Fig. 1From: Improving the evaluation of cardiac function in rats at 7T with denoising filters: a comparison studyExample of image filtering on a short axis slice. For each image, the plot displays the signal along the corresponding red line located at the level of the left ventricle. With FLASH sequence, the blood appears in white and the myocardium in grey. a) raw image (no filter), b) anisotropic filter, c) total variation filter and d) ORNLM filterBack to article page
