Abstract
A method that incorporates cardiorespiratory-gated 2DFT spin-echo imag ing with blood flow enhancement suppression is described which enables high resolution microimaging of the rodent heart. This methodology wa s applied to obtain in vivo cardiac mouse and rat images with in-plane resolutions of 100-200 mu m using high field vertical bore magnet sys tems. Suppression of intraventricular blood flow enhancement was achie ved using a combined spin-echo/gradient-refocussed sequence to dephase magnetization from flowing spins prior to imaging.
