Fig. 2From: Computed tomography for myocardial characterization in ischemic heart disease: a state-of-the-art reviewDual-source CT uses a shuttle mode, alternating table position using two acquisitions merged into one image, to get a z-axis of 7.3 or 10.2 cm for the second- and third-generation systems. Multi-detector CT systems use wide detector with 280 or 320 rows to reach a z-axis range of 8 or 16 cm, respectively. Both approaches allow for whole-heart imagingBack to article page
