Dual-phase DECT myocardial perfusion cuts time, dose
By Eric Barnes
There's no need to acquire images during both stress and rest phases in dual-energy CT (DECT) myocardial perfusion imaging, say researchers from the U.S. and Germany. A stress phase combined with a delayed-enhancement phase performs just as well while reducing radiation dose by a third.
