Letter From the Editors

This seminar devoted to advances in metabolic brain imaging reveals the remarkable strides that have been made in the past half century concerning our understanding of how the brain functions. As far back as 1948, 131I labeled to the dye, fluorescein, was used as a tumor-localizing agent with external detection with Geiger-Muller detectors and, subsequently, scintillation detectors.1 Regional brain blood flow was measured using scintillation detectors over the scalp after 133Xe administration either by inhalation or intravenous injection in solution.
