Abstract：Objective To investigate the effectiveness of application of 3D-FIESTA (Three Dimensional Fast Imaging Employing Steady-State Acquisition) and 3D-TOF-MRA (3D Time-of-Flight Magnetic Resonance Angiography) in preoperative assessment of hemi-facial spasm. Methods Sixty-nine patients with hemi-facial spasm who have been treated in the hospital from January 2014 to April 2015 were included in our study. 3D-FIESTA and 3D-TOF-MRA were performed for all the patients prior to micro-vascular decompression. Having taken surgical findings as the gold standard, the offending vessels determined by 3D-TOF-MRA and 3D-FIESTA were compared clinical outcomes. Results Neuro-vascular contact/compression (NVC) was found more frequently in the symptomatic sides (61/69, 88.4%) than that in the non-symptomatic sides (3/69, 4.3%). The sensitivity and accuracy of 3D-TOF-MRA and 3D-FIESTA MRI for identifying offending vessels comparing with surgical findings was 88.4% (61/69) and 100%(61/61), respectively. Comparing with 3D-TOF-MRA or 3D-FIESTA images, the offending vessels were more detected by comprehensive analysis of 3D-TOF-MRA and 3D-FIESTA (P= 0.021 and 0.063, respectively). Conclusion Preoperative 3D-TOF-MRA and 3D-FIESTA could show the neuro-vascular relationship and help identify the offending vessels for the patients with hemi-facial spasm.
