A 2D zero TE imaging technique was implemented with a gradient-extended 2D spiral-in excitation to excite a slice within 3mm full-width-half-maximum (FWHM) with pulse duration less than 6ms and spiral-out acquisition (GRESS-ZTE) strategy. Our preliminary data showed its ability to acquire signals in bones with very short T2*.
