摘要 目的探讨声触诊组织成像定量技术(virtual touch tissue imaging quantification,VTIQ)与常规超声在乳腺良恶性结节中应用价值。方法选取扬州大学附属医院2017年5月—2019年12月收治的乳腺恶性结节患者54例(恶性组),同期收治的125例乳腺良性结节患者(良性组)。所有受检者均分别接受VTIQ与常规超声检查,统计恶性组及良性组、恶性组不同病理分期及不同分化程度患者超声参数[血流搏动指数(PI)、阻力指数(RI)、收缩期峰值血流速度(PSV)]、剪切波速度(SWV),并分析比较超声参数、SWV与疾病分期、分化程度关联性、超声及VTIQ对乳腺结节诊断效能。结果恶性组PI、RI、PSV、SWV高于良性组,差异有统计学意义(P<0.05);不同病理分期乳腺恶性结节患者PI、RI、PSV、SWV比较,差异有统计学意义(P<0.05),且随疾病分期增高,PI、RI、PSV、SWV呈增高趋势(P<0.05);不同分化程度患者PI、RI、PSV、SWV比较,差异有统计学意义(P<0.05),且随分化程度增高,PI、RI、PSV、SWV呈降低趋势(P<0.05);PI、RI、PSV、SWV与乳腺恶性结节病理分期存在正相关关系,与分化程度存在负相关(P<0.05);VTIQ对乳腺结节诊断敏感度(94.44%)、特异度(97.60%)、准确度(96.65%)高于常规超声(79.63%、88.80%、86.03%),差异有统计学意义(P<0.05)。结论乳腺良恶性结节患者VTIQ及常规超声相关参数存在显著差异,各参数与乳腺恶性结节病理分期、分化程度具有密切关联性,可通过其对疾病进行良恶性质鉴别诊断,且VTIQ诊断效能更高。 Objective To investigate the value of virtual touch imaging quantification(VTIQ)and conventional ultrasound in benign and malignant breast nodules.Methods From May 2017 to December 2019,54 patients with malignant breast nodules from the Affiliated Hospital of Yangzhou University were selected as the malignant group,and 125 patients with benign breast nodules were as the benign group.All the subjects were examined by VTIQ and conventional ultrasound respectively.The ultrasonic parameters(PI,RI,PSV and SWV)of patients with different pathological stages and different degrees of differentiation in the malignant group,benign group and malignant group were statistically analyzed.The diagnostic efficacy of ultrasonography and VTIQ in breast nodules were compared.Results The PI,RI,PSV and SWV in the malignant group were higher than those in the benign group(P<0.05).The differences of PI,RI,PSV,and SWV in the patients with malignant breast nodules at different pathological stages were statistically significant(P<0.05),and the values of them increased with the disease stage(P<0.05).Comparison of PI,RI,PSV,and SWV in the patients with different degrees of differentiation showed statistically significant differences(P<0.05),and as the degree of differentiation increased,PI,RI,PSV,and SWV decreased(P<0.05).The PI,RI,PSV,and SWV were positively correlated with the pathological stage of malignant breast nodules,and negatively correlated with the degree of differentiation(P<0.05).The sensitivity(94.44%),specificity(97.60%),and accuracy(96.65%)of VTIQ for breast nodule diagnosis were higher than those of conventional ultrasound(79.63%,88.80%and 86.03%),and the differences were statistically significant(P<0.05).Conclusion There are significant differences in VTIQ and conventional ultrasound related parameters in the patients with breast benign and malignant nodules.Each parameter is closely related to the pathological stage and differentiation degree of breast malignant nodules.It can be used to differentiate the benign and malignant nature of the disease,and VTIQ has a higher diagnostic efficiency.
