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 0004: CTP data acquisition is done at the level of basal ganglia

Mentions: Present-day multislice CTs do not allow for whole-brain perfusion assessment. Thus, if an anterior circulation infarct is suspected, data acquisition is done at the basal ganglia level [Figure 4] and if a posterior circulation infarct is likely, then at it is done at the level of the mid-cerebellum. Depending upon the type of scanner, one can take 1–4 sections of 5–10 mm thickness at the levels mentioned. The protocol used in our department is given in Table 3.
