Abstract：Objective To explore the values of 3-dimensional constructive inference in steady state (3D-CISS) combined with 3-dimensional time of flight (3D-TOF) sequences MRI to the diagnosis of the vessels responsible for primary trigeminal neuralgia (PTN). Methods The clinical data of 79 patients with PTN, who underwent the first microvascular decompression (MVD) in Department of Neurosurgery, Xuanwu Hospital, Capital Medical University from January, 2016 to December, 2016, were analyzed retrospectively. By comparing the offending vessels preoperatively identified by 3D-CISS combined with 3D-TOF sequences MRI with the offending vessels intraoperatively detected by the operators, the accuracy of 3D-CISS combined with 3D-TOF sequences MRI in diagnosis of offending vessels was evaluated. Results The preoperative 3D-CISS combined with 3D-TOF sequences MRI found that there were offending vessels in 75 patients and there were no offending vessels in 4 patients. The operators intraoperatively found that there was at least 1 offending artery in each of 73 patients with PTN and there were no offending vessels in 4 patients. The sensitivity and specificity of 3D-CISS combined with 3D-TOF sequences MRI for detecting the offending vessels were 98.6％ and 50.0％ respectively and its accuracy for diagnosing the offending vessel was 94.9％ before the operation. Conclusion The pre-operative 3D-CISS combined with 3D-TOF sequences MRI can provide the important information of the offending vessels for MVD surgery in the patients with PTN.
