In MRI, chemical shift depends on field strength and receiver bandwidth, producing distortion andartifacts. Centered on 3.0 T, we compared abdomen, kidney, lumbar spine, bladder, and a water–canola oil phantomusing literature review and experiments across 1.5/3.0/7.0 T and 4-62.5 kHz (109-217 Hz/pixel) bandwidths. Artifactswere more conspicuous at 3.0 T than 1.5 T, while 7.0 T suffered from signal loss and susceptibility. Lower bandwidthsincreased artifacts, mirrored by phantom results, offering guidance for parameter optimization in high-field MRI.
