Ultra-acute CT perfusion imaging

Описание: A stroke patient with a mild right hemiparesis (NIH Stroke Scale score 4) underwent dual-slab CT perfusion (CTP). In the midst of acquiring the lower CTP slab, she became aphasic and developed a dense right hemiparesis (NIH Stroke Scale score 17). Reconstruction of the CTP into a dynamic CT angiogram demonstrates fragmentation of an internal carotid artery thrombus at the time of clinical worsening (figure 1; video on the Neurology® Web site at Neurology.org). The upper CTP slab, acquired 2 minutes later, provides the earliest known view of the hemodynamics of ischemic stroke in humans. It demonstrates total absence of flow to the middle cerebral artery territory during the ultra-acute phase (figure 2). Follow-up imaging demonstrates infarction of this territory.
