Publikováno v: Nihon Hoshasen Gijutsu Gakkai zasshi. 72(6)

BACKGROUND A clear coronary CT angiography (CCTA) can be obtained when temporal resolution (TR) is shorter than slow filling (SF) duration. The SF duration was calculated by the following equation: SF=-443+0.742 (RR-PQ). Although, the TR of half and
