Multi-compartment separation in magnetic resonance using transient steady-state free precession imaging

摘要

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 T₂ decay so that it can be more accurately measured.
