摘要:


文题释义:

HU值:是基于椎体CT,由QCT演变而来的一种值,通过测量相应椎体感兴趣区域的信号强度,测量椎体内部骨小梁的一种方法。因为在骨质疏松椎体内部的骨小梁减少,孔隙率增加,可在CT图像中表现出一种信号,HU值则是测量这种信号,用于评估是否存在骨质疏松的情况。
2型糖尿病骨质疏松症:由于2型糖尿病患者体内脂肪的增加,影响成骨细胞和破骨细胞功能,导致骨矿化缺陷,表现为在骨小梁处的成骨细胞减少、破骨细胞增加,使骨小梁的孔隙增大的一种疾病。


背景:有研究表明基于腰椎CT的HU(hounsfield units)值可以筛查骨质疏松症,而目前因肺部感染就诊的患者增加,肺部感染合并2型糖尿病的患者也随之增加,增加了胸部CT的使用率。

目的:探讨胸部CT检查中L1椎体HU值在2型糖尿病骨质疏松症筛查中的作用。
方法:回顾性分析2020年6月至2022年6月成都医学院第一附属医院收治的244例2型糖尿病患者的临床资料。利用双能X射线骨密度仪获得骨密度T值,按WHO的骨质疏松症诊断标准,将研究对象分为非骨质疏松组(n=120)及骨质疏松组(n=124),比较两组患者一般情况、骨密度T值及胸部CT检查中L1椎体的HU值,分析HU值与各部位T值的关系并评估2型糖尿病骨质疏松症的准确性。

结果与结论:①两组患者性别、年龄、体质量指数、糖化血红蛋白、平均血糖、钙、磷、2型糖尿病患病时间、高血压病史、高脂血症病史之间对比差异无显著性意义(P > 0.05);②HU值与最低T值呈正相关(r=0.619,P < 0.01),与髋部T值呈正相关(r=0.584,P < 0.01),与股骨颈T值呈正相关(r=0.641,P < 0.01);当HU值取98时,其预测2型糖尿病骨质疏松症具有良好的准确性,敏感性为70.8%;③提示基于胸部CT检查的L1椎体HU值对2型糖尿病患者的骨质疏松症筛查具有良好的价值,可作为2型糖尿病骨质疏松症一种机会性、无成本的补充筛查方法。

Abstract: BACKGROUND: Some studies have shown that the hounsfield units (HU) value based on lumbar CT can be used to screen osteoporosis. At present, the number of patients with pulmonary infection has increased; the number of patients with pulmonary infection and type 2 diabetes is also increasing, which increases the utilization rate of chest CT. 
OBJECTIVE: To investigate the role of lumbar 1 vertebral body HU value based on chest CT in the screening of type 2 diabetes mellitus osteoporosis.
METHODS: The clinical data of 244 patients with type 2 diabetes mellitus treated in the First Affiliated Hospital of Chengdu Medical College from June 2020 to June 2022 were analyzed retrospectively. The bone mineral density was obtained by dual-energy X-ray absorptiometry. According to WHO’s diagnostic criteria for osteoporosis, the subjects were divided into the non-osteoporosis group (n=120) and the osteoporosis group (n=124). The general condition, T value and HU value of lumbar 1 vertebra in chest CT were compared, and the relationship between the HU value and T value of each position was analyzed and the accuracy of type 2 diabetes mellitus osteoporosis was evaluated. 
RESULTS AND CONCLUSION: (1) There was no significant difference in sex, age, body mass index, glycosylated hemoglobin, mean blood glucose, calcium (Ca), phosphorus (P), time of type 2 diabetes mellitus, history of hypertension and history of hyperlipidemia between the two groups (P > 0.05). (2) The HU value was positively correlated with the lowest T value of the hip (r=0.619, P < 0.01); the HU value was positively correlated with the hip T value (r=0.584, P < 0.01), and the HU value was positively correlated with the femoral neck T value (r=0.641, P < 0.01). When the HU value was 98, the prediction of type 2 diabetes mellitus osteoporosis had good accuracy, and the sensitivity was 70.8%. (3) It is concluded that the HU value of the lumbar 1 vertebra based on chest CT examination is of good value for osteoporosis screening in patients with type 2 diabetes mellitus, and may be an opportunistic and cost-free supplementary screening method for type 2 diabetes mellitus osteoporosis.
