Perfusion Analysis is the dedicated software which analyzes cerebral blood flow from contrast-enhanced cerebral CT images.
A perfusion image allows grasping blood-flow abnormalities such as brain infarction, stenosis and occlusion of the main artery in their early stages compared to a plain CT image. Particularly, the perfusion study is expected to make the diagnosis of lesions caused by acute brain infarction promptly.
In addition, an effective postoperative follow-up can be expected.
Examinations are made by carrying out dynamic scans of specified head sections while applying a bolus injection of an iodized contrast medium. By analyzing the time-density curve of the scanned images, information on the dynamic cerebral blood flow such as Cerebral Blood Flow (CBF), Cerebral Blood Volume (CBV) and Mean Transit Time (MTT) can be acquired.
