Off-resonance preparatory RF pulse for MR imaging

摘要

The present invention includes a method for MR imaging of a biological matter having H₂O¹⁷ content by performing T1_rho^off imaging of said H₂O¹⁷ content in said biological matter. The T1_rho^off imaging is performed by applying an RF pulse with a resonance frequency offset to said biological matter to create off resonance spin locking conditions in said biological matter. Thus, parts of the biological matter having different H₂O¹⁷ concentrations are differentiated because of their different T2/T1 ratios.
