Measuring myocardial motion and strain using tagged magnetic resonance imaging provides valuable diagnostic indicators of heart disease. For over a decade, the clinical adoption of magnetic resonance (MR) tagging was limited due to the lengthy image acquisitions involved, multiple long patient breath-holds, and manually intensive postprocessing. The implementations of the harmonic phase (HARP) magnetic resonance imaging (MRI) methodology provided fast and efficient postprocessing tools for tagged images. This chapter presents a review of HARP-tagged MRI analysis and a brief survey of related MR pulse sequences that exploit HARP concepts to provide accelerated imaging, volumetric imaging, and improved quantification of myocardial motion and strain from tagged MR images.
