Overview of various types of potential vascular CEUS applications grouped into four categories

	Type
Luminal applications	Grading stenosis (e.g., carotid artery)
	Occlusion vs. pre-occlusive stenosis
	Detection of superficial plaque irregularities and ulceration
Characterization of intraluminal pathology	Evaluation of atherosclerotic intraplaque neovascularization
	Characterization of portal vein thrombus
	Characterization of venous thrombus in peripheral veins
Evaluation of the vascular wall	Qualitative and quantitative evaluation of wall vascularity in inflammatory conditions (e.g., aortitis, TIPIC)
Investigation of potential extravascular leakage	Endoleak detection after EVAR
	Pseudoaneurysm (e.g., peripheral arteries, parenchymal organs)
	Extravasation (e.g., aneurysm rupture, vascular injury)

CEUS, contrast-enhanced ultrasonography; TIPIC, transient perivascular inflammation of the carotid artery; EVAR, endovascular aortic repair.
