摘要
目的探讨三维超声联合断层超声成像(TUI)和容积空间对比成像(VCI)技术诊断肝实性肿瘤的价值。方法对50个肝实性肿瘤病灶分别进行二维超声与三维超声联合TUI、VCI检查,评价两种技术对病灶的显示能力。以手术或穿刺活检的病理结果作为金标准,对二者诊断的准确率进行比较,对比分析两种方法对肝恶性肿瘤诊断的敏感度、特异度、准确率、阳性预测值、阴性预测值。结果二维超声诊断与病理诊断的符合率为68.00%(34/50),三维超声联合TUI、VCI技术诊断与病理诊断的符合率为90.00%(45/50,P<0.05);三维超声联合TUI、VCI技术诊断肝恶性肿瘤的敏感度为91.67%(33/36)、特异度为85.71%(12/14)、准确率为90.00%(45/50)、阳性预测值为94.29%(33/35)、阴性预测值为80.00%(12/15),其敏感度、准确率、阴性预测值与二维超声诊断肝恶性肿瘤比较差异有统计学意义(P均<0.05)。结论三维超声联合TUI、VCI技术能够提供更全面、更丰富的诊断信息,对定性诊断肝脏肿瘤有较高的临床应用价值。
Objective To investigate the value of 3D ultrasound combined with tomographic ultrasound imaging （TUI） and volume contrast imaging （VCI） in diagnosis of liver solid masses. Methods A total of 50 solid liver masses underwent 3D ultrasound combined with TUI and VCI as well as 2D-ultrasound, respectively. The displaying ability of lesions of these technologies were evaluated. The pathological findings from the surgery or biopsy were taken as gold standards. The coin- cidence rate with pathology, and the sensitivity, specificity, accuracy, positive predictive rate and negative predictive rate were compared between 3D-ultrasound combined with TUI and VCI and 2D-ultrasound. Results The coincidence rate with pathology for 2D-ultrasound was 68.00% （34/50）, for 3D-ultrasound combined TUI with and VCI was 90.00% （45/50, P〈0.05）. The sensitivity, specificity, accuracy, positive predictive rate and negative predictive rate of 3D-ultrasound combined with TUI and VCI was 91.67% （33/36）, 85.71% （12/14）, 90.00% （45/50）, 94.29% （33/35） and 80.00% （12/15） in diagnosis of liver cancer, respectively, and the sensitivity, accuracy and negative predictive rate were superior to those of 2D-ultrasound （all P〈0. 05）. Conclusion 3D-ultrasound combined with TUI and VCI can provide comprehensive and plentiful diagnostic information for clinicians, which has higher value in qualitative diagnosis of liver tumor.
