In this medical video learn how doctors are using a similar version of a Doppler radar that tracks storms to look at blood flow in the brain and help prevent stroke.

Jennifer Matthews: Airplanes are his hobby. But Wade Hilmo's been grounded from flying real ones since January. Wade Hilmo: I could feel kind of a tingling start at the back of my neck, and it came forward over the top of my head and then as soon as it came over the top of my head I got really dizzy. Jennifer Matthews: A ruptured aneurysm was bleeding in Wade's brain. Wade Hilmo: One of the things that strikes me is if I had been living 50 years ago, or 100 years ago, this probably would have been fatal. Jennifer Matthews: But today's technology may have saved his life. After surgery, doctors used transcranial doppler to see if Wade was at risk of having a stroke -- a common result of a ruptured aneurysm. Dr. David Newell: Every day or twice a day we can go in and check the vessels with the ultrasound to see if they were going into spasm, which is the prelude to a possible stroke in these patients. Jennifer Matthews: It's a slight variation of the same doppler technology meteorologists use to watch a storm develop as it happens. It uses ultrasound to measure blood flow in the brain in real time. The technology can also be used to help treat migraines, and unlike other methods, it's non-invasive. Dr. David Newell: It's based on the same Doppler principal where sound waves are sent toward an object and then received waves that are reflected off that object are received by the equipment. Jennifer Matthews: For Wade, it meant peace of mind during a scary time. Wade Hilmo: I knew that it was a very serious thing. Jennifer Matthews: He's back on his feet now -- fully recovered -- and hopes to soon be back in the air. This is Jennifer Matthews reporting.
