We implemented B1+ correction for our metabolite concentration estimation and analyzed the influence of B1+ inhomogeneities. Since the B1+ field is relatively homogeneous in the center of the brain anyways, the biggest effects were observed closer to the fringes of the brain. The concentration estimates increased between 1.0% and 5.6% for different metabolites when comparing B1+ correction to simple T1 correction, remaining within the spectrum of values established by previous literature.
