Measurement reproducibility of slice-interleaved T1 and T2 mapping sequences over 20 months: A single center study
Fig 5
Reproducibility between sessions, and repeatability between repetitions and slices of slice-interleaved T2 mapping sequences were estimated using coefficients of variation (CV).
Slice-interleaved T2 mapping had good between-session reproducibility (CV: SE T2 = 2.5%, slice-interleaved T2 2P = 3.5%, slice-interleaved T2 3P = 6.3%, slice-interleaved T2 4-T2preps 2P = 4.7%, slice-interleaved T2 4-T2preps 3P = 6.7%), between-repetition repeatability (CV: slice-interleaved T2 2P = 2.7±0.2%, slice-interleaved T2 3P was 6.0±0.2%, slice-interleaved T2 T2preps 2P = 4.2±0.2%, slice-interleaved T2 T2preps 3P was 6.5±0.2%), and good between-slice repeatability (CV: slice-interleaved T2 2P = 2.9±0.2%, slice-interleaved T2 3P = 6.5±0.3%, slice-interleaved T2 T2preps 2P = 4.5±0.4%, slice-interleaved T2 T2preps 3P was 7.0±0.4%).
