چکیده
valine, leucine, or isoleucine, have never been reported in the in vivo proton MR spectra from human brain tumors (2). The apparent weakness of the technique is the ubiquity of lactate, by virtue of its production during glycolysis, and the lack of correlation between measurable lactate levels and histologic grading of cystic tumors. More specific biochemical profiles are possible, though, with the use of in vivo spectroscopic imaging methods. These permit more efficient sampling of both the cystic/necrotic and solid components of intracranial masses, resulting in additional resonance lines (N-acetylaspartate, creatine/phosphocreatine, choline-containing compounds, myo-inositol, and others) that aid in characterization and can be displayed as color maps of metabolite distribution. Also, powerful in vitro methods such as two-dimensional shift correlation (COSY) spectroscopy have yet to be applied to the analysis of fluid or tissue samples in the interventional MR setting. The clinical testing and development of these newer approaches are the challenges radiologists must meet if this initial success at lesion characterization is to be extended and accepted as part of the evaluation of intracranial masses, particularly the ring-enhancing lesion.
