目的:探讨声速匹配技术在评价肾功能不全肾实质纤维化中的价值。方法:使用超声的声速匹配成像技术检测95例受检者左肾实质,包括对照组30例,肾功能不全组32例,慢性肾衰组33例。分2步完成测量过程:首先调整取样框,包含部分肾实质,测得声速匹配值V1,然后缩小取样框,不包含肾实质,完全为肾周的结缔组织,测得声速匹配值V2,检查结束后,静态分析,分别测量取样框的面积S1和S2,利用公式计算三组间的肾实质的声速匹配值。结果:对照组、肾功能不全组和慢性肾衰竭组,三组间肾实质肾实质匹配值比较均P<0.05,有统计学差异;三组间肾周组织声速匹配值比较均P>0.05,无统计学差异;选区声速匹配指数对肾功能不全组检出率明显高于常规超声,P<0.001。结论:选区声速匹配指数技术可以有效检测肾功能不全肾脏纤维化程度。
Objective: To investigate the value of sound velocity matching in the evaluation of renal insufficiency renal parenchymal fibrosis. Methods: The left renal parenchyma was detected in 95 subjects using sonographic matching technique, including 30 cases in control group, 32 cases in renal dysfunction group and 33 cases in chronic renal failure group. The measurement process is completed in two steps: First, adjust the sampling frame to include part of the renal parenchyma, and measure the sound velocity matching value V1, and then narrow the sampling frame to exclude the renal parenchyma, completely the connective tissue of the kidney, and measure the sound velocity matching value V2; check After the static analysis, the area S1 and S2 of the sampling frame were measured, and the formula for calculating the sound velocity matching value of the renal parenchyma was calculated. Results: Compared with the control group, renal insufficiency group and chronic renal failure group, the parenchymatous matching values of renal parenchymal kidney in the three groups were all significantly lower than P <0.05, the difference was significant (P> 0.05) No significant difference; the sound velocity matching selection index detection rate of renal insufficiency was significantly higher than conventional ultrasound, P <0.001. CONCLUSIONS: The sound velocity matching index technique can effectively detect the degree of renal fibrosis in patients with renal insufficiency.
