Radiation Dose Reduction in Perfusion CT Imaging of the Brain: a Review of Existing Approaches
Introduction
For the evaluation of hemodynamic changes in various tissue types, perfusion CT (PCT) is a valuable imaging technique.
A common field of clinical application is acute stroke imaging: PCT of the brain allows a highly accurate detection of ischemic lesions as well as being able to distinguish infarct core and penumbra brain tissue, thus providing a basis for clinical decisions, for instance regarding recanalization therapy.
