Аннотация: 23Na MRI provides additional biochemical information to 1H MRI in terms of cellintegrity and tissue viability. We aimed at determining the sensitivity of 23Na MRS,MRI and MR relaxometry methods available on 7T MR scanner Bruker Biospec70/30 USR and developing of an optimal MRI protocol for small animal 23Na in vivovisualization. The outcomes include 23Na MR spectra, 23Na MR images with SNRs,and T1 and T2 values of 23Na. It is shown that single-pulse 23Na MR spectroscopy candiscriminate different 23Na concentrations, and 3D FLASH pulse sequence adapted for23Na data acquisition may provide the acceptable quality images.
