Simplify liver assessment with noninvasive tools

Obtaining liver stiffness measurements with Philips shear wave elastography is surprisingly easy and fast even on difficult-to-image patients. It’s noninvasive, making it a quick, simple step for sonographers and virtually painless for patients.

What is it?
Philips elastography generates shear waves inside the liver by using acoustic force from a focused ultrasound beam. The system monitors shear wave propagation and measures its velocity, then displays it in a format that is easy to interpret.

Noninvasive liver assessment made easy

The liver stiffness measurement is captured in seconds through a simple noninvasive scan

Easily assess and monitor patients

When do you use it?

Liver shear wave elastography provides stiffness measurements for assessment of diffuse liver diseases and neoplastic lesions of the liver. It is noninvasive, so for some patients, shear wave elastography can turn painful, expensive biopsies into a well-tolerated method for follow up and monitoring of the disease.

How long does it take?

Perform a right intercostal scan of the liver, set the ROI between 1 and 2 cm below the liver capsule avoiding vessels, and at a total depth of <8 cm. Press ‘Update’. In less than a second, the measurement results are displayed on the image. It is that easy and fast. So fast, in fact, you can add it to your routine abdominal scans for critical data early in the diagnostic process, and without compromising your lab schedule.

The image and measurement results are displayed, including the mean and median values, and the standard deviation, in kPa or m/s. If measurement reliability is low, 0.00 kPa will be displayed as the result. The Elastic Modulus E [kPa] is calculated using the equation E = 3ρVs where Vs [m/s] is defined as the shear wave propagation velocity and ρ as tissue density.
