This Strain Rate Imaging (SRI) cineloop of a normal left ventricle was obtained in real-time using a GE Vingmed System FiVe with prototype software and a 2.5 MHz phased array probe. SRI measures the rate of deformation in tissue using a method based on the Doppler technique. In cardiac imaging SRI can, unlike tissue Doppler, clearly differentiate between deforming and stiff muscle segments regardless of overall motion. The method gives insight to cardiac muscle mechanics, and has the potential to improve quantitative stress echo.
