目的 探讨螺旋CT多层面重建 (MPR)对腰椎间盘病变的诊断价值。方法 经常规扫描和螺旋扫描MPR重建腰椎间盘病变患者共 41例 ,对L3～ 4 、L4～ 5和L5～S1扫描所得结果进行对比观察。结果 41例经常规扫描患者中有 35例表现为椎间盘膨出或/和突出 ,经螺旋CT扫描MPR重建示有 36例表现为神经根受压、硬膜囊受压或椎间孔骨性狭窄 ,其中常规扫描无异常发现的 6例患者 ,经MPR示椎间盘压迫神经根或椎间孔骨性狭窄致神经根受压。结论 MPR重建在诊断腰椎间盘病变、显示腰椎疾病的原因以及腰椎疾病的鉴别诊断等方面具有重要价值
Objective To investigate the value of multi-slice spiral computed tomography (MPR) in the diagnosis of lumbar disc disease. Methods A total of 41 patients with lumbar disc disease were retrospectively analyzed by routine scanning and spiral CT scan. The results of L3 ~ 4, L4 ~ 5 and L5 ~ S1 scanning were compared. Results Thirty-five patients in routine scanning showed intervertebral disc bulge and / or protrusion. Thirty-six patients underwent spiral CT scan with MPR reconstruction showed nerve root compression, dural sac compression or intervertebral foramen osseous stenosis , Of which 6 cases of normal scan without abnormal findings, by MPR showed disc compression nerve root or foraminal obstruction caused by nerve root compression. Conclusions MPR reconstruction is of great value in the diagnosis of lumbar disc disease, the reason of lumbar disc disease and the differential diagnosis of lumbar disc disease
