方法：回顾性分析沈阳市第四人民医院2012-03/2015-05诊治的52例52眼眼眶球后肿瘤患者的超声造影资料，以病理结果分为良性肿瘤组41眼，恶性肿瘤组11眼。应用SonoLiver软件分析造影资料，获得时间-强度(TI)曲线和定量数据。

结果：良性肿瘤组TI曲线多呈快进慢出模式，恶性肿瘤组TI曲线多呈快进快出模式。定量数据：恶性肿瘤组上升时间(RT)、平均渡越时间(mTT)低于良性肿瘤组(P<0.05)； 两组间峰值强度(IMAX)无差异(P>0.05)。

结论：超声造影可为眼眶球后肿瘤的鉴别诊断提供影像学依据，有助于术前的定性诊断。

METHODS: The contrast-enhanced ultrasound data of the 52 patients(52 eyes)with orbital retrobulbar tumors in the Fourth People's Hospital of Shenyang from March 2012 to May 2015 were retrospectively analyzed. According to the pathological results, 41 eyes were divided into benign group and 11 eyes were malignant group. The time intensity(TI)curve and quantitative data were obtained by SonoLiver software.

RESULTS: The TI curve of benign group mainly showed fast in and slow out mode, while that of malignant group mainly showed fast in and fast out mode. Quantitative data: rise time(RT)and mean transit time(mTT)in malignant group were lower than those in benign group, while there was no significant difference in maximal intensity(IMAX)between the two groups(P>0.05).

CONCLUSION: Contrast-enhanced ultrasound can provide imaging basis for the differential diagnosis of orbital retrobulbar tumors which is helpful for the preoperative qualitative diagnosis.
