¥ Very little difference between
OLSQ and REML,
even at so low a threshold
¥ Data
is markedly less correlated
in time (UNM Siemens
1.5 T), as shown by
maps of REML-estimated
r1
¥ Similar data from U Iowa GE
1.5 T has similarly low temporal
correlation
¥ BWH & MGH 3 T data has higher
temporal correlation than
FBIRN 1.5 T, but lower than
NIH 3 T —— ???
