Echo-enhanced ultrasound is a newly available mode of imaging for differential diagnosis of pancreatic tumours. Ductal carcinomas are often hypovascularised compared with the surrounding tissue. Neuroendocrine tumours, on the other hand, are hypervascularised lesions. Tumours associated with pancreatitis have a different vascularisation pattern depending on inflammation and necrosis. Cystadenomas frequently have many vessels along the fibrotic strands.
Data from prospective studies have demonstrated, on the basis of these imaging criteria, that the sensitivity and specificity of echo-enhanced sonography for differentiation of pancreatic masses are >or=85 and >or=90%, respectively.
Pancreatic tumours have a different vascularisation pattern in echo-enhanced ultrasound. These characteristics can be used with high diagnostic accuracy for differential diagnosis.
超声造影是一种新出现的用于胰腺肿瘤鉴别诊断的成像模式。与周围组织相比，导管癌通常血供不足。另一方面，神经内分泌肿瘤是血供丰富的病变。与胰腺炎相关的肿瘤根据炎症和坏死情况有不同的血管化模式。囊腺瘤通常在纤维条索周围有许多血管。
前瞻性研究的数据表明，基于这些成像标准，超声造影鉴别胰腺肿块的敏感性和特异性分别≥85%和≥90%。
在超声造影中，胰腺肿瘤有不同的血管化模式。这些特征可用于鉴别诊断，诊断准确性高。
