Abstract：Objective To explore whether segmentation and 3D modeling are more accurate in the preoperative detection of the
neurovascular relationship (NVR) in patients with trigeminal neuralgia (TN) compared to MRI fast imaging employing steady-state
acquisition (FIESTA). Methods Segmentation and 3D modeling using 3D Slicer were conducted for 40 patients undergoing MRI
FIESTA and microsurgical vascular decompression (MVD). Results The NVR, as well as the offending vessel determined by MRI
FIESTA and 3D Slicer, was reviewed and compared with intraoperative manifestations using SPSS. The k agreement between the
MRI FIESTA and operation in determining the NVR was 0.232 and that between the 3D modeling and operation was 0.6333. There
was no significant difference between these two procedures (c2 = 8.09, P=0.088). The k agreement between the MRI FIESTA and
operation in determining the offending vessel was 0.373, and that between the 3D modeling and operation was 0.922. There were
significant differences between two of them (c2=82.01, P=0.000). The sensitivity and specificity for MRI FIESTA in determining the
NVR were 87.2% and 100%, respectively, and for 3D modeling were both 100%. Conclusion The segmentation and 3D modeling
were more accurate than MRI FIESTA in preoperative verification of the NVR and offending vessel. This was in consistent with
surgical manifestations and was more helpful for preoperative decision and surgical plan.
