目的探讨SonoLiver造影软件参数成像诊断法在诊断腹膜后肿块中的应用价值。方法使用SonoLiver软件分析60例腹膜后肿块超声造影动态过程，得出参数成像图，通过分析上升时间、达峰时间、平均渡越时间参数成像图的特征，提出参数成像诊断法。结果良性组时间相关性指标的参数成像颜色多显示为分界清晰，过渡明显，呈“片状”分布；而恶性组多表现为杂乱、颜色分界不清，呈“斑点状”分布。将参数成像诊断法与病理诊断结合得出计数配对资料，两种诊断方法的阳性率无统计学差异且吻合程度中等。结论将超声造影与参数成像法相结合是诊断腹膜后肿块的一种新方法。

Objective To investigate the diagnostic value of parametric imaging of contrast-enhanced ultrasound (CEUS) in retroperitoneal tumors using SonoLiver software. Methods Sixty cases of retroperitoneal tumors were analyzed by CEUS with SonoLiver software. The color-mapped images of timedependent indexes, such as rise time(RT), time to peak(TTP), mean transit time(mTT), were abserved in the regions of interests(ROIS). The degree of the coincidence between pathologic diagnosis and parametric imaging diagnosis was carefully study by comparing parametric images with histopathological findings.Results 1 ) There was statistical significance of RT, TTP and mTT between the benign and malignant retroperitoneal tumors. 2) The time-dependent parametric images were obvious different between benign lesions and malignant lesions. The malignant lesions enjoyed a confused boundary and distribute disorderly,while the benign tumors had a clear distribution. There was a good coincidence degree between pathologic diagnosis and parametric imaging diagnosis(κ =0. 625, P =0. 000). Sensibility, specificity, the rate of misdiagnosis and missed diagnosis, the degree of accuracy respectively was 85.3 ％, 76.9 ％, 23.1 ％, 14.7 ％,81.7％ by the new diagnosis method. Conclusions Parametric imaging is a very useful way of evaluating the level of blood flow with the tumors and provides a new vision in the diagnosis of retroperitoneal tumors. It demonstrates retroperitoneal tumors clearly and objectively.
