[Value of CT perfusion for the diagnosis of early middle cerebral artery stroke].
The need for early diagnosis of stroke at the acute phase has increased with the validation of intravenous thrombolysis therapy. The purpose of this article was to determine the accuracy of CT perfusion for the diagnosis of acute MCA stroke. We have retrospectively compared the results on CT perfusion obtained at acute presentation with follow-up imaging in 30 non consecutive patients admitted for suspected stroke that did not undergo thrombolysis. In our series, the sensitivity of CT perfusion for the diagnosis of MCA infarction was 84%. CT perfusion was poor for the diagnosis of lacunar and strictly cortical infarcts with a sensitivity of 20%. CT perfusion can easily and routinely be performed for the diagnosis of acute stroke, especially in centers where MRI may not be readily available.
