Definition A tecnique of imaging local metabolic and physiological functions of the brain that is used to construct tomographic representations of functional brain areas.
A technique of imaging local metabolic and physiological functions of the brain that is used to construct tomographic representations of functional brain areas. Positron emission tomography may be used clinically to measure metabolic or physiologic function/dysfunction in specialized applications; for example, a hypometabolic is often associated with the seizure focus in epilepsy patients. As for language, it is a valuable research tool for investigationg functional changes associated with cognitive activation task.

Context The question of whether mental practice has any relevance to physiotherapy has not, to our present knowledge, been addressed experimentally. This might be due to the difficulty of evaluating the effectiveness of mental practice in groups of patients. Measurement of brain metabolism (e.g. using positron emission tomography) could be of interest for selecting those patients who show increased activity in the relevant brain areas.
