RATIONALE AND OBJECTIVES.: The authors determined whether blood presaturation of
tagged magnetic resonance (MR) images affects identification of left ventricular endocardial
borders. MATERIALS AND METHODS.: Three healthy volunteers underwent MR imaging
performed with a breath-hold segmented spoiled gradient-recalled-echo sequence with
tissue tagging. Two saturation pulses (in the basal and apical regions) were used to
generate black-blood images. Manual segmentation of endocardial contours on black-blood …
