During offline discussion: We should also add T1 rho since it is part of BIDS. Quick search led me to this paper, https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4700236/, which seems highly relevant for a definition: "T1ρ (or T1ρ) relaxation time describes spin-lattice relaxation in the rotation frame at the presence of an external RF pulse in the transverse plane."
