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.

ABSTRACT
Objective@#To explore the clinical significance of multi slice spiral CT in the diagnosis of small intestinal diseases.@*Methods@#78 patients suspected with small intestinal diseases were selected and scanned by multi detector row spiral CT instrument.The lesion position, size, type, range and distant metastasis were observed.Then, the clinical and pathological results were compared and analyzed.@*Results@#The final clinicopathological diagnosis had 49 positive cases, 29 negative cases among the 78 patients.The MDCTE had 40 positive cases, which had correspondence with pathological diagnosis; 29 negative cases had correspondence with pathological diagnosis; 9 cases had been misdiagnosed.The sensitivity of MDCTE in diagnosis of small intestinal diseases was 81.63%(40/49), the specificity was 100.00%(29/29), the positive predictive rate was 100.00%(40/40), the negative predictive rate was 76.32%(29/38), the accuracy of diagnosis was 88.46%[(40+ 29)/78].@*Conclusion@#MDCTE has important clinical significance in the diagnosis of small intestinal diseases.
