title: Dynamic phosphorus-31 spectroscopy after fructose load in experimental biliary liver cirrhosis.
abstract: OBJECTIVE
  The authors investigated the usefulness of dynamic phosphorus-31 magnetic resonance (MR) spectroscopy in the assessment of hepatic function by studying the effect of a fructose load on a rat model of liver cirrhosis.
  
  
  METHODS
  In vivo P-31 MR liver spectra of eight rats with bile duct ligature and 10 control rats were obtained every 4.6 minutes before and after intraperitoneal fructose load (10 mmol per kilogram of body weight).
  
  
  RESULTS
  In the basal spectra of the experimental group, the phosphomonoester peak was higher than in the control group (P = .026). After the fructose load, the phosphomonoester peak increase and the inorganic phosphate peak decrease were significantly less marked in the experimental group (P = .003). There was a linear correlation between the serum level of bilirubin and the phosphomonoester increase (r = .61, P < .001).
  
  
  CONCLUSIONS
  Dynamic P-31 MR spectroscopy may be useful in the assessment of hepatic function in chronic liver disease.
