Personalized Liver Ultrasound

With chronic liver disease on the rise worldwide, the diagnosis of liver disease, including cancer, is critical, as further complications can arise. Key factors in helping to ease this global burden are early diagnosis, treatment, and continued patient monitoring. Personalized Liver Ultrasound solutions leverage a patient-centric approach to chronic liver disease with advanced, easy-to-use technologies such as contrast-enhanced ultrasound, fusion imaging, and Virtual Touch elastography.  

Virtual Touch Elastography​

The ACUSON Sequoia system was purpose-built with design elements to advance the state of elastography and deliver rapid, reliable, reproducible results. Dedicated hardware in the dual linear transmitter provides sustainable Acoustic Radiation Force Impulse (ARFI) imaging technology push energy over a deeper range. Robust tracking of stronger, more uniform shear wave measurements can now be achieved at deeper depths to help overcome patient dependent variability. ​
pSWE Liver

pSWE

Increased confidence in measurement accuracy is provided with a complete liver assessment report that includes the Interquartile Range (IQR) / Median Ratio, the recommended quality control measure for adequate technical quality. ​

2D SWE

2D SWE

In 2D SWE, high sampling density provides high spatial and stiffness resolution for imaging focal lesions and heterogenous tissue. Measurements can then be performed at precise locations to measure tissue stiffness in m/s or kPa.​

DAX for challenging patients by Dr. Richard G. Barr

The DAX transducer was designed to go to deep, imaging down to 40cm with elastography, CEUS and Fusion capabilities. Ergonomically designed, DAX also decreases the push force by 70% reducing potential injuries1, making DAX an ideal transducer for technically difficult patients with limited imaging windows.

Contrast-enhanced Ultrasound (CEUS) ​

The powerful architecture of the ACUSON Sequoia system allows visualization of contrast deeper and with greater clarity than ever before.​

Education & Training

Each patient presents with their own unique set of signs and symptoms. The gold standard for diagnosing and monitoring the progression of liver fibrosis is liver biopsy. Yet, there are known limitations of a liver biopsy that make it less than ideal for ongoing assessment of disease progression. Studies have shown an increase in stiffness due to liver disease, as measured with point shear wave elastography (pSWE), to be rapid, reliable, and reproducible. This course focuses on changes to liver stiffness due to chronic liver damage.

Learn about changes in shear wave velocity and elasticity with advancing liver disease.

Papers & Studies

Liver assessment using gray scale ultrasound findings alone can be difficult. Remove subjectivity to improve diagnostic confidence by displaying quantitative tissue stiffness properties using Virtual Touch technology.

The degree of tissue stiffness has been shown to correlate with the progression of liver fibrosis.

CEUS Liver

The DAX transducer provided visualization of an additional lesion at a much deeper level – a level that conventional contrast imaging struggles to see.

Contrast-enhanced ultrasound (CEUS) uniquely balances the sophisticated interaction between the contrast agent and the ultrasound wave. This technology harmonizes the vascularization and timing of liver perfusion, and leverages the expertise of the clinician and sophistication of the technology.

DAX Liver

Multiple metastatic lesions were demonstrated throughout the liver with the DAX – some well below 14 cm in depth.

The DAX transducer allows users to perform advanced applications such as contrast-enhanced ultrasound (CEUS), allowing contrast visualization to greater depths than conventional transducer technologies.
