Abstract:
Objective To explore the application effect of multimodal MRI in the diagnosis of lumbar intervertebral disc degeneration.Methods A total of 78 patients with lumbar intervertebral disc degeneration treated conservatively were retrospectively selected.The patients underwent sagittal T2WI,axial T2WI sequence and sagittal synthetic MRI scanning and post-processing to generate T1,T2 and proton density(PD)mapping quantitative sequences by GE Signa Pioneer 3.0T MR machine.The T1,T2 and PD values of the anterior and posterior annulus fibrosus and nucleus pulposus of L1-L2 to L5-S1 lumbar intervertebral disc were measured.The Pfirrmann grade,visual analogue scale(VAS)and Oswestry disability index(ODI)scale of each intervertebral disc were evaluated.The T1,T2,PD,VAS and ODI of patients with different Pfirrmann grades were compared.Pearson linear analysis was used to analyze the relationship between T1,T2,PD and VAS,ODI.Spearman rank correlation method was used to analyze the relationship between T1,T2,PD and Pfirrmann.Logistic regression analysis was used to analyze the evaluation value of T1,T2 and PD in Pfirrmann.Results With the increase of Pfirrmann grade,the T1,T2 and PD values of patients decreased,while the VAS score and ODI increased(P<0.05).The T1,T2 and PD values were negatively correlated with VAS score,ODI and Pfirrmann grade(P<0.05).Logistic regression analysis showed that T1,T2 and PD values had good evaluation values for Pfirrmann grade(P<0.05).Conclusion Multimodal MRI can effectively evaluate the Pfirrmann grade,pain and lumbar function of lumbar intervertebral disc degeneration,which can be used to help determine the diagnosis.
