What do you call the non-invasive assessment of liver stiffness using ultrasound?

The non-invasive assessment of liver stiffness using ultrasound is referred to as elastography. This technique utilizes high-frequency sound waves to measure how easily the liver deforms in response to applied pressure, which helps in assessing liver fibrosis or cirrhosis. Elastography is advantageous because it can provide valuable insights into liver health without the need for invasive procedures such as biopsies.

In contrast, echocardiography primarily focuses on the assessment of heart structures and functions, making it unrelated to liver stiffness measurement. Sonohysterography is a procedure that examines the uterus using ultrasound, and fluoroscopy is a technique that uses X-rays to obtain real-time moving images of the interior of the body, which does not pertain to liver assessment. Thus, elastography stands out as the correct terminology for this specific non-invasive evaluation of liver stiffness.
