Synopsis

Keywords: Heart, HeartT2-mapping is generally obtained only in diastole. However, because myocardial edema can affect both diastole and systole, acquisition of T2-mapping of different cardiac phases is desirable, but it prolongs examination time and increases patient stress. To overcome this limitation, we report a new T2-mapping technique using dynamic trigger delay which enables quantitative mapping at multiple cardiac phases in one scan. In this study, we demonstrate the feasibility of this approach in healthy volunteer examination.
