OBJECTIVE: To investigate the metabolic changes, pathological state and histological types of intracranial tumors with hydrogen-1 magnetic resonance spectroscopy (H-1 MRS). METHODS: Thirteen patients with intracranial tumors were studied with localized proton magnetic resonance spectroscopy (H-1MRS), in vivo. All spectra were obtained with a 2.0 T whole body MR imaging system. RESULTS: All the spectra of these tumors exhibited high ratios of choline (Cho)/creatine (Cr) and Cho/N-acetyl aspartate (NAA), and histologically different tumors showed obvious variations in the metabolite ratios. Significant differences of Cho/Cr ratio were found between meningiomas and astrocytomas by statistical evaluation. The spectra obtained after operation were remarkably different from those before operation. CONCLUSION: H-1 MRS can serve as a non-invasive clinical test for therapeutic and prognostic uses for intracranial tumors.
