Abstract:Objective To investigate the test methods for Siemens Skyra 3.0 T MRI magnetic field homogeneity. Methods The spectral
peak option and bandwidth-difference option were used to test the 3.0 T MRI magnetic field homogeneity. Results The full width at half
maximum (FWHM) of MRS phantom was 0.027 ppm, and the inhomogeneity of coronal, sagittal and axial detected by bandwidth-difference
option were 0.49, 0.98 and 0.91 ppm, respectively. Conclusion The MRI magnetic field homogeneity is favorable, and meets the standard.
