The aim of this review was to identify publications relating to the use of spiral and electron beam computed tomography (CT), in order to draw conclusions about the effectiveness of latest generation CT devices. The Fineberg evaluative framework was used, with publications sought for all clinical applications at the levels of health economics, patient outcome and therapeutic impact. For diagnostic impact and diagnostic performance, specific clinical uses were selected: the investigation of liver lesions using spiral CT (SCT); the investigation of pulmonary embolism (PE) using SCT; and the diagnosis and prediction of coronary artery disease (CAD) using electron beam CT (EBCT).
Authors' recommendations: MEDLINE and BIDS-ISI are comprehensive sources of references in this subject area. 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. SCT detects liver lesions that are not seen with conventional CT. EBCT has a low specificity when applied to the diagnosis of symptomatic CAD. While the evidence suggests EBCT use for population studies, it does not support its use to track CAD progression in individuals. The introduction of SCT will not cause a significant increase in radiation dose compared with similar examinations performed with conventional CT.
