超声造影诊断腹膜后占位性病变的临床应用

Application of Contrast-enhanced Ultrasonography in the Differential Diagnosis of Retroperitoneal Occupying Lesions

目的:探讨实时超声造影技术对腹膜后占位性病变的诊断及鉴别诊断的价值。方法:对20例腹膜后占位性病变的患者应用新型声学造影剂声诺维进行超声造影检查,并做时间强度曲线分析,结果与病理结果对比。结果:超声造影能更准确地显示腹膜后占位性病变的血供情况以及组织坏死情况,良、恶性组造影感兴趣区强化程度、上升斜率及半降时间等指标的差别有显著性意义。结论:实时超声造影对腹膜后占位性病变的诊断及良恶性鉴别诊断具有一定的临床使用价值。

Objective： To evaluate the real-time contrast-enhanced uhrasonography （CEUS） in the differential diagnosis of retroperitoneal occupying lesions. Methods： Twelve patients with retroperitoneal occupying lesions were examined by pulse subtraction contrast-enhanced ultrasonography with a bolus injection of SonoVue. All lesions were confirmed by pathology. Results： Contrast-enhanced ultrasonography could reveal vascularity of retroperitoneal occupying lesions and retrieve insufficiency of color Doppler ultrasonography. Statistically significant differences were noted between the benign and malignant tissue in the values of AS,AA and HT. Conclusion： Contrast-enhanced ultrasonography is valuable in differential diagnosis of the retroperitoneal occupied lesions.
