Shear wave elastography Simplify liver disease assessment

The value of elastography

Philips shear wave elastography simplifies liver assessment, making obtaining liver stiffness measurements fast and easy. This non-invasive, reproducible, and easily performed method of assessing liver tissue stiffness may help reduce, or even avoid, the need for conventional liver biopsies¹. Research suggests that instead of a costly and painful biopsy procedure, an easy ultrasound exam could become routine for assessing liver disease status.

Elastography in liver assessment:

ElastPQ (P-SWE) has proven valuable in staging liver disease, reducing the need for costly and potentially painful biopsies in some patients. ElastQ (2D-SWE) advances shear wave elastography, providing a technique that is not only noninvasive and easy to use, but also offers clinicians additional confidence in the reliability of measurements, even for the technically difficult patient (TDP), such as a patient with a high BMI.

ElastQ imaging

ElastQ imaging is a real-time, large Region of Interest (ROI), color-coded quantitative assessment of tissue stiffness. It is the only solution to offer both PureWave technology and high frame rate real-time shear wave imaging across abdominal applications. Clinicians can easily assess liver tissue stiffness using real-time feedback and make quantitative measurements with multiple sample points even retrospectively on DICOM stored images. Unique confidence map, used with the stiffness map, improve confidence of shear wave measurements. Both maps can be displayed side-by-side, which reduces workflow steps and allows for simultaneous map correlation during acquisition and measurement phases.

ElastPQ

ElastPQ is an easy-to-use method of obtaining tissue stiffness values of the liver on a predefined ROI. Using real-time imaging as a guide, the ROI is placed over the area of interest and tissue stiffness data such as AVG, MEAN, and IQR are obtained and displayed in seconds. Multiple samples can be recorded and liver tissue report generated from the results.

Noninvasive liver assessment made easy

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

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.
