Abstract
Neuroinflammation is a dynamic process which undergoes significant changes in spatial distribution and intensity within hours and days after an acute brain injury. At present non-invasive in vivo imaging methods like positron emission tomography (PET) offer the only possibility to capture this dynamics longitudinally in the same subject and the entire brain. Amongst the multitude of cellular and non-cellular mechanisms which constitute the complex neuroinflammatory reaction, microglia and macrophages have been the primary targets for developing non-invasive imaging methods. This chapter is an introduction into the basic principles of microglia imaging with PET, its application to ischaemic stroke and traumatic brain injury in both animal models and clinical imaging in patients. Future developments towards magnetic resonance imaging (MRI) of neuroinflammation and imaging of specific enzyme activity in the neuroinflammatory cascade are discussed.
