Evaluation of the Value of Cerebral Perfusion Scintigraphy in the Study of Post-stroke Fatigability

Overview

At present there is no consensus for post-stroke imaging except for the realization of early cerebral CT at 24 hours post-thrombolysis. The use of cerebral perfusion scintigraphy would predict the course of a stroke. Indeed, it has been shown that a good perfusion is linked to a good evolution of the neurological deficit. This test is used routinely to evaluate cerebral perfusion in patients with stroke. This technique was also used to study the mechanisms of post-stroke aphasia and to highlight neuronal disconnections after stroke, a reflection of the functioning of neural networks. Neuropsychological tests are almost always done at 3 months. Fatigue is studied: PSF scale at 3 months, 6 months and 2 years. Research needs to be continued in this area because the pathophysiology remains unknown and the symptoms are disabling for patients. Using cerebral perfusion imaging would bring elements of understanding of this mechanism and ultimately improve the management of patients.
