CT perfusion in acute stroke.

Khandelwal N - Indian J Radiol Imaging (2008)

Bottom Line: Stroke is a heterogeneous syndrome caused by multiple mechanisms, all of which result in disruption of normal cerebral blood flow and thereby cause cerebral dysfunction.Delay in diagnosis and treatment translates into increase neuronal loss and thereby increased morbidity.This article is an endeavor to explain the pathophysiology of cerebral ischemia and the role of CT perfusion in detecting it.

ABSTRACT
Stroke is a heterogeneous syndrome caused by multiple mechanisms, all of which result in disruption of normal cerebral blood flow and thereby cause cerebral dysfunction. Its early diagnosis is important as its treatment is dependent on the time elapsed since ictus. Delay in diagnosis and treatment translates into increase neuronal loss and thereby increased morbidity. CT scan, and in particular perfusion CT, has helped greatly in the early diagnosis of stroke. This article is an endeavor to explain the pathophysiology of cerebral ischemia and the role of CT perfusion in detecting it.

Figure 0003: Intracerebral vessels (circle of Willis) seen in detail on VR image

Mentions: This is useful in the assessment of stenosis or occlusion of the carotid arteries [Figure 2] or vertebral arteries in the neck, which can act as predisposing factors for a stroke. Also, the evaluation of intracranial arteries [Figure 3] is possible with a high degree of accuracy. CTA is now gradually replacing digital subtraction angiography (DSA) for this purpose. It is however important to stress the need for evaluation of the source or base images along with the reconstructed images as any kind of reconstruction is operator dependent and there is some inherent loss of information in these techniques.
