Lateralized abnormality of high-energy phosphate and bilateral reduction of phosphomonoester measured by phosphorus-31 magnetic resonance spectroscopy of the frontal lobes in schizophrenia.
Magnetic resonance spectroscopy (one-dimensional chemical shift imaging) was used to measure membrane phospholipid metabolism and high-energy phosphate metabolism in the left and right frontal lobes of 27 schizophrenic patients. In the schizophrenic patients, the phosphomonoester peak area was decreased in bilateral frontal lobes compared with that in age-matched normal subjects. On the other hand, the peak area of beta-adenosine triphosphate was increased in the left frontal lobe in the schizophrenic group. The phosphocreatine peak area was increased in the left frontal lobe of schizophrenic patients with high scores on the Scale for the Assessment of Negative Symptoms (SANS).
