Echo-enhanced ultrasound with pulse inversion imaging: A new imaging modality for the differentiation of cystic pancreatic tumours

瞄准：在膀胱的胰腺的损害的鉴别诊断描述并且讨论提高回响的 sonography。方法：脉搏倒置技术(与 2.4 mL SonoVue 的静脉注射) 或在第二泛音成像的条件下面的 power-Doppler 模式(与 4 g Levovist 的静脉注射) 被用于提高回响的 sonography。结果：Cystadenomas 经常沿着纤维变性海滨显示出许多容器。在另一方面，包囊腺癌是糟糕并且混乱 vascularized。“年轻假包囊”经常被发现有一面高度脉管的 ised 墙。然而，“旧假包囊”的墙是糟糕 vascularized。从未来的研究的数据证明基于这些成像标准，在膀胱的胰腺的群众的区别的提高回响的 sonography 的敏感和特性是 】90% 。结论：膀胱的胰腺的群众在提高回响的 sonography 有一个不同血管形成模式。这些特征为他们的鉴别诊断是有用的，但是组织学仍然是标准答案。

AIM： To describe and discuss echo-enhanced sonography in the differential diagnosis of cystic pancreatic lesions. METHODS： The pulse inversion technique （with intravenous injection of 2.4 mL SonoVue） or the power-Doppler mode under the conditions of the 2^nd harmonic imaging （with intravenous injection of 4 g Levovist） was used for echo-enhanced sonography. RESULTS： Cystadenomas frequently showed many vessels along fibrotic strands. On the other hand, cystadenocarcinomas were poorly and chaotically vascularized. ＂Young pseudocysts＂ were frequently found to have a highly vascularised wall. However, the wall of the ＂old pseudocysts＂ was poorly vascularized. Data from prospective studies demonstrated that based on these imaging criteria the sensitivities and specificities of echoenhanced sonography in the differentiation of cystic pancreatic masses were 〉 90%. CONCLUSION： Cystic pancreatic masses have a different vascularization pattern at echo-enhanced sonography. These characteristics are useful for their differential diagnosis, but histology is still the gold standard.
