【摘要】：目的探讨实时弹性成像定量分析技术RTE在体质量偏瘦人群中对肾病的应用价值。方法应用RTE技术分析60例慢性肾病患者与60例体检健康者的肾脏硬度,得到12个弹性变量值,包括蓝色领域百分比(%AREA),复杂度(COMP),应变均值(MEAN),标准偏差(SD),对比度(CONT),均等性(ENT),峰度(KURT),偏度(SKEW),相关性(CORR),一致性(ASM),杂乱度(IDM),应变比B/A(肾脏皮质硬度与腰大肌硬度应变率比值B/A),分析病例组与健康组之间的12个弹性特征量的差异。结果两组间肾脏弹性图像特征量除均等性及相关性差异无统计学意义,其他弹性变量差异均有统计学意义(P0.05)。对12个弹性特征量进行Logistic回归分析,得出应变率比值B/A是诊断慢性肾病最重要的诊断参数。结论 RTE技术对偏瘦人群慢性肾病有很高的应用价值,为临床诊断提供了重要参考依据。
[Abstract]:Objective to investigate the value of real-time elastography quantitative analysis technology of RTE in lean body mass and application value for the disease population. Analysis of 60 cases of chronic kidney disease patients and 60 healthy kidney hardness RTE application methods, 12 elastic variables, including blue field percentage (% AREA), complexity (COMP). The mean strain (MEAN), standard deviation (SD), contrast (CONT), parity (ENT), kurtosis, skewness (KURT) (SKEW), correlation (CORR), consistency (ASM), entropy (IDM), B/A (strain than renal cortex and psoas muscle hardness hardness strain ratio B/A), analyze the differences between the 12 elastic characteristics between the case group and the healthy group. The renal elastic image features between the two groups was not statistically significant in equality and difference, other elastic variables showed significant differences (P0.05). The 12 elastic properties were studied by Logistic regression analysis, obtained should Variable ratio B/A is the most important diagnostic parameter for chronic kidney disease. Conclusion RTE technology has a high application value for chronic lean nephropathy and provides important reference for clinical diagnosis.
