Quantification of the global cardiac function from the tagged images is challenging due to the anatomy obstruction by the taglines and low myocardium-to-blood contrast. In this work, a method is presented for customized tagline removal and improving myocardium-to-blood contrast. The proposed method is applied on images from 12 patients to calculate global cardiac functional parameters and compare them to those from cine images. The results show that the proposed method can be used to accurately estimate ventricular volume and mass, which would allow for reduced scan-time through measuring both regional and global cardiac function parameters from one set of images.
