摘　　要：目的探讨腰椎间盘突出组织核磁共振成像(magnetic resonance imaging,MRI)信号强度与重吸收的相关性。方法对该院2016年2月~2020年3月因腰椎间盘突出症选择非手术治疗并获得1年以上随访的66例患者进行回顾性分析。其中重吸收27例,未重吸收39例。记录两组患者的一般资料,统计患者病程、Iwabuchi分型、MSU分型、神经根沉降征、突出组织MRI信号强度等资料,通过t检验和Logistic回归分析探讨信号强度是否是影响重吸收的独立因素。测量并计算重吸收组患者的重吸收程度(消失、明显重吸收、部分重吸收),分析其与信号强度的相关性。结果经过1年以上的随访,发生重吸收的27例患者临床症状明显改善;未发生重吸收的39例患者中,最终11例患者行手术治疗。重吸收组信号强度(32.45±12.43)%与非重吸收组信号强度(15.93±7.66)%存在差异(P<0.05)。Logistic回归分析显示,病程<1年、Iwabuchi1型或5型、MSU分型3型、神经根沉降征A型或B型、突出组织MRI信号强度相对高的患者容易发生重吸收(P<0.05)。患者的重吸收程度与信号强度存在中等正相关(r=0.572,P<0.05)。结论腰椎间盘突出组织MRI信号强度是影响重吸收发生的独立因素并与重吸收程度存在相关性,在一定程度上可以预测腰椎间盘突出后发生重吸收的概率。Objective To investigate the correlation between MRI signal intensity and resorption in lumbar disc herniation(LDH).Methods A retrospective study was conducted on 66 patients with LDH who received non-surgical treatment between February 2016 and March 2020,and followed up for more than one year.There were 27 cases in the resorption group and 39 cases in the non-resorption group.The course of disease,Iwabuchi type,MSU type,horsetail sedimentation sign Schizas classification and MRI signal intensity were recorded.T test and logistic regression analysis were used to explore whether MRI signal intensity was an independent factor affecting resorption.The degree of resorption(disappearance,obvious resorption,partial resorption)in the resorption group was measured and calculated,and the correlation between the degree of resorption and MRI signal intensity was discussed.Results After more than one year of follow-up,the clinical symptoms of 27 patients with resorption were significantly improved,and of the 39 patients without resorption,11 patients underwent surgery.There was a statistically significant difference in MRI signal intensity between the resorption group and the non-resorption group(32.45±12.43)% and(15.93±7.66)%(P<0.05).Data analysis showed that patients with course of disease less than one year,Iwabuchi type 1 or 5,MSU type 3,horsetail sedimentation sign Schizas classification type A or B,and high MRI signal intensity were prone to resorption(P<0.05).There was a significant positive correlation between the degree of resorption and MRI signal intensity(r=0.572,P<0.05).Conclusion MRI signal intensity is an independent factor that affects the occurrence of resorption of LDH and is related to the degree of resorption.It is a clinical index to evaluate the probability of resorption of LDH.
