Edge has technical features that are recognised to address clinical challenges in patients who have coronary artery disease that is difficult to image, but there is no published evidence on the safety or effectiveness for this indication. It can also be used for other clinical imaging applications in adults and children. The Somatom Definition Edge typically costs about £600,000 excluding VAT, depending on the configuration.
During the review process for diagnostics guidance on new generation cardiac CT scanners, NICE became aware of the Somatom Definition Edge CT scanner, which has similar technical specifications to those recommended in the guidance. NICE has also published a medtech innovation briefing on the Aquilion PRIME CT scanner.
