"T2 mapping has been conducted with T2 turbo spin multi-echo (T2-TSE) 2,5, T2 prepared steady-state free precession (T2p-SSFP) 2,5,8,9, as well as T2 gradient spin echo mapping sequences (T2-GraSE) 10,11. No matter which acquisition technique is used a series of co-registered images is acquired with different T2 echo times 1-4,6-9."

"Normal values of T2 times differ depending on magnetic field strength (1,5 and 3 Tesla), and acquisition sequence (T2-SSFP, GraSE). Because of variations between scanners, the primary use of a local reference range is recommended 1,4 and if a local reference range is not available quantitative results should not be clinically reported 1,4."
"T2 values can then be computed pixel-wise from a signal intensity versus echo time curve fitting model 1-3,12. The variation of other weight factors, e.g. T1 off-resonance, needs to be corrected if not negligibly small, and displacement between the images of the series should be avoided to get accurate values 1,12."
