Abstract:
Objective To explore the value of three-dimensional constructive inference in steady state sequence (3D-CISS se-quence)in case of midbrain aqueduct obstruction.Methods 46 cases with midbrain aqueduct obstruction were scanned with FLASH T1 WI、TSE T2 WI and 3D-CISS sequence at 3.0T superconductive MR scanner.The original images of the 3D-CISS sequence were reconstructed.The images of three sequences showing midbrain aqueduct obstruction were observed and analyzed.Results The de-tection rate of the midbrain aqueduct obstruction was 13% 、71.7% and 100% in FLASH T1 WI、TSE T2 WI and 3D-CISS sequence, respectively.The difference between the three sequences were significant (P <0.01 67).Conclusion 3D-CISS sequence shows mid-brain aqueduct obstruction more accurately.
