摘　　要：目的探讨MRI对椎间盘脱出并肉芽组织增生的诊断及临床应用价值。方法将T2WI示脱出髓核周围和其内高信号影27例患者行MRI增强扫描,分析其表现及特点。结果 27例共30个腰椎间盘脱出,脱出髓核与硬脊膜分界模糊9个,部分分界清楚21个,增强扫描髓核周围线样强化6个,带状强化24个,17个与患侧神经根粘连。6个脱出髓核内信号稍减低,8个信号稍增高,5个明显增高,11个呈等信号,增强扫描髓核无强化26个,斑片状强化4个。结论 MRI能准确诊断腰椎间盘脱出及肉芽组织增生。Objective To discuss the MRI in the diagnosis of prolapsed of lumbar intervertebral disc associated with proliferation of granulation tissue and it＇s clinical value. Methods Using T2W1 to display the hyperintensity shadow in the peripheral and within prolapsed nucleus pulposus, 27 cases underwent MRI enhanced scan and it＇s manifestation and feature were analyzed. Results In the 27 cases, the prolapses of lumbar intervertebral disc were found in 30. Among them, the boundary between the relapse nucleus pulposus and dura mater spinalis was vague in 9 and partial clear borders in 21. Enhanced scan showed linear-like enhancement around nucleus pulposus in 6, zonular enhancement in 24, with affected lateral adhesion of nerve root in 17. Slightly hypointensity within prolapsed nucleus pulposus was in 6, slightly hyperintensity in 8, obviously hyperintensity in 5 and isointensity in ll.Enhanced scan indicated without enhancement of nucleus pulposus in 26 and patchy enhancement in 4. Conclusion MRI could accurately diagnose the prolapse of lumbar intervertebral disc associated with proliferation of granulation tissue.
