- Title
Amide proton transfer imaging with improved robustness to magnetic field inhomogeneity and magnetization transfer asymmetry using saturation with frequency alternating RF irradiation.

- Abstract
Amide proton transfer (APT) imaging results in a representative human volunteer. a: B0 map calculated from the low SNR z-spectrum images by the B0 correction algorithm. b: MTRasym map and c: MTRSAFARI map calculated from the high SNR APT images without B0 correction. The uncorrected MTRasym map shows large spatial intensity variation over the brain, which corresponds to the water frequency shift map. The uncorrected MTRSAFARI map shows a remarkable improvement in homogeneity over the brain. From the article by Scheidegger et al (pp 1275-1285).
