Abstract:
Objective:To explore the clinical value of magnetic resonance T2-mapping imaging in the diagnosis of early intervertebral disc degeneration in obese people.
Methods:From January 2018 to June 2019, 30 obese volunteers and 30 healthy volunteers with normal weight underwent T2-mapping scan, while their routine MRI examination showed no abnormalities were slected.The T2 value of nucleus pulposus in both two groups were measured and compared.
Results:The T2 values of nucleus pulposus of intervertebral disc of lumbar 1-2, lumbar 2-3, lumbar 3-4, lumbar 4-5 and lumbar 5-sacral 1 in the control group were (108.17±10.87)ms, (113.93±11.54)ms, (126.65±10.22)ms, (118.62±8.86)ms and (111.61±10.65)ms, respectively, which of nucleus pulposus in different segments was statistically significant(F=14.28, P<0.001). The T2 values of nucleus pulposus of intervertebral disc of lumbar 1-2, lumbar 2-3, lumbar 3-4, lumbar 4-5, lumbar 5-sacral 1 in the simple obesity group were (104.90±7.67)ms, (101.10±6.61)ms, (112.65±5.75)ms, (98.27±6.18)ms, (89.82±6.34)ms, respectively, , which of nucleus pulposus in different segments was statistically significant(F=49.52, P<0.001). There were statistically significant differences in the T2 values of nucleus pulposus of intervertebral disc of lumbar 2-3, lumbar 3-4, lumbar 4-5, lumbar 5-sacral 1 between the two groups(t=5.283, 6.535, 10.327, 9.626, all P<0.001).
Conclusion:Magnetic resonance T2-mapping can detect early changes in tissue composition of intervertebral disc degeneration.Therefore, magnetic resonance T2-mapping imaging technology can provide an important reference for the early diagnosis of intervertebral disc degeneration in obese people.
