Application of the gagCEST mapping technique on human
knee is complicated by technical limitations of
scanners, safety regulations and by an inhomogeneous

field
over the knee cartilage. Measurements on human
volunteers using either Gaussian or adiabatic full
passage hs2 saturation pulses showed unexpected regional
variations in MTR
asym
values
in femoral cartilage. By varying frequency of the
saturation pulses in a range of 60 Hz, increased
intensity and improved homogeneity of the MTR
asym
maps
was achieved.
