Advanced MR techniques: diffusion MR imaging, perfusion MR imaging, and spectroscopy

Neuroimaging Clin N Am. 1999 Aug;9(3):439-53.

Abstract

Recent technical advances in MR imaging have enabled the authors to investigate early physiological changes in acute ischemic stroke lesion. Diffusion and perfusion MR imaging can provide clinically useful information not only for early detection of ischemia, but also for prediction of tissue outcome. MR spectroscopy is a potentially powerful tool to study acute stroke, but its clinical value has been limited due to long examination time and low spatial resolution.
