Cardiac imaging

VisualSonics Inc., a leader in real time, in vivo, high-resolution micro-imaging systems and a wholly-owned subsidiary of SonoSite Inc., announced that its new VevoStrain™ software technology has been featured on the cover of the April issue of Circulation Research, Journal of the American Heart Association.

VevoStrain provides advanced imaging and quantification capabilities to study sensitive movements in the heart muscles particularly the myocardium. The VevoStrain technology enhances high-resolution imaging capabilities of high-frequency ultrasound with highly sensitive measurements of subtle variations in the myocardium. The VevoStrain software allows visualization of wall motions in the heart, including the entire heart as well as defined regions within the heart. Measurement capabilities include quantification of displacement, velocity, strain and strain rate. Researchers at Brigham and Women's Hospital, Harvard Medical School demonstrated the utility of VevoStrain technology as a non invasive, highly sensitive and rapid cardiac phenotyping tool in their seminal paper on in vivo strain analysis.

 

Ronglih Liao, MD, Associate Professor of Medicine, Harvard Medical School said, "We believe that with strain analysis, we now have a very effective and efficient method for non-invasively detecting early cardiac performance irregularities in mice. While recognizing that this method requires special expertise and experience to implement, we are very excited about prospects for applying these analyses in future studies of experimental therapeutics."

The VevoStrain software replaces Tissue Doppler imaging as the assessment tool for quantifying myocardial mechanical function and deformation. Additional features of the software include measurement of cardiac wall motion abnormalities, dyssynchrony (delayed ventricular activation and contraction) and myocardial mechanics.
