磁共振PROSET技术在诊断脊神经根病变中的价值

目的　探讨磁共振PROSET技术在显示和诊断脊神经根病变中的价值。方法　收集可疑腰骶部脊神经根病变 10例 ,正常志愿者 5例 ,观察PROSET的原始图像和MIP重建图像对脊神经根的显示情况。结果　PROSET的原始图像更有利于神经根的显示。 10例可疑患者中发现有 4例神经根鞘膜囊肿 ;2例脊神经根损伤 ;1例神经纤维瘤 ;其余 3例和 5例志愿者的腰骶脊神经根正常结构显示良好 ,能清晰地显示硬膜囊、马尾神经、神经根、脊神经节及节后一段脊神经纤维。结论　PROSET对脊神经根的显示完整清晰 ,对脊神经根的病变诊断和鉴别诊断具有较高价值。

Application of MR PROSET Technique in Diagnosing Nerve-roots Diseases

Objective To discuss the value of MR PROSET technique in showing and diagnosing spinal nerve-roots diseases.Methods 10 cases were suspected of spinal PROSET scanning technique and MIP reconstruction .Results Primary images of PROSET were superior to display nerve-roots.10 suspected cases included 4 cases of spinal nerve- root cyst;2 cases of nerve-root injury;one case of neurofibromatosis .Three of them were normal.Conclusion PROSET technique can display nerve-roots clearly and help diagnose the nerve-roots diseases.
