Abstract:
The prognosis and outcome in patients with intracerebral hemorrhage are closely correlated with perihernatoma tissue injury and recovery.The pathophysiological mechanisms after intracerebral hemorrhage are extremely complicated.There are regional blood flow changes in perihematoma tissues,but whether there is a similar“penumbra”as in cerebral ischemia remains uncertain.At present,studies in this field have mainly focused on the imaging detection of regional cerebral blood flow and metabolism.The study methods frequently used include single photon emission computed tomography,functional magnetic resonance imaging,magnetic resonance spectroscopy,positron emission tomography and CT perfusion imaging,etc.The application of these imaging techniques have provided some valuable methods for identifying whether perihematoma penumbra is present or not,but further studies are needed to confirm it.
