We proposed a new method that separates susceptibility-induced frequency shift from chemical shift/exchange-induced frequency shift in a phantom using three axes scanned datasets. The method was successfully validated in numerical simulation and phantoms and reported susceptibility and chemical shift/exchange in vegetable oil (susceptibility: 0.66±0.02 ppm; chemical shift: 3.58±0.01 ppm) and iron oxide (concentration: 0.025%; susceptibility: 0.30±0.02 ppm; chemical exchange: 0.039±0.003 ppm).
