Liver ultrasound

The ultimate solution for liver assessment

It’s no secret that liver disease is a growing health concern.

Globally, liver disease accounts for around 2 million deaths per year, with around 1 million of those due to cirrhosis and 1 million due to viral hepatitis and hepatocellular carcinoma. Unhealthy lifestyle choices like obesity, alcohol and drug use are the root causes of the disease and in most cases, liver disease can be prevented¹.

For decades, liver biopsy has been the conventional method for disease assessment, and more recently MR Proton Density Fat Fraction (MR-PDFF) has been added to measure liver fat. This method, however, presents several patient barriers including the pain of biopsy, access to MR imaging, high cost and long wait times.

This is where Philips comes in. Thanks to innovations to Philips EPIQ & Affiniti ultrasound systems there is now a comprehensive solution to support the assessment, treatment and monitoring of liver disease, with four key features working together in one effective tool.

Quantitative parameters for assessment of steatosis

with Philips Liver Fat Quantification (LFQ) tools.

Easy, fast and robust acquisition

with ElastQ imaging.*

29% to 85% reduced pain and fatigue

from scanning with the C5-1 transducer compared to conventional transducers.

*Side-by-side view of unique imaging confidence and stiffness maps helps reduce workflow steps and allows for simultaneous map correlation during acquisition and measurement phases.

The widespread use of this technology in a general population could be helpful in screening for advanced chronic liver disease, especially considering that a complete study can be done in under three minutes using a non-invasive method for chronic liver disease.”

Easy quantifiable tools to assess liver health

ElastQ imaging

ElastQ provides a 2D shear wave (2D-SWE) real-time assessment of tissue stiffness that is noninvasive, reproducible, and easy to perform. ElastQ also includes the ability to make retrospective measurements on stored images and includes a confidence map for adequate shear wave propagation display.

ElastPQ imaging

ElastPQ is a point shear wave (pSWE) method of obtaining tissue stiffness values of the liver. Using real-time imaging as a guide, the ROI is placed over the area of interest and tissue stiffness data is acquired in seconds. Multiple samples can be recorded and generated into a liver report.

Attenuation imaging

Attenuation Imaging can measure the amount of fat present in the liver by calculating the attenuation coefficient of sound absorbed by the liver parenchyma. This method provides quantitative attenuation parameters that can help assist physicians in the management of patients with hepatic steatosis.

HRI imaging

HRI imaging technology compares the relative brightness of the liver parenchyma to the kidney and provide fast, quantifiable liver steatosis information.

Contrast enhanced liver ultrasound

Ultrasound contrast agents can transform the role of ultrasound, allowing clinicians to study the enhancement patterns of liver lesions in real time. With Philips ultrasound, contrast enhanced ultrasound is seamlessly integrated into the standard workflow.

Image fusion and navigation

Make confident decisions even in challenging diagnostic cases with Philips image fusion and needle navigation capabilities. Streamlined workflow allows clinicians to achieve fast and effective fusion of CT/MR/PET with live ultrasound while needle navigation aids in guiding biopsy of small and difficult-to-access lesions².

Using Tumor contour, users can plan and target lesions with a semi-automated tool that helps outline a 3D contour around a structure of interest, potentially improving procedure guidance with challenging cases where the lesion may not be easily visualized.

Transducers created to image all body habitus

People come in many different shapes and sizes, with PureWave crystal technology you can improve penetration in difficult to scan body types, all while maintaining excellent detail resolution, Doppler sensitivity and contrast enhanced ultrasound (CEUS) performance.

PureWave crystal technology is the biggest breakthrough in piezoelectric transducer material in 40 years and is 85% more efficient than conventional piezoelectric materials, resulting in exceptional performance for all patient body types.
