【摘要】：目的结合磁共振成像常规序列成像,应用T2弛豫时间图(T2 relaxation time mapping)成像测量脊柱结核病变,分析脊柱结核的特征表现、T2值范围及其诊断价值。方法对病例组25名脊柱结核患者60个病变椎体、自身对照组60个病变临近正常椎体及对照组25名健康志愿者60个正常椎体行脊柱矢状面自旋回波(fast spin echo,FSE)序列8回波扫描,自动生成T2图,并划定感兴趣区(region of interest,ROI)测量T2值。病例组分别与自身对照组和对照组之间采用配对t检验和两独立样本t检验,以P0.01为差异有统计学意义。结果病变椎体及椎旁冷脓肿在T2图上均显示为红绿蓝的混杂色阶,且病变椎体、病变临近正常椎体、对照组正常椎体的T2值分别为(110.32±13.84)ms、(70.06±9.03)ms、(77.29±4.19)ms,病例组分别与自身对照组和对照组之间有统计学差异(P0.01)。结论 T2弛豫时间图技术可以量化评估脊柱结核病变内组织成分的变化,对脊柱结核的诊断及鉴别诊断有一定的指导意义。
[Abstract]:Objective to measure spinal tuberculosis with T2 relaxation time map and T2 relaxation time mapping combined with conventional Mr imaging, and to analyze the characteristic features of spinal tuberculosis and its diagnostic value.Methods Sagittal echo fast spin echo sequence was performed in 60 vertebral bodies of 25 patients with spinal tuberculosis, 60 adjacent normal vertebrae in self control group and 60 normal vertebrae in control group.Automatically generate T2 map and delineate region of interest ROI to measure T 2 value.Pairing t test and two independent sample t test were used between case group and self control group and control group respectively. The difference was statistically significant with P0.01.Results the lesion vertebrae and paravertebral cold abscess showed red, green and blue hybrid color on T2, and the lesion was close to normal vertebral body.The T _ 2 values of normal vertebrae in the control group were 70.06 卤9.03g / s and 77.29 卤4.19m / s, respectively. There was a significant difference between the case group and the control group (P < 0.01).Conclusion T2 relaxation time chart technique can be used to quantitatively evaluate the changes of tissue components in spinal tuberculosis, which is helpful for the diagnosis and differential diagnosis of spinal tuberculosis.
