The value of application of MRI special sequence in diagnosis of trigeminal neuralgia and facial spasm

摘要

AIM:To evaluate the diagnosis value of MRI for neurovascular compression(NVC)in trigeminal neuralgia(TN)and facial spasm(FS).METHODS:15patients with TN and 2patient with FS underwent SE T1WI and T2WI first,then 3D-TOF-SPGR sequences.RESULTS:NVC was found in all the pa-tients,MRI findings were consisten t with the surgical operative findin gs completely.CONCLUSION:It is considered to be of important to use MRI to find out the causes of TN and FS,esp ecially to utilize the 3D-TOF-SPGR sequences,which may possess high se nsitivity in determining NVC.
