【摘要】 目的:评价CT对下段腰椎椎间孔狭窄的诊断及其临床意义。方法:回顾分析72例腰椎椎间孔狭窄的CT表现。男性57例,女性15例。年龄36-64岁,平均53.5岁。结果:腰椎椎间孔狭窄的主要表现为:①腰椎间盘变性,纤维环及软骨板形成的软组织块突出或膨出导致椎间孔狭窄;②椎小关节突增生肥大及骨赘形成,突入侧方椎间孔致使侧隐窝区及中间区狭窄;③腰椎体后外缘骨质增生肥大、骨刺及骨赘形成,突入侧方椎间孔引起狭窄;④椎小关节突骨赘形成、黄韧带肥厚伴侧外方椎间盘膨出导致全段椎间孔狭窄。结论:CT检查可充分显示椎间孔狭窄的解剖结构及引起椎间孔狭窄的各种病理改变,从而可为临床提供可靠的影像学诊断依据。更多还原

【Abstract】 Objective:To evaluate CT diagnosis of the lumbar foramenal stenosis and itsclinical significance in the lower lumbar spine.Methods:CT finding in 72 cases with lumbar foramenal stenosis were retrospectively analysed. 57 males and 15 females, aged 36 - 64 years with a mean of 53. 5. Results: The main abnomalties demonstrated by CT included:①Degeneration of the vertebrae disk, leading to extraforaminal stenosis;②Hypertrophy of the articular process, osteophyte formation involved stenosis in lateral recess and middle region lumbar intervertral foramen;③Sclerosis and esteophyte formation on boder of the vertebral body involved intervertebral foramen, leading to stenosis;④Osteophyte formation of the articular process and discul bulgin or hemation of the inferior intervertelral disc and thickned of the ligament flava invalved all segement of the vertebral foramen. Conclusion: CT can demonstrated anatomic structure of the lumber intervertebral foramen and pathologic change of the lumbar foramen stenosis and provide reliable images for diagnosis of the lumbar foramen stenosis.更多还原
