CT Perfusion in the Management of Acute Stroke

Dynamic CT perfusion imaging of acute stroke.

BACKGROUND AND PURPOSE Because cerebral perfusion imaging for acute stroke is unavailable in most hospitals, we investigated the feasibility of a method of perfusion scanning that can be performed rapidly during standard cranial CT. Our aim was to identify the scanning parameters best suited to indicate tissue at risk and to measure a perfusion limit to predict infarction. METHODS Seventy pat...

Acute stroke imaging: CT with CT angiography and CT perfusion before management decisions.

CT perfusion imaging in the early diagnosis of acute stroke.

Early diagnosis of acute cerebral infarction is critical due to the time limit of thrombolytic treatment. Cerebral computed tomography (CT) perfusion imaging is a new technique, which appears to provide early diagnosis of major vessel occlusions in the brain. CT perfusion imaging also provides valuable information about the hemodynamic status of ischemic brain tissue. In this report, we present...

Behind the Technology: CT Perfusion in the Setting of Acute Stroke Management

[The contribution of perfusion CT in stroke].

Multisection computed tomography (MSCT) was introduced in 1998 and improved neuroimaging quality, in particular concerning acute stroke. Previously, non-enhanced CT was used not only to detect early stroke signs, but also to exclude hemorrhage and non-vascular pathology responsible for the acute neurological deficit. Nowadays, using Perfusion CT (PCT) it is possible to obtain a functional study...
