超声造影诊断脾血管瘤价值的初步探讨

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7～18s,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。

Initial research for the diagnostic value of splenic hemangioma with contrast-enhanced ultrasound

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.
