SCT detection performance for PE is better for the central vessels alone than for both central and peripheral vessels together. The most likely role for EBCT is in excluding obstructive CAD in the older population. Interobserver and intraobserver reproducibility of EBCT for CAD is acceptable, but interexamination reproducibility is not. A total of 11 studies of radiation dose were included in the review. Of four studies comparing SCT dose with that of conventional CT, the general agreement was of an insignificant increase in dose over conventional CT, with SCT offering the potential for reducing the dose by increasing pitch.
Conclusions is a bullet.
There is no strong evidence about any aspect of the use of latest generation CT at the health economics, patient outcome or therapeutic impact levels. While the evidence suggests EBCT use for population studies, it does not support its use to track CAD progression in individuals. Recommendations for research is a bullet. Research is undertaken in those areas where the evidence will lead to the greatest benefits to patients, either through improved patient outcomes or the most efficient use of NHS resources. The Standing Group on Health Technology advises on national priorities for health technology assessment.
