SuperSonic Imagine introduces UltraFast Doppler technology


SuperSonic Imagine, the ultrasound company that pioneered breakthrough ShearWave™ Elastography technology, today announced another major breakthrough in ultrasound imaging: UltraFast™ Doppler. The company, based in Aix-en-Provence, France, unveiled this revolutionary technology at the World Federation for Ultrasoundin Medicine and Biology, Euroson and Ultraschall Meeting.
Color Flow Imaging and Pulsed Wave Doppler are well-established ultrasound tools that analyze blood flow and are critical to cardiovascular disease assessment and cancer diagnosis.
On Aixplorer's fully patented UltraFast imaging platform, UltraFast Doppler unites Color Flow Imaging with Pulsed Wave Doppler. The result is never-seen-before ultra-high frame rate Color Flow clips that are up to ten times faster than conventional Color Doppler. Remarkably, the same technology also acquires fully quantifiable Doppler data throughout the Color box, enabling the generation of post-processed Pulsed Wave Doppler spectra from multiple locations in the same image.
These new advances in Doppler technology introduce a new era of flow imaging, workflow efficiency and diagnostic confidence.
Peter Burns, Professor of Medical Biophysics at the University of Toronto and Senior Scientist at Sunnybrook Health Sciences Centre, Toronto commented, "This technology promises to overcome two challenges faced by vascular sonographers every day when they use conventional duplex scanners. First, conventional color frame rates are too low to show real arterial hemodynamics, with pathology often masked by aliasing artifacts and second, the pulsed Doppler examination is a separate and time consuming process of searching for the optimal signal. UltraFast Doppler provides high frame rates, less aliasing and the ability to show spectra at every point in a stored color loop. It provides more accurate flow imaging and will enable more effective workflow in the vascular lab."

Validation of Clinical Benefits of ShearWave Elastography


Press release March 5th, 2011


SuperSonic Imagine Reports Validation of Clinical Benefits of ShearWaveTM Elastography, Demonstrating Increased Performance in Breast Cancer Diagnosis. Study Results with validation on European Sub-Population were presented at the European Congress of Radiology (Vienna )on March 4th during a conference symposium.

March 5th, 2011 (Aix-en-Provence, France). SuperSonic Imagine presented yesterday the validation of a world wide multicentre study, based on European recruitment, confirming the benefit of ShearWave Elastography when added to ultrasound for improved lesion classification.

Launched by SuperSonic Imagine in June 2008, the global, multi-centre study was conducted across 16 American and European sites involving 1,800 patients with breast lesions.

The first major result of this study demonstrated that ShearWave Elastography is reproducible both quantitatively and qualitatively. This reproducible technology provides strong assurance of precise tissue evaluation during diagnosis and is expected to be also useful in follow-up.

The second important outcome is a statistical model based on 939 lesions, which showed that ShearWave Elastography increases the performance of ultrasound breast cancer diagnosis. The addition of ShearWave Elastography features, such as maximum elasticity (stiffness) or heterogeneity (uniformity) of a lesion, to B-mode ultrasound, would permit an improvement in the BI-RADS® classification accuracy, (standardization tool for breast lesion classification from the American College of Radiology) improving breast diagnosis.

European results validate the conclusions of the model

In Europe, 1,223 lesions have been examined, including 425 cancers (34.8%) The European study was conducted across four sites in France (332 lesions), four sites in Germany (585 lesions), one site in Italy (104 lesions) and one site in United-Kingdom (202 lesions).

The application of the model to this sub-group demonstrates the importance of the maximum elasticity value. When added to the BI-RADS® score, this value:
- Maintains the sensitivity* of the ultrasound exam (97.9%) 
- Increases its specificity* by more than 8 per cent (59.9% to 68.2%) 
- Maintains its negative predictive value* above 98% 
- Increases its positive predictive value* by more than 5 per cent (73.1% to 78.5%)

These results confirm the increase in specificity expected with the addition of ShearWave Elastography features to BI-RADS® criteria and consequently the reduction of the rate of negative biopsies. In addition, ShearWave Elastography can assist in diagnosing cancers that would have otherwise fallen into a follow-up category, thus earlier intervention and treatment could occur with significant implications for patient management.

*Note: Sensitivity = ability to find malignant lesions 
Specificity = ability to find benign lesions 
Negative predictive value = reliability of the benign test 
Positive predictive value = percentage of lesions correctly classified

About Aixplorer®:
Aixplorer is a next-generation ultrasound imaging system with unique technology that offers advantages in lesion detection and characterization. Using a method of imaging called ShearWaveTM Elastography, Aixplorer can measure true tissue elasticity, in real time, providing quantifiable*, user- skill independent and reproducible results. The Aixplorer ultrasound system also provides impeccable images and sophisticated features all packaged in an ergonomic design, to assist in the imaging diagnostic process. Based on these innovations, Aixplorer now has six clinical applications: breast (and 3D breast), thyroid, abdomen, musculo- skeletal, prostate, and gynaecological (excluding obstetrics). In parallel to diagnostic imaging, researchers at SuperSonic Imaging are currently developing a noninvasive ultrasound therapy method, based on technology from Miroir à Retournement Temporel developed by Mathias Fink, a co-founder of SuperSonic Imagine. Aixplorer was named after its birthplace, Aix-en-Provence, in France. The Aixplorer has both CE mark approval since 2008 and FDA clearance since 2009.
