Available on the EPIQ and Affiniti platforms, shear wave elastography simplifies liver assessment, making obtaining liver stiffness measurements fast and easy. Philips ElastQ (2D-SWE) advances shear wave elastography, providing a technique that is not only non-invasive 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 is a non-invasive, reproducible and easily performed method of assessing liver tissue stiffness that may help reduce, or even avoid, the need for conventional liver biopsies. Research suggests that instead of a costly and painful biopsy procedure, an easy ultrasound exam could become routine for assessing liver disease status.1
With ElastQ shear wave elastography, 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 maps, used with stiffness maps, improve clinical 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.
ElastQ is so fast that you can add it to your routine abdominal scans for critical data early in the diagnostic process, and without compromising your lab schedule. Simply 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, and press “Update.” In less than a second, the measurement results are displayed on the image.
