New generation cardiac CT scanners (Aquilion ONE, Brilliance iCT, Discovery CT750 HD and Somatom Definition Flash) for cardiac imaging in people with suspected or known coronary artery disease in whom imaging is difficult with earlier generation CT scanners

7 Recommendations for further research

The diagnostics advisory committee has not made specific recommendations for further research. Nevertheless, the committee recognised that there is uncertainty about a number of issues relating to the new generation cardiac CT scanners for the assessed population (for example, test accuracy in people with obesity and people with very high calcium scores) and that there is concern that angiography was not an accurate gold standard.
