Blood-brain barrier scans could personalize stroke care using existing MRI data

When a person first exhibits signs of having a stroke, the timing of treatment is critical to restore blood flow to the brain and support recovery. In addition to studying and implementing ways to treat patients faster, investigators have been studying how to make predicting and treating stroke more precise. A new study in the journal Stroke introduces a concept of brain imaging known as blood-brain core imaging, or "leaky core," that could potentially accelerate this progress and transform the way that many strokes are treated.
