International Classification:

A61B 8/14

US Classification:

600458, 600437, 600462

Abstract:

A method and system for quantifying the extent of vaso vasorum with contrast enhanced ultrasound and correlating that quantitative value to the risk for vascular disease is provided. An ultrasound contrast agent is administered to a subject and images are obtained using an imaging method that identifies the uptake of the contrast agent by tissues. The amount of uptake is measured and the corresponding signal intensity change correlated with the amount of vaso vasorum present. Additionally, deformations of the vasculature are measured from the series of ultrasound images and this information is coupled with the quantification of the vaso vasorum to determine a risk index indicative of a subject's risk to vascular disease.

International Classification:

A61B 8/06

US Classification:

600454, 600458

Abstract:

A method for identifying blood flow patterns based on contrast-enhanced ultrasound imaging and, in particular, echocardiography. The method includes indicating a blood flow type in the cavity through which imaged blood is flowing by correlating the identified blood flow pattern with a selected pattern. Further, a report indicative of a condition of the cavity can be generated based on the indicated blood flow type.
