Features & Benefits
The Perfusion CT application allows the quantitative evaluation of dynamic CT data of the brain following the injection of a compact bolus of iodinated contrast material. It mainly aids in the early differential diagnosis of acute ischemic stroke. Additionally it allows imaging of blood brain barrier disruption in brain tumors.
By providing images of cerebral blood flow (CBF), cerebral blood volume (CBV) and time-to-peak from one set of dynamic CT images, perfusion CT allows a quick and reliable assessment of the type and extent of cerebral perfusion disturbances. Perfusion CT supports simultaneous multislice processing as well as the stringent time and workflow requirements in an emergency.
The additional capability to generate permeability images of brain tumors may enhance the physicianâs ability to grade tumors, plan biopsies and monitor therapy.
