| Abstract: | Objective：To explore the value of T2 relaxation time,magnetic resonance spectroscopy（MRS） and apparent diffusion coefficient（ADC） in the lumbar intervertebral disc degeneration.Materials and Methods：Comparison of ADC values,MRSRATIO and T2 relaxation times in 177 discs was performed at different anatomic levels and different Pfirrmann grades in 40 patients.Results：The T2 relaxation times and ADC values were significantly correlated with Pfirrmann grades in different discs,but not in different anatomic levels.ADC values and T2 relaxation time were not correlated with different anatomic levels.Conclusion：ADC values and T2 relaxation time of the lumber intervertebral discs were correlated with increasing Pfirrmann grade.The results of this study support the feasibility of quantitatively assessing spinal degeneration.The values of the MRSRATIO in lumbar intervertebral disc degeneration will be further studied. |
