In clinical routine, TSE is used as the standard T2-weighted imaging sequence. The scan time usually takes several minutes for multislice imaging along either one of the three anatomical orientations (transverse, coronal, and sagittal). Obtaining all these information using TSE is not practical considering the clinical throughput. To achieve this goal, we propose to use the TIDE bSSFP, a sequence shown to carry T2 weighting and intrinsic fat suppression. Its scan time takes only one second for a single slice scan. To evaluate the feasibility, we compared the image quality of TIDE bSSFP with those of FS-T2-TSE and FS-T2-TGSE (GRASE) quantitatively, by means of ROI analysis of the gray and white matters of the brain.
