Abstract

We compared three methods for B1 correction of relaxation-compensated Amide-CEST and Nuclear Overhauser Enhancement (NOE) effects at 7T: (1) a linear model; (2) the eight-point interpolation method; and (3) Bloch-McConnell equations (BE) correction algorithm. In the low B1 regime of 0.10 - 0.50 μT, a simple linear model is sufficient to mitigate B1 inhomogeneity of Amide-CEST and NOE effects at 7T.
