【摘要】：目的探讨声触诊组织定量(VTQ)技术诊断肝脏局灶性病变的临床价值。方法分析163个肝脏局灶性病变,行常规超声记录病灶的位置、长径、短径;应用VTQ技术记录病灶及其周围肝实质的剪切波速度(SWV)。采用ROC曲线评价VTQ技术鉴别良恶性病灶的诊断效能,采用多元线性逐步回归分析方法分析SWV值的影响因素。结果 (1)良恶性病灶间SWV值差异有统计学意义。以SWV=2.25 m/s为诊断界点,其灵敏度为90.1%,特异度为89.3%。(2)多元线性逐步回归分析显示病灶的病理类型是影响SWV的因素;而患者性别、年龄、病灶的位置、深度、长径、短径对SWV值无明显影响。结论 (1)VTQ技术能够较准确的鉴别肝脏良恶性病灶。(2)病灶的病理类型是影响SWV值的主要因素。
[Abstract]:Objective to evaluate the clinical value of acoustic palpation tissue quantification (VTQ) technique in the diagnosis of focal hepatic lesions. Methods 163 focal liver lesions were analyzed and the location, length and short diameter of the lesions were recorded by conventional ultrasound. VTQ technique was used to record the shear wave velocities of the lesions and their surrounding liver parenchyma. The ROC curve was used to evaluate the diagnostic efficacy of VTQ in differentiating benign and malignant lesions. Multivariate linear stepwise regression analysis was used to analyze the influencing factors of SWV value. Results (1) the difference of SWV value among benign and malignant lesions was statistically significant. SWV=2.25 m / s was taken as the diagnostic threshold. Multivariate linear stepwise regression analysis showed that the pathological type of the lesion was a factor affecting SWV, and the patient's sex, age, location, depth, length and diameter of the lesion, and the patient's sex, age, location, depth, length and diameter of the lesion. Conclusion VTQ technique can accurately differentiate the pathological types of benign and malignant liver lesions. The main factor affecting the SWV value is the short diameter.
