The value of MRI 3D-CISS sequence in trigeminal neuralgia-related diseases

Objective To explore 3D constructive interference insteady state sequence value of related diseases in trigeminal neuralgia. Methods A retrospective analysis of 62 cases of trigeminal neuralgia as the main symptoms of patients with brain magnetic resonance imaging (MRI) routine scan and 3D constructive interference insteady state (3D-CISS) sequence images, of which 12 cases were enhanced scan, comparative analysis of MRI 3D-CISS sequence and conventional sequence of trigeminal nerve. The lesion showed the condition and was compared with the outcome of the operation. Trigeminal neuralgia-related lesions mainly included the trigeminal nerve brain pool around the vascular compression or transition, solid tumors and tumor-like lesions. Results Preoperative MRI 3D-CISS sequence was used to diagnose the vascular compression or metastasis of the trigeminal nerve pool segment in 46 cases. Forty-five patients were found to be responsible blood vessels. The 3D-CISS sequence showed 95.83% coincidence with surgical exploration. The routine sequence could not show the trigeminal The brain around the brain was forced or pushed. 3D-CISS sequence showed eight cases of solid tumors, routine scan showed six cases of solid tumors. Tumor-like lesions were shown in 6 cases of MRI3D-CISS sequences and routine plain scan sequences. The sensitivity of 3D-CISS sequence to trigeminal neuralgia-related disease was 96.77%, and the sensitivity of MRI routine scan to trigeminal neuralgia was only 19.35%. There was significant difference in the sensitivity of 3D-CISS sequence and conventional plain scan sequence to trigeminal neuralgia-related diseases (P<0.01). Conclusions MRI 3D-CISS sequence has a significant advantage in trigeminal neuralgia-related disease, and patients with trigeminal neuralgia should routinely use 3D-CISS sequences.
