MRI without wanting one Sunday afternoon, Joe e4 Silvers of Tulsa, Oklahoma, fell into a convulsion at his parents' home. "I don't even remember it happening," said Joe (bottom right), who ST. FRANCIS HOSPIT.41 .eTtZLy works in the garage of the Tulsa police department. A CT scan of Joe's brain showed what looked like a stroke. "'But that didn't make sense at all," said Dr. David Fell, "especially in a healthy young man like Joe with no other neurological problems." The answer came in an MRI scan (top right) that showed a tumor (tinted yellow) surrounded by fluid-filled ventricles (green). Dr. Fell removed the tumor and Joe has had no further trouble Six-year-old Nathan Tower, wearing a supportive halo cast (above left), is alive today because of MRI scanning. When doctors in Reno, Nevada, diagnosed a brain-stem tumor, "they told 51 us there was, little hope," said his mother, Margaret Anne. But an MRI scan (left) convinced Dr. Harold L. Rekate of Phoenix, Arizona; that the tumor (shaded red) could be removed. "The MRI . erased the bones around the spinal cord and showed the tumor clearly," said Dr. Rekate, who performed the operation.. "Before MRI almost no one would have attempted it."
