Assessment of local contractility of the left ventricle complements global functional parameters such as cardiac output and ejection fraction. The local contraction of the LV is quantifiable by its circumferential strain. We have shown that radial tagging facilitates the extraction of this parameter directly from the k-Space data if the density of the radial taglines is sufficiently high . In this study, we present our initial findings on the performance of this approach and validity of the results.
