In ultrasonic tissue characterization the small reflections originating from the scattering structures inside the tissue are analyzed. To obtain diagnostic performance for tissue characterization by means of analysis of echocardiographic images we use methods of mathematical texture analysis. We investigate whether myocardial changes effect the texture of ultrasonic images and if this could be described using quantitative texture analysis. The texture analysis was computed in a single window of an ultrasound image/sequence covering the inner myocardial septum. Parameters from gray level histogram, co-occurrence matrices, run length statistics and run difference, from power spectrum and fractal dimensions were investigated to provide satisfying and generalizable results for classification of the myocardium. A set of parameters that could discriminate between normal and pathological myocardium were extracted. The results of 142 biopsies were compared with those of texture analysis in echocardiograms of 106 patients suspected having myocarditis. Using the reduced set of parameters the best sensitivity was 89.0% and the specificity was 83.6%. Myocarditis is associated with echocardiographic texture alteration. Texture analysis with methods of digital image processing can reliably identify myocarditis. A suitable solution for a computer-assisted non- invasive support for the diagnosis and detection of myocarditis was found.
