[摘要] 目的：探讨超声造影对脾血管瘤的诊断价值。方法：应用造影匹配成像(CnTI)技术及造影剂声诺维(SonoVue)对8例18个脾血管瘤进行超声造影检查，观察注射造影剂后病灶增强表现。结果：18个脾血管瘤开始增强时间为7～18 s，平均(11.94±2.75) s，始增时间较周围脾实质早，达峰时间和始消时间较周围脾实质晚，差异均有统计学意义(P<0.05)，其中11个(61.1%)病灶呈周边环状增强，后逐渐向心性充填，6个(33.3%)病灶呈整体快速高增强，后持续等增强，1个(5.6%)病灶呈树枝样强化，后不均匀高强化。结论：超声造影能较好地显示微循环灌注，对临床诊断脾血管瘤具有重要意义。

[Abstract] Objective: To discuss the diagnostic value of contrast-enhanced ultrasound(CEUS) in the splenic hemangiomas. Methods: 18 lesions in 8 patients with splenic hemangiomas were underwent contrast-enhanced ultrasound examination by using contrast tuned imaging (CnTI) technology and SonoVue. Enhancement patterns of hemangiomas were observed. Results: The contrast-enhancement time of splenic hemangiomas was 7-18 s, averaging (11.94±2.75) s. Compared with the peripheral splenic parenchyma, all lesions were enhanced earlier, the time to peak and the washout time of the hemangiomas were longer. There were significant differences between the two groups in all the data mentioned above (P<0.05). Among the 18 lesions, 11 (61.1%) lesions showed peripheral enhancement and centripetal fill-in; 6(33.3%) lesions showed homogeneous hyper-enhancement very fast, then iso-enhancement continuely; 1 (5.6%) lesion first appeared with branches and successively appeared inhomogeneous hyper-enhancement. Conclusion: It is quite valuable to adopt contrast-enhanced sonography examination for diagnosis of splenic hemangioma.

近年来，随着超声造影技术的发展及SonoVue的应用，肝、肾等疾病的超声造影诊断已取得较为满意的效果。超声造影在脾脏疾病的应用方面研究报道却较少。本研究分析了8例脾血管瘤的超声造影增强特点，旨在探讨超声造影在脾血管瘤诊断中的应用价值。
1 资料与方法
1.1 一般资料
收集2008年12月～2011年1月就诊于本院的脾血管瘤患者8例共18个病灶，8例患者中，男性3例，女性5例，年龄39～79岁，平均(54.3±16.8)岁，病灶大小0.7～4.8 cm，平均(1.7±1.1) cm，二维声像图病灶呈高回声16个，低回声2个。其中2例经脾穿活检，2例经手术切除得到病理诊断，4例经增强CT或MRI并常规超声随访6个月以上证实为脾血管瘤。
1.2 仪器与方法
使用Esaote My Lab 90型彩色多普勒超声仪 ......
