CT Perfusion 4 : Body Package

CT Application Option: CT Perfusion 4 : Body Package

CT Perfusion allows the user to process dynamic image data and generate functional perfusion parameters based on changes in image absorption over time during the injection of a contrast bolus. The functional maps are calculated in absolute values, so that an intra-patient or inter-patient comparison between different hospitals is achievable.

In addition to the established use of GE Healthcare’s CT Perfusion in the emergency setting for assessment of stroke patients, it has also been used in other applications where absolute quantification of the perfusion parameters is essential.

CT Perfusion

Overall benefits

  • Non-invasive diagnosis of organ perfusion
  • Arterial inflow and venous outflow analysis for the parametric image
  • Easy evaluation through color functional maps of the cerebral and oncologic hemodynamic parameters
  • Tracking drug therapy for hyper vascular tumors
  • Low dose-scan parameters

Clinical Cases

The following cases demonstrate the role Functional imaging has in the assessment of abdominal disease. By providing a biomarker of tumour angiogenesis, CT perfusion is useful in assessing tumour activity.It also provides quantitative measurement for stroke assessment..
