摘　　要：【目的】探讨实时超声造影技术在腹膜后占位性病变中的诊断价值。[方法]30例腹膜后占位性病变按照病理结果分为两组：良性病变10例为良性组，恶性病变20例为恶性组。两组患者分别行常规超声与超声造影检查，比较两组时间-强度曲线指标。【结果】与良性组比较，恶性组绝对峰值强度（API）、上升支斜率（AS）、半降时间（HT）均显著增加（P〈0．05），两组峰值时间（PT）、始增时间（AT）比较差异无统计学意义（P〉0．05）。常规超声诊断的漏诊率和误诊率分别为40．0％和20．0％，显著高于超声造影的时间-强度曲线AS与下降支形态及并联检测后漏诊率（15．0％）和误诊率（10．0％）。【结论】实时超声造影技术在腹膜后占位性良、恶性病变的诊断中有较高价值，值得临床推广应用。[Objective]To explore the diagnosis and differential value of real time contrast-enhanced ultrasound in retroperitoneal space-occupying lesions in patients. [Methods]A total of 30 cases of retroperitoneal space occupying lesions patients accorded to the pathological results divided into 10 cases of benign lesions （benign group） and 20 cases of malignant lesions （malignant group）. The two groups of patients underwent conventional ultrasound and contrast-enhanced ultrasound detection, analyzed time intensity curve, and compared check results and pathological results. [Results]Compared with the benign group, the AS, HT, and API in the malignant group were significantly greater （ P 〈0.05）. However, there was no significant difference between the two groups with AT and PT（ P 〉0.05）. Ultrasound diagnosis of missed diagnosis rate and the misdiagnosis rate was 40.0% and 20.00/00, respectively. The ultrasound contrast time intensity curve rising and descending form parallel detection and missed diagnosis rate and the misdiagnosis rates were 15.0% and 10.0 %, respectively. [Conclusion]Real time contrast-enhanced ultrasound can provide a basis for diagnosis and differential of retroperitoneal space occupying benign and malignant lesions, and has certain clinical value.
