Although many methods already exist to map T1, T2 and M0, these often involve special sequences not readily available on clinical scanners and/or may require long scan times. In contrast, the proposed method can run on most scanners, it offers flexible tradeoffs between scan time and image quality, and it generates spatially-aligned parameter maps. Validation was performed in gel phantoms with varying concentrations of contrast agents, and in vivo examples are presented from three neuroradiology patients. Compared to other quantitative mapping methods, the present method is meant to stand out in terms of its practicality and availability.
