Combined Use of F-18 Fluorocholine Positron Emission Tomography and Magnetic Resonance Spectroscopy for Brain Tumor Evaluation

Choline metabolism is often abnormal in malignant brain tumors.Brain positron emission tomography (PET) imaging with F-18 fluorocholine (FCH) was performed on 2 patients with intracranial lesions suspected to be high-grade malignant gliomas on the basis of magnetic resonance (MR) imaging and multivoxel 1H-MR spectroscopic imaging (MRSI) findings. Standardized uptake value (SUV) measurements on PET were compared with measurements of...
