A comparative PET study of [18F]2-fluoro-2-deoxy-D-glucose (FDG) and [18F]2-fluoro-2-deoxy-D-mannose (FDM) uptake was performed in 13 patients with focal brain lesions. Differences between FDG and FDM with respect to model rate constants, lumped constant, and estimated metabolic rate for glucose were determined on a regional basis. Across whole brain, the transport rate constant K1* was almost unchanged, whereas k2*, describing the transport back from tissue to plasma, was 6% higher, and the phosphorylation rate constant k3* was 9% lower for FDM compared to FDG. This implies a 20% lower lumped constant for FDM. No significant regional variability of this differential tracer behavior was observed in normal or in lesioned brain tissue. Thus, results from previous FDG studies, where the radiotracer was not 100% pure FDG but contained varying amounts of FDM, can easily be corrected by adjustment of the lumped constant employed in metabolic quantitation.

D001921 Brain The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM. Encephalon

D001932 Brain Neoplasms Neoplasms of the intracranial components of the central nervous system, including the cerebral hemispheres, basal ganglia, hypothalamus, thalamus, brain stem, and cerebellum. Brain neoplasms are subdivided into primary (originating from brain tissue) and secondary (i.e., metastatic) forms. Primary neoplasms are subdivided into benign and malignant forms. In general, brain tumors may also be classified by age of onset, histologic type, or presenting location in the brain.
