Đột quỵ thiếu máu não (CT perfusion) | Trường hợp Hình ảnh

Initial non-contrast CT revealed focal hyperattenuation within the right M1 segment, suggestive of an acute thrombus. There was no evidence of intracranial hemorrhage. An early, subtle hypoattenuation was noted in the right lentiform nucleus, indicating a developing ischemic lesion.

CT angiography confirmed an occlusion of the right M1 segment. The remainder of the intracranial and extracranial circulation was normal, including no internal carotid artery disease.

CT perfusion analysis (RAPID) demonstrated a significant ischemic core and a large surrounding penumbra in the right hemisphere. The perfusion study was of good quality, without motion artifacts in the rotation and translation graphs. Additionally, the venous peak was appropriately higher and later than the arterial peak. There are no sign also of truncation artifact.
