[Abstract] Objective: To evaluate the application value of doubly excited Balance-SSFP sequence Curvature Plane Reconstruction (CPR) in vascular compressive Trigeminal Neuralgia (TN) and Hemifacial Spasm (HFS).Materials and Methods: Forty-eight cases with Trigeminal Neuralgia (TN) and thirty-three cases with Hemifacial Spasm (HFS) were accepted 3D-FIESTA-C scanning. The origin images were post-processed with Curvature Plane Reconstruction (CPR) on workstation. Relationship between vessels and nerves was analyzed in symptomatic side. Sixty-five out of 81 cases were compared with surgery result, and 2 magnetic resonance physicians evaluated consistency test of result through Kappa analysis.Results: Eighty-one cases through Curvature Plane Reconstruction (CPR) show that contactless of vessels and nerves were found in 8 patients, contact of vessels and nerves were found in 25 patients and oppression were found in 48 patients. In the cases of contact and oppression, 33 cases indicated that the spacing of side cistern was narrow compared with contralateral ones, and 12 cases of brain stem showed deformation. The Kappa consistency test result between CPR result and post-operation of MVD result for 65 cases done by 2 physicians was that (K values were 0.837 and 0.787 respectively), 3D-FIESTA-C combined with CPR showed source of responsible vessels, oppression position and level of nerve oppression. The sensitivity was 96.92%, specificity was 75%, PPV was 94.02% and NPV was 85.71%.Conclusion: Doubly excited Balance-SSFP sequence CPR can provide a more comprehensive and accurate viewing angle for vessels and nerves anatomy relations, and offer important evidence for pre-surgery evaluation and etiological diagnosis. |
