Answer from Ted Lowenkopf, M.D. , medical director of Providence Stroke Center: Yes, you can have a stroke and not know it. A stroke's effects can be undetectable if the stroke is small or if the tissue damaged does not serve a critical function. Evidence of the stroke would show on a CT scan or an MRI of the brain, but it might not produce symptoms. But you really may be asking if a stroke can occur without your realizing, at the time, that it's happening â such as when you are asleep or when the effects are minor. Letâs look at those two scenarios separately.
An MRI scan can be used as an extremely accurate method of disease detection throughout the body and is most often used after the other testing fails to provide sufficient information to confirm a patient's diagnosis.In the head, trauma to the brain can be seen as bleeding or swelling.n MRI scan can evaluate the structure of the heart and aorta, where it can detect aneurysms or tears. MRI scans are not the first line of imaging test for these issues or in cases of trauma.
