Hello again, this is Frank Gaillard from radiopaedia.org. And today we're going to be discussing imaging of acute ischemic stroke. In most instances, cerebral ischemia results from a thromboembolism, either from the heart or from the carotid. Rarely it is also due from paradoxical emboli through the patent foramen ovale, or from aorta atherosclerotic disease. This is seen most commonly in the setting of either angiography or cardiac surgery. In situ thrombosis within the cerebral circulation is seen either superimposed on pre-existing arteriosclerotic disease,or in the setting of arterial dissection.

【Stroke-acute Infarction（part 1）急性缺血性/梗死性脑卒中】
大家好，我是来自放射组织的Frank Gaillard。我们今天要讨论的内容是急性缺血性脑卒中的影像表现。在大多数病例中，脑缺血是由于血栓栓塞导致的，栓子来源于心脏或者颈动脉。少数栓子来源于未闭的卵圆孔，而造成反常性栓塞，或来源于主动脉粥样硬化的斑块。在血管造影或者心脏手术时可以发现这些栓子。大脑血液循环中的原发性栓子常见于多次复发的动脉硬化，或主动脉夹层。
