CT Brain Perfusion

Determine areas of reduced cerebral blood flow as compared to the contralateral hemisphere
Generates qualitative and quantitative information about changes in image intensity over time. The application calculates and displays quantitative color maps of cerebral blood flow (CBF), cerebral blood volume (CBV), mean transit time (MTT) and time-to-peak (TTP), and provides summary maps which may help physicians in determining areas of reduced cerebral blood flow compared to the contra lateral hemisphere.

  • Perfusion and summary maps can be generated automatically and sent to PACS for convenient reviewing.
  • With studies of sufficient scan duration, permeability analysis can be used as an assessment of the contrast agent permeation of the blood-brain barrier.
  • The default parameters and thresholds used to create the summary maps may be edited by the user according to the physician’s preference.
  • Automatic motion correction that can be further refined manually if needed.
  • Quality indicators (“traffic lights”) point at possible acquisition faults that may affect the results.
  • Pre-defined ROI templates for systematic and reproducible quantitative regional results.
