Abstract
MR imaging was performed using a superconducting 1.5 Tesla Siemen's Magnetom SP whole body imaging system with a standard planar elliptical spine coil used as an rf receiver. The imaging sequence consisted of a gradient-echo sequence with incremented flip angle series and k-space segmentation such that 6 or 8 phase-encoding steps were acquired in rapid sequence, constituting one segment. Sixteen or 20 interleaved segments were acquired so as to complete the 120, 128, or 160 X 256 matrix. A fat saturation pulse was applied prior to each segment so as to null signal from epicardial fat and thus enhance signal from coronary flow. A repetition time (TR) of 13 msec and an echo time (TE) of 8 msec were used with a slice thickness of 4 or 5 mm and 230 mm field-of-view (in-plane resolution of 1.4 - 1.9 mm X 0.9 mm). All imaging was performed within a single breath-hold.
