Siemens Healthcare is presenting one of the most innovative technologies for its Acuson S2000 ultrasound system at the Medica from November 19 – 22, 2008 in Duesseldorf, Germany.
The Virtual Touch Tissue Imaging and Virtual Touch Tissue Quantification applications are the first commercially available implementations of ARFI (Acoustic Radiation Force Impulse). Similar to a physical palpation exam, these leading-edge applications represent a new dimension of diagnostic information by interrogating the mechanical strain properties or stiffness of tissue, which may be correlated with pathology.
Both applications are particularly suited to evaluating liver tissue. Additional fields of use – such as in prostate diagnosis – are currently clinically validated.
An examination using Virtual Touch technology is not only faster than conventional methods, it is also significantly more comfortable for the patient. Virtual Touch applications can provide physicians with information that could previously only be obtained via a biopsy, an invasive procedure that is both time-consuming and stressful. Using Virtual Touch applications, tissue is compressed using acoustic energy enabling the evaluation of the mechanical properties of deep areas and the detection of changes in the tissue. Without any need for manual compression quantitative and qualitative information can be obtained.
Virtual Touch Tissue Imaging and Virtual Touch tissue quantification are the first implementation of ARFI and are highly promising in identifying early stages of liver diseases causing cirrhosis. Early studies show that Virtual Touch Tissue Quantificaiton proved extremely sensitive in diagnosing fibrosis and distinguishing it from normal liver and cirrhosis. Dr. Mireen Friedrich-Rust at the Johann Wolfgang Goethe University Hospital in Frankfurt am Main, Germany, has found that “Virtual Touch Tissue Quantification is a promising procedure for quantifying the liver fibrosis stage using B mode controlled ultrasound in patients with viral hepatitis.” The new technology is already in use at several hospitals in Europe.Background information:
