Chemically resolved MRI with field inhomogeneity correction

Magnetic Resonance Imaging (MRI) allows spatially resolved in situ identification of chemical species via their shifts from the proton resonance frequency, which is beneficial in chemical engineering. However, traditional spectroscopic methods are time‐consuming at high spatial resolutions. Recent techniques adapt non‐spectroscopic sequences by incorporating prior knowledge of chemical species spectra to overcome this constraint [1], but they remain sensitive to magnetic field inhomogeneities, particularly in large‐bore systems. This work addresses that limitation by combining field inhomogeneity correction with chemical species reconstruction in a unified method.
