New Super-Sensitive MRI Gives Clearer Picture of Stroke in Action
Gottfried Schlaug, MD, a staff neurologist at Beth Israel Hospital and instructor at Harvard Medical School, says DWI can also be used in conjunction with traditional MRI to estimate how much brain tissue can be salvaged.
He says he analyzed scans from 34 patients who had a stroke and found that by superimposing two MRIs and a DWI, one on top of another, "we can see how a stroke has enlarged. The mismatched area between the two initial MRIs and the last scan, the DWI, shows the area of tissue that may be salvaged." He says it may someday be possible to "tailor treatment for individual stroke patients using this technique."
