Zusammenfassung
Purpose: A novel device for 3T whole body imaging was recently made available. The aim of the resent study was to describe our first experiences with this system for T2-weighted 3D whole spine imaging. Methods: MR Imaging of the whole spine was performed by implementing a 3D fast spin echo sequence with variable flip angle refocusing pulses at 3T, and 1.5T. Signal-to-noise ratio(SNR) was compared on both systems. Results: Mean values for SNR were significantly higher at 3T (346±214) for 1.0mm voxel size compared to 1.5T (202±41), but showed considerably higher variability at 3T. At 3T measurements with 0.9mm vox…
