Ultrasound elastography (USE) of the pancreas allows pancreatic tissue stiffness assessment by virtual palpation. Two main types of USE are used. For the pancreas strain elastography applying by endoscopic ultrasound has been established for the characterisation of small solid pancreatic lesions (SPL). In larger SPL >30 mm the results are less convincing mainly due to the heterogenicity of the lesions but also by concomitant changes of the surrounding pancreatic parenchyma. The current role of shear wave elastography has to be determined. This article reviews the current use of elastography of the pancreas.
胰腺的超声弹性成像(USE)可通过虚拟触诊评估胰腺组织硬度。主要使用两种类型的USE。对于胰腺,经内镜超声应用的应变弹性成像已用于小的实性胰腺病变(SPL)的特征描述。在大于30mm的较大SPL中,结果不太令人信服,主要是由于病变的异质性,也由于周围胰腺实质的伴随变化。剪切波弹性成像的当前作用有待确定。本文综述了胰腺弹性成像的当前应用。
