Endoscopic ultrasound elastography: Current status and future perspectives

Table 1 Five score classification system for endoscopic ultrasound elastography

Score	Color pattern	Stiffness	Histology	Ref.
1	Green	Homogeneous soft	Normal pancreatic tissue	[6,34]
2	Green, yellow and red	Soft heterogeneity	Fibrosis	[6,34]
3	Mostly blue with minimal heterogeneity	Hard	Early pancreatic adenocarcinoma	[6,34]
4	Central green hypoechoic region and blue tissue outer layer	Hard	Neuroendocrine tumor, metastasis	[6,34]
5	Blue lesions with heterogeneity due to necrosis	Hard	Advanced pancreatic adenocarcinoma	[6,34]
