摘　　要：目的:探讨声触诊(virtual touch tissues quantification,VTQ)在评估移植肾纤维化程度中的应用价值。方法:采用德国西门子公司生产的S2000彩色多普勒超声诊断仪独有的VTQ检测新技术检测54例移植肾,并与接受移植肾穿刺活检或手术切除的病理结果对照分析。结果:VTQ值与移植肾纤维化不同病理分期之间呈正相关(Spearman r=0.796,P<0.05)。结论:VTQ值可作为观测移植肾纤维化程度的无创定量观察新指标,能较好地评估移植肾的慢性损伤。Objective: To explore the value of virtual touch tissue quantification(VTQ) in the diagnosis of renal allograt fibrosis and analyze its advantages and limitations. Methods: The renal allografts of 54 patients with renal allograft biopsies or nephrectomy were assessed by Virtual Touch quantii cation of Siemens-Acuson S2000. Results: Stiffness of renal allograft was significantly correlated to the value of VTQ(Spearman r=0.796, P<0.05). Conclusion: VTQ is a new technique in the assessment of renal allograt i brosis.
