Journal ArticleDOI
Cerebral glucography with positron tomography. Use in normal subjects and in patients with schizophrenia.
Monte S. Buchsbaum,David H. Ingvar,Robert M. Kessler,Robert N. Waters,J. Cappelletti,Daniel P. van Kammen,A. Catherine King,Jeannette L. Johnson,Ronald G. Manning,Richard W. Flynn,Lee S. Mann,William E. Bunney,Louis Sokoloff +12 more
TL;DR: Local cerebral uptake of deoxyglucose labeled with fluorine 18 was measured by positron-emission tomography in eight patients with schizophrenia and in six age-matched normal volunteers, indicating relatively lower glucose use than normal control subjects.
Journal ArticleDOI
Human brain glucose utilization and cognitive function in relation to age
Ranjan Duara,Cheryl L. Grady,James V. Haxby,D. H. Ingvar,Louis Sokoloff,Richard Margolin,Ronald G. Manning,Neal R. Cutler,Stanley I. Rapoport +8 more
TL;DR: The results indicate that brain oxidative metabolism, when measured under resting conditions with reduced sensory input, is not reduced in relation to age in healthy men and no significant relations between intelligence and resting cerebral metabolism are evident.
Journal ArticleDOI
Cerebral glucose utilization, as measured with positron emission tomography in 21 resting healthy men between the ages of 21 and 83 years.
Ranjan Duara,Richard Margolin,Elizabeth A. Robertson-tchabo,Edythe D. London,Michael Schwartz,J. W. Renfrew,B. J. Koziarz,Magesh Sundaram,Cheryl L. Grady,Angela M. Moore,D. H. Ingvar,Louis Sokoloff,Herbert Weingartner,R. M. Kessler,Ronald G. Manning,Michael A. Channing,Neal R. Cutler,Stanley I. Rapoport +17 more
TL;DR: The results indicate that the cerebral metabolic rate for glucose is not correlated with age in healthy men.
Journal ArticleDOI
[18F]fluorodeoxyglucose positron emission tomography in refractory complex partial seizures.
William H. Theodore,Michael E. Newmark,Susumu Sato,Rodney A. Brooks,Nicholas J. Patronas,Robert de la Paz,Giovanni DiChiro,R. M. Kessler,Richard Margolin,Ronald G. Manning,Michael A. Channing,Roger J. Porter +11 more
TL;DR: Positron emission tomography with simultaneous electroencephalographic monitoring was performed with {18F}fluorodeoxyglucose in 20 patients with complex partial seizures who had normal computed tomographic scans, finding a tendency for patients to have higher overall metabolic rates when taking less medication.
Book ChapterDOI
Regional Correlations in Patterns of Glucose Use in Patients with Schizophrenia and Normal Subjects During Mild Pain Stimulation
R. M. Kessler,C. M. Clark,M. S. Buchsbaum,Henry H. Holcomb,R. A. Margolin,J. Cappeletti,Michael A. Channing,Ronald G. Manning,D. P. van Kammen,Anna C. King,Jeannette L. Johnson +10 more
TL;DR: The development of the 18F-labeled 2-fluorodeoxyglucose (218FDG) method has produced a powerful tool for studying cerebral energy metabolism with positron tomography in resting subjects and schizophrenic subjects at rest and off medication.
