Abstract：Objective To discuss the application value of TSE (Turbo Spin Echo) fat saturation (FS) and FLASH (Fast Low Angle Shot) FS sequences in cervical enhanced scanning. Methods Altogether 30 patients underwent cervical contrast-enhanced MRI (CE-MRI) scanning with Siemens Avanto 1.5 T MRI scanner. The images of all 30 cases were obtained on both the TSE-FS and FLASH-FS sequences, and then were evaluated and scored by two experienced radiologists separately. Scoring results were analyzed statistically with the Wilcoxon test. Results T1WIs with both of TSE-FS and FLASH-FS sequences in all orientations including transverse and coronal and sagittal dimensions, had been acquired in all 30 patients. T1-FLASH-FS sequences were 2'55" faster than T1-TSE-FS in the total acquisition time in all dimensions. As for motion artifacts, in all transverse and coronal as well as saggital orientations, it was statistically significant (P<0.05) between T1-FLASH-FS and T1-TSE-FS sequences with artifacts in the former one less than the later one. As for vascular pulsatility artifacts, only in transverse scanning, it was statistically significant (P<0.05) between T1-FLASH-FS and T1-TSE-FS sequences with artifacts in the former one less than the later one; but in the other two orientations including both coronary and saggital orientations, on the contrary, it was not statistically significant (P>0.05). As for fat saturation effect, in all the transverse and coronal as well as sagittal orientations, it was better on T1-FLASH-FS sequence than the T1-TSE-FS with statistical significant differences between the two scores (P<0.05). Conclusion With shorter acquisition time, less motion artifacts and pulsatility artifacts as well as better fat suppression effect, T1-FLASH-FS sequence could better meet the diagnostic requirements in comparison with T1-TSE-FS sequence in cervical CE-MRI scanning.
