RESUMEN
Objective To investigate the value of the three-dimensional high-resolution magnetic resonance imaging curve planar reformation(CPR)combined with virtual endoscopy reconstruction in vascular compression of trigeminal neuralgia.Methods 65 pa-tients with trigeminal neuralgia performed three-dimensional MR doubly excited balanced steady-state free precession sequence (3D-FIESTA-C),and CPR combined with virtual endoscopy reconstruction was used to evaluate the relationship of neurovascular anato-my.And 60 cases with microvascular decompression (MVD)surgery were analyzed.Results 65 cases of 3D-FIESTA-C CPR com-bined with MRVE showed responsibility vascular with a positive rate of 92.3% (60/65).60 cases of all patients with the results of surgery showed responsibility blood vessels and oppression parts with 3D-FIESTA-C CPR combined with MRVE,and it was found that the findings of oppression had a good consistency with MVD with the diagnose accordance rate of 95% (57/60).Conclusion Three-dimensional high-resolution magnetic resonance imaging CPR combined with virtual endoscopy reconstruction can be a new method to clearly and accurately show the anatomical relationship between blood vessels and nerves,which helps to improve the posi-tive rate of detection and to give operative guidance.
