ABSTRACT:
Disclosed is a method of quantitatively separating tissue signals based on relaxation time differences. The method uses the transient signal decay in steady-state free precession (balanced SSFP) imaging to provide an alternative to standard CPMG methods of T2-relaxometry. The balanced SSFP technique allows 3-4 times the temporal resolution of CPMG, and also slows the short T2decay so that it can be more accurately measured.
