目的报道核磁共振多平面和曲面重建技术在鞍区占位病变对鞍区重要结构的显示效果和探讨其在显微外科手术入路选择的作用。方法通过应用核磁共振和核磁共振多平面重建技术对鞍区常见肿瘤进行术前检查,重建鞍区病变和周围重要结构整体解剖三维切面,显示视神经、视交叉、垂体柄和视丘部等的三维结构,指导手术计划。结果13例鞍区肿瘤通过核磁共振多平面重建技术能清楚显示受肿瘤压迫移位的视神经、视交叉、动眼神经、视丘部和垂体柄等结构。其中垂体瘤8例、颅咽管瘤3例、鞍结节脑膜瘤2例均获全切除。结论核磁共振多平面重建技术在显示鞍区整体结构的效果良好,术前应用核磁共振多平面重建技术检查鞍区病变有助于其显微外科手术入路的选择。
Objective To report the effect of magnetic resonance multiplanar and curved surface reconstruction on the important structure of saddle area in the saddle area and to explore its role in microsurgery approach. Methods Preoperative examination of common tumors in the sellar area was performed by using MRI and MR planar reconstruction techniques to reconstruct the anatomical three-dimensional anatomy of the lesion in the saddle area and the surrounding important structures. The 3D images of the optic nerve, the optic chiasm, the pituitary stalk and the hypothalamus were displayed. Structure, guide the surgical plan. Results Thirteen cases of sellar tumors were able to clearly show the structure of optic nerve, optic chiasm, oculomotor nerve, optic chiasm and pituitary stalk by oppression of tumor by nuclear magnetic resonance multiplanar reconstruction. Among them, 8 cases of pituitary tumor, 3 cases of craniopharyngioma, 2 cases of saddle nodular meningioma were removed. Conclusions MR planar multiplanar reconstruction is effective in displaying the overall structure of the saddle region. Preoperative application of MRI multiplanar reconstruction to detect the lesion in the saddle region is helpful for the selection of microsurgical approaches.
