Contrast-enhanced harmonic EUS and EUS elastography according to diseases

Enhanced EUS according to disease	Contrast-enhanced harmonic EUS	EUS elastography (strain elastography)
Solid lesion
Pancreatic cancer	Hypovascular enhancement	Heterogeneous blue pattern
Inflammatory tumor	Isovascular enhancement	Green to blue pattern according to the degree of fibrosis
Endocrine tumor	Hypevascular enhancement	Homogeneous blue pattern
Cystic lesion
IPMN
Mucus clot	Absence of vascularity
Mural nodule	Presence of vascularity
Lymph node
Malignant	Heterogeneous enhancement	Blue pattern
Benign	Homogeneous enhancement	Red to green pattern
Liver metastasis	Absence of vascularity in Kupffer-phase imaging

EUS, endoscopic ultrasonography; IPMN, intraductal papillary mucinous neoplasm.
