title = "Quantitative assessment of motion effects in dual-source dual energy CT and dual-source photon-counting detector CT",
abstract = "Dual-source CT can provide high temporal resolution single energy imaging, but this is sacrificed in dual-energy mode (DS-DE). The current study evaluates a dual-source photon-counting-detector (DS-PCD) CT capable of high temporal resolution (66 ms) dual-energy imaging. A rod simulating coronary artery motion was scanned on both DS-DE and DS-PCD CT scanners and image quality was evaluated. Spatial registration - quantified by dice coefficient - between the high and low energy images was better with DS-PCD than DS-DE. Furthermore, the rod had a more circular appearance and its diameter was more accurate in iodine maps generated by DS-PCD whereas DS-DE suffered from motion artifacts.",
