Abstract

The debate still raged between the manufacturer of the dual source CT scanners versus the rest of the world as to the actual usefulness and the clinical application of the dual source CT scanners.  The rest of the world argued that dual source has a higher lifetime cost as it uses 2 tubes whereas the proponents of the dual source CTs pointed to their better temporal resolution, dual energy features etc.  Jiang et al in their meta-analysis look at dual source 64 detector row CT data versus single source 64 detector row CT data for the detection of coronary artery disease.  In the 51 papers that they analysed the dual source came out ahead in terms of its specificity allowing better intervention decisions as compared to the single source.
