Imaging the Human Brain with Functional CT Imaging
Abstract
Recent advances in multi-detector computed tomography (CT) have revitalized its role in the clinical routine. In the field of cerebral perfusion, CT provides a rapid, low-cost functional imaging, which by the utilization of a suitable tracer kinetic analysis can provide valuable information in many clinical applications, like acute stroke, cerebrovascular reserve capacity, vasospasm after subarachnoidal hemorrhage, cerebral trauma, tumor imaging, and brain death diagnosis. The limitations of the existing commercially available post processing software are discussed and a new distributed-parameter tracer kinetic model for generating more accurate perfusion parametric maps is introduced.
