  • Title: Chronological change of brain abscess in (1)H magnetic resonance spectroscopy.
    Author: Akutsu H, Matsumura A, Isobe T, Anno I, Takano S, Itai Y, Nose T.
    Journal: Neuroradiology; 2002 Jul; 44(7):574-8. PubMed ID: 12136358.
    Abstract:
    We studied chronological magnetic resonance spectral changes in brain abscesses before and after medical and/or surgical treatment. We examined five patients with MRI imaging and (1)H magnetic resonance spectroscopy (MRS) on two or more occasions, using two volume-of-interest patterns, and saw chronological changes related to the evolution of the abscess. A spectrum specific for brain abscess was found in three of the five cases, while two showed a single lactate peak in the first study. In two cases, phenylalanine or alanine appeared in the second study. We observed the disappearance of the specific spectra and a single lactate peak following surgery. Only one patient showed different spectra in different volume of interest.
