The Value of MR 3D CISS Sequence in Diagnosis of Trigeminal Neuralgia Caused by Vascular Compression

Objective To explore the value of MRI three-dimensional CISS sequence in diagnosis of trigeminal neuralgia caused by vascular compression.Materials and Methods Thirty one patients with trigeminal neuralgia were analyzed retrospectively.The 3D-CISS MR images were compared with the surgical results.Results Preoperative MR 3D-CISS images showed 29 cases(29/31) of trigeminal nerve compression with the positive rate of 93.5%.3D-CISS images had high coincidence with surgical findings.Conclusion 3D-CISS images can clearly show the trigeminal nerve and the vessel compression,which is important for diagnosis and treatment.MR 3D-CISS sequence is an ideal preoperative examination for trigeminal neuralgia caused by vascular compression.
