hmm.. what is yr CT for? a CT scan?

i didnt really understand the question. was it,

u wanna know the difference between a stroke and a transient ischemic attack? and that if there was a difference between the CT scans of both a stroke and TIA?

well TIA is a mini-stroke that resolves on its own hence transient. a stroke is a stroke which causes pathological consequences.
The risk of a stroke increases dramatically in the days and weeks after a transient ischemic attack, and the TIA may offer an opportunity to find a cause and prevent the permanent neurologic damage that results because of a stroke. also TIA resolves within 24 hrs if im not mistaken.
Within minutes, brain cells begin to die. There are two kinds of stroke. The more common kind, called ischemic stroke, is caused by a blood clot that blocks or plugs a blood vessel in the brain. The other kind, called hemorrhagic stroke, is caused by a blood vessel that breaks and bleeds into the brain.
so basically TIA are mini strokes that have blockages of vessels temporarily. but if they disappear within 24hrs then i dont think u can see it on the CT scan.. hmm actually im not sure about the CT scan part. anyone else?

yes. when i was doing my attachment I was taught to differentiate the CT scans:

CT with hemorrhagic stroke will show a whitish lesion in the brain (because the blood clot is > dense than the brain tissue)

CT with ischemic or infarct will show hypodense area due to hypoxia in the particular infarct area. so CT with TIA and inchemic stroke will be same initially. but the main difference is TIA will resolve within 24 hrs because blood will continue to flow again and from being hypoxic, the area will again have blood supply.
