A specialized ultrasound field using duplex imaging to evaluate arteries and veins throughout the body for stenosis, thrombosis, and aneurysm.

Another term for elastography — ultrasound-based mapping of tissue stiffness using compression or shear wave techniques.

The use of ultrasound guidance for minimally invasive procedures such as biopsies, aspirations, drainages, and injections.

Real-time co-registration of ultrasound with a pre-acquired CT or MRI dataset, allowing simultaneous side-by-side or overlaid display for lesion targeting.

A technique using focused ultrasound pulses to mechanically displace tissue and measure the resulting tissue response for stiffness assessment.

A quantitative elastography technique that measures tissue stiffness in kilopascals by tracking the speed of shear waves generated by acoustic radiation force.

An ultrasound technique that maps tissue stiffness, used to assess liver fibrosis and characterize breast and thyroid lesions.

Ultrasound that acquires a volumetric dataset allowing reconstruction in multiple planes and surface-rendered views.

Microbubble-based agents injected intravenously to enhance Doppler and tissue perfusion assessment on ultrasound.

A real-time display estimating the potential for mechanical bioeffects such as cavitation from the ultrasound beam.
