in our center we are  evaluating whether to introduce a T2 into a protocol that, among others, already includes a T1 and a FLAIR sequences.

Our main concern is to to maximize the information-to-duration ratio of the entire protocol.

In order to improve the subfields' segmentation we read that it is better to add a T2 or "other" sequences.

Will the FLAIR alone (+T1)  can work well as the T2?

If instead the T2 is preferable, what is the coarsest-but-still-informative resolution you suggest?

Thank you for sharing your experience!

Have a nice day,

Luigi.
