What is contrast-enhanced ultrasound used for?

Contrast-enhanced ultrasound can be used to image blood perfusion in organs, measure blood flow rate in the heart and other organs, and for other applications.

What is contrast-enhanced imaging?

Contrast-enhanced ultrasound (or CEUS) brings together two imaging tools: ultrasound and contrast agents. The combination of these two techniques creates accurate, detailed images of internal organs. Here at UVA Health, CEUS can often replace CT scans or MRIs of the liver, kidneys, or bladder in children and adults.

What is a disadvantage of using contrast-enhanced ultrasound?

requires only 0.2 ml per injection and six or seven injections may be given during a single exam). Thus this modality is most often used as a problem-solving technique, rather than as a surveillance tool. Currently, the primary disadvantage of CEUS is the lack of availability of this modality in clinical practice.

When was contrast used in the ultrasound?

Abstract. Initial reports from the 1960s describing the observations of ultrasound contrast enhancement by tiny gaseous bubbles during echocardiographic examinations prompted the development of the first ultrasound contrast agent in the 1980s.

What’s contrast-enhanced ultrasound imaging CEUS What are the applications of CEUS in medical ultrasound?

The basic role of CEUS is in enhancing the imaging of vessels on a macro and micro level to better classify pathological lesions like atherosclerosis. CEUS is also used in identifying tumor lesions by observing for angiogenesis and monitoring tumors post treatment for remission and relapses.

What contrast agent is used in ultrasound?

SonoVue is a purely intravascular contrast agent, therefore it allows assessment of the vascularity and non-specific contrast agent retention of lesions. Due to its widespread approval, it is by far the most commonly utilized ultrasound contrast agent currently.

What are the applications of CEUS in medical ultrasound?

What causes contrast in ultrasound?

Contrast agents This phenomenon arises because the impedance for ultrasound in gas is markedly different from that for soft tissue. Impedance is the product of density and propagation speed, and it can be appreciated that impedance in air is low whereas that in soft tissue is high.
