Localization Errors in MR Spectroscopic Imaging due to the Drift of the Main Magnetic Field and their Correction
PURPOSE: To analyze the effect of B(0) field drift on multi voxel MR spectroscopic imaging and to propose an approach for its correction. THEORY AND METHODS: It is shown, both theoretically and in a phantom, that for ~30 minute acquisitions a linear B(0) drift (~0.1 ppm/hour) will cause localization...
