Recent technological developments have improved understanding of not only the structural changes following cerebral arterial occlusion, but have also highlighted the dynamic evolution of stroke pathophysiology. Although altered cerebral tissue metabolism is a central feature of such changes following stroke, direct imaging correlates of metabolic activity are currently not used for therapeutic decision making. However, metabolic imaging may potentially improve targeting of therapies to those patients with a relevant tissue substrate. In this chapter we discuss imaging techniques which may provide metabolic information in acute stroke. Although positron emission tomography is the gold standard technique for metabolic imaging in acute stroke in a research environment, magnetic resonance techniques such as spectroscopy, 17O imaging, and deoxyhaemoglobin weighted imaging may have have potential clinical utility. However, despite measuring relative ­concentrations of metabolites directly, the application of magnetic resonance spectroscopy has been limited by issues surrounding quantification and signal to noise ratio. 17O and deoxyhemoglobin weighted imaging are promising, but require to be validated in acute stroke. In this chapter we discuss potential future directions of these metabolic imaging in translational stroke research.
