目的： 探讨腰椎退行性滑脱与MRI棘间韧带T2WI高信号之间的关系，以提高对棘间韧带信号改变的认识。
方法： 收集2018年3月至2020年3月临床诊断为腰椎退行性滑脱43例患者的MRI资料，男19例，女24例，年龄50~92岁，平均69岁。利用影像归档和通信系统（picture archiving and communication systems，PACS）调阅影像，记录滑脱节段与非滑脱节段棘间韧带出现T2WI高信号的分布情况和发生率，利用Spearman分析棘间韧带的T2WI高信号与腰椎滑脱程度的关系。
结果： 除8条韧带因图像显示不佳未计入统计结果外，43例患者共207个腰椎椎体和相应的棘间韧带入组研究。根据Meyerding分型法，43例患者共有48个节段出现滑脱，Ⅰ度滑脱41个节段，Ⅱ度滑脱7个节段。滑脱节段对应的棘间韧带出现T2WI高信号30例，其中L2，3节段3例，L3，4节段3例，L4，5节段20例，L5S1节段4例；159个非滑脱节段对应的棘间韧带出现T2WI高信号53例，其中L1，2节段6例，L2，3节段6例，L3，4节段13例，L4，5节段7例，L5S1节段21例。滑脱节段与非滑脱节段相比，棘间韧带T2WI高信号的发生率分别为62.5%和33.3%，差异有统计学意义（χ2=13.06，P<0.05）。Spearman相关分析显示棘间韧带T2WI高信号的出现与腰椎滑脱程度呈正相关（r=0.264，P<0.05）。
结论： 退行性腰椎滑脱患者中滑脱椎体的棘间韧带出现T2WI高信号更多见，T2WI高信号的出现与椎体滑脱的程度呈正相关，在影像诊断中应引起足够重视。 |

Abstract:
Objective: To explore the relationship between lumbar degenerative spondylolisthesis and T2WI high signal in the interspinous ligament in MRI in order to improve the understanding of the signal changes of the interspinous ligament.
Methods: The clinical data of 43 patients with clinically diagnosed lumbar degenerative spondylolisthesis were collected from March 2018 to March 2020,there were 19 males and 24 females,aged 50 to 92 years with an average of 69 years old. Using picture archiving and communication systems (PACS) to access images and record the distribution and incidence of T2WI high signal in the interspinous ligament between the slipped and non-slipped segments. Using Spearman correlation analysis to explore the relationship between the T2WI high signal of the interspinous ligament and the degree of lumbar spondylolisthesis.
Results: Except for 8 ligaments that were not included in the statistical results due to poor image quality,43 patients with a total of 207 lumbar vertebrae and interspinous ligaments were included in the study. According to the Meyerding classification method,43 patients had a total of 48 segments with spondylolisthesis,41 segments in grade Ⅰ and 7 segments in grade Ⅱ. There were 30 cases of MRI T2WI high signal in the interspinous ligament corresponding to spondylolisthesis segment,including 3 cases on L2,3 segment,3 cases on L3,4 segment,20 cases on L4,5 segment,and 4 cases on L5S1 segment. And there were 53 cases of MRI T2WI hyperintensity in 159 non-slipped interspinous ligaments,of which 6 cases were at L1,2,6 were at L2,3,13 were on L3,4,7 were on L4,5,and 21 were on L5S1. Compared with the non-slipped segment,the incidence of high signal on the T2WI of the interspinous ligament was 62.5% and 33.3%,respectively,and the difference was statistically significant (χ2=13.06,P<0.05). Spearman correlation analysis showed that the presence of T2WI hyperintensity of interspinous ligament was positively correlated with the degree of lumbar spondylolisthesis(r=0.264,P<0.05).
Conclusion: In patients with degenerative lumbar spondylolisthesis,the MRI T2WI hyperintensity is more common in the interspinous ligament. The occurrence of T2WI high signal is positively correlated with the degree of spondylolisthesis,which should be payed enough attention in imaging diagnosis. |
