Deciphering the fibre-orientation independent component of R2* (R2,iso*) in the human brain with a single multi-echo gradient-recalled-echo measurement under varying microstructural conditions

Francisco J. Fritz, Laurin Mordhorst, Mohammad Ashtarayeh, Joāo S. Periquito, Andreas Pohlmann, Markus Morawski, Carsten Jaeger, Thoralf Niendorf, Kerrin Pine, Martina F. Callaghan, Nikolaus Weiskopf, Siawoosh Mohammadi

This paper introduces a method to estimate the orientation-independent R2* (R2,iso*) from multi-echo MRI data, showing it works best with long echo times but fails with typical in-vivo protocols.
