Hepatic encephalopathy (HE) is a serious neuro-psychiatric complication of liver disease. To elucidate the pathogenesis of HE, 31P-MRS has been used. However, previous findings remain controversial due, at least in part, to relatively low sensitivity of the nucleus and limited spectral dispersion at low field. To this end, we have characterized HE in animal using 31P-MRS with substantially improved spectral dispersion and SNR at 9.4 T. Our results demonstrate that 31P-MRS at high field allows for highly resolved spectra in vivo, and thus can provide more vivid picture of the altered brain metabolism in the progression of HE.
