【摘要】 目的探讨声触诊组织量化技术(virtual touch tissue quantification,VTQ)在肾实性肿瘤诊断中的临床应用价值。方法应用VTQ技术,对57例60个肾实性肿瘤及其肾皮质进行检测,获得病灶及其周围距病灶1.0 cm以上的肾皮质剪切波速度(shear wave velocity,SWV),与35例健康志愿者肾皮质SWV进行对比,比较良恶性病灶、病灶和周围肾皮质的SWV值及病灶组与健康志愿者肾皮质SWV值。结果经病理或超声造影、CT、MRI中任意两项增强影像学诊断60个病灶,其中良性病灶27个、恶性病灶33个,良性病灶与周围肾皮质SWV值比较差异有统计学意义,而恶性病灶与周围肾皮质、良恶性病灶及病灶组与健康志愿者肾皮质SWV值比较差异均无统计学意义,其中肾透明细胞癌与肾血管平滑肌脂肪瘤最为常见,两者SWV值比较差异有统计学意义。结论 VTQ技术可评价肾实性肿瘤的硬度,在常见肾实性肿瘤的定性诊断中有一定应用价值。更多还原

【Abstract】 Objective To investigate the clinical Application value of virtual touch tissue quantification(VTQ) in the diagnosis of renal solid tumors.Methods VTQ was applied in 57 cases of 60 renal solid tumor and renal cortex to measure the shear wave velocity(SWV) of the lesions and the surrounding lesions with a distance of more than 1.0cm.And the SWV was compared with the renal cortical SWV of 35 healthy volunteers.The ratio of SWV between benign and malignant lesion,and the ratio of SWV of the lesion and its renal cortex and of healthy volunteers were compared separately.Results 60 lesions confirmed by pathology or CEUS,CT,MRI in any two enhancement imaging,27 benign lesions,malignant lesions 33.The benign lesions and the corresponding renal cortex SWV value had significant difference,While the malignant lesions and surrounding renal cortex,benign and malignant lesions and renal cortex lesion group and healthy volunteers of renal cortical SWV values were not significant.Renal clear cell carcinoma and renal angiomyolipoma is the most common renal solid tumors,SWV value of the difference between the two was statistically significant.Conclusions VTQ technology can evaluate the hardness of solid tumors of the kidney,there is a certain value in common solid tumors of renal qualitative diagnosis.更多还原
