直立位椎管造影对腰椎间盘突出的诊断价值

The value of upright standing myelography in the diagnosis of lumbar disc herniation

目的 评价直立位椎管造影对腰椎间盘突出的诊断价值。方法 经CT或MRI诊断的腰椎间盘突出 196例术前进行直立位椎管造影检查。结果 直立位椎管造影的诊断结果与CT或MRI基本符合 ,但有 7例直立位椎管造影发现L4～ 5椎间盘突出并伴有神经根受压 ,而CT或MRI未能显示。结论 直立位椎管造影对腰椎间盘突出的诊断可能优于CT或MRI ,尤其对L4 5椎间盘突出伴有神经根受压的病例。

Objective To evaluate the value of upright standing myelography in the diagnosis of lumbar disc herniation (LDH). Methods One hundred and ninety six patients with LDH diagnosed by CT or MRI were examined by upright standing myelography before surgery. Results The most diagnosis of myelography were accorded with CT or MRI, but 7 patients of myelography with LDH at L4-5 showed compression of nerve roots, while the images of these on CT or MRI only showed disc bulge or protrusion without nerve root compression. Conclusions Myelography in the upright standing position is perhaps superior to CT or MRI for the diagnosis of LDH, especially LDH at L4-5 with nerve root compression.
