Hello,
While researching effective methods to view strokes I came across studies that suggest that MRIs may lead to false negatives especially for strokes that are located in the posterior portion of the brain. I found this interesting as I believed that MRIs were pretty accurate in terms of diagnosing strokes/ischemias. This brings me to the real topic of this post. At an internship I received a case study of a baseball player whose main side effects were headaches and vision changes. I suspected that a silent stroke (maybe in the occipital lobe) may be the cause of the vision changes but the MRI seemed clear. Is it possible that a stroke in the posterior portion of the brain occurred but it just isn’t showing up on the MRI. What additional steps in the diagnostic process should be used to help rule out the possibility of a false negative (any additional scans etc.) I can link the MRI from the case study below but I don’t want to break the rules so I’m going to wait a bit first.
