Database of normal human cerebral blood flow, cerebral blood volume, cerebral oxygen extraction fraction and cerebral metabolic rate of oxygen measured by positron emission tomography with
TLDR
Significant between-centre variation was observed in CBV, OEF and CMRO2 by one-way analysis of variance, however, the overall inter-individual variation in CBF, CBV and OEF was acceptably small and building a database of normal cerebral haemodynamics obtained by the 15O-PET methods may be practicable.
Positron emission tomography using fluorine-18 deoxyglucose in evaluation of coronary artery bypass grafting.
TLDR
Preoperative metabolic imaging using PET appears to be useful for predicting the response to CABG, and improvement in metabolic derangement was associated with improvement in regional function after CABGs.
Noninvasive estimation of FDG input function for quantification of cerebral metabolic rate of glucose: optimization and multicenter evaluation.
TLDR
Noninvasive estimation of CMRGlc is made possible by careful measurement of the net injected dose and BSA, which was significantly smaller than that based on body weight.
Role of the nondominant hemisphere and undamaged area during word repetition in poststroke aphasics. A PET activation study.
TLDR
This study shows the importance in aphasic patients of the mirror regions of the left PIF and PST in the nondominant (right) hemisphere for performing the word repetition task and the importance for nonfluent aphasics of the recruitment of the undamaged PIF for spontaneous speech.
Effect of mastication on regional cerebral blood flow in humans examined by positron-emission tomography with ¹⁵O-labelled water and magnetic resonance imaging.
TLDR
Increases in regional cerebral blood flow in the primary sensorimotor areas, supplementary motor areas and insulae, and in the cerebellum and striatum demonstrate that chewing activates widespread regions of the brain.
Normal uptake of 18F-FDG in the testis: an assessment by PET/CT
TLDR
Some uptake of FDG is observed in the normal testis and declines slightly with age, and Physiological FDG uptake in the testis should not be confused with pathological accumulation.
Difference in vocal tract shape between upright and supine postures: Observations by an open-type MRI scanner

Value and limitation of stress thallium-201 single photon emission computed tomography: comparison with nitrogen-13 ammonia positron tomography.
TLDR
Since stress-delayed SPECT with single tracer injection detected fewer transient defects, it may underestimate the presence of myocardial ischemia, compared with high resolution PET imaging with two tracer injections.
Usefulness of L-[methyl-11C] methionine-positron emission tomography as a biological monitoring tool in the treatment of glioma.
TLDR
The ability of MET-PET to reflect the biological nature of gliomas makes it an excellent method for monitoring active tumor tissue, and treatments based on its findings should provide a powerful clinical protocol in the course ofglioma therapy.
Annular Geometry in Patients With Chronic Ischemic Mitral Regurgitation: Three-Dimensional Magnetic Resonance Imaging Study
TLDR
Patients with CIMR had greater septal-lateral and commissure-commissure mitral annular dimension, larger intertrigonal distance, and flattened saddle shape of mitral Annulus, which may be important in the pathogenesis of chronic ischemic mitral regurgitation.
