Abstract：Objective To investigate the diagnostic value of 3D VIBE enhanced scanning in MRTA negative trigeminal neural -gia.Me thods MRTA negative patients with trigeminal neuralgia were examined 3D VIBE enhanced scanning, 12 cases were line axial, coronal and oblique sagittal MPR in the Siemens workstation, the offending vessels were MIP.The relationship of the offen-ding vessels and the trigeminal nerve were observed.All patients were confirmed by MVD surgery.Results 1) 3D VIBE en-hanced scanning showed offending vessels in 12 cases, the display rate was 100%(12/12), including 7 cases of oppression Ⅰdegree, 2 degreeⅡ, 3 cases Ⅲdegree, 7 cases of vascular surgery in contact with the nerve, 2 cases of adhesions, 3 cases of oppression;2) 10 cases of vein were oppressed, accounting for 83.3%(10/12), including 7 cases of oppression Ⅰ degree, 2 degree Ⅱ, 1 case of gradeⅢ, two cases were oppressed by small artery and vein, accounting for 16.7%(2/12) , which wereⅢdegree of oppression;3) MIP, MPR can display stereoscopic offending vessels and three-dimensional relationship with the trigem-inal nerve.Conclusion 3D VIBE enhanced scanning is an effective complement to MRTA negative trigeminal neuralgia, which can provide a comprehensive anatomical information for MVD surgery.
