...Tuesday night in late September and the city is talking sports. September is always a time of controversy in this city, and this September is no exception. From a quick scan of the radio talk shows it is easy to find the controversy and the arguments that nourish and fortify sports, raising it from the level of a pastime to a zeal, a religion...
...example glucose, which is the brain's main source of energy, tagged with a telltale radioactive substance that emits positively charged particles. These positrons, when they combine with negatively charged electrons normally found in the body's cells, emit gamma rays that can be detected by a scanning device. Collected and translated into color-coded images, the resulting patterns indicate the intensity of metabolic activity. Because the radioactive substances are so short-lived, anyone undergoing a PET scan is exposed to very little radiation...
Still, the most dramatic impact of PET scanning so far has been in studies of the brain. The technique is painlessly providing detailed information about how a normal brain reacts biochemically to such stimuli as the eyes seeing light, the ears hearing a story and even the movement of an arm or a leg. For example, when a subject moves his right hand, the PET scan indicates increased glucose use by the region of the left side of the brain controlling the action. Physicians have begun to use PET scanning in determining therapy for people who have had strokes...
...storing the information on tape. Not until Voyager 2 emerged from behind Saturn and again began radioing back data did scientists learn that something had gone wrong. As Voyager 2 crossed the rings, the playback showed, the cameras began missing their targets. Somehow the spacecraft's movable "scan platform," which acts as an aiming mechanism for the narrow-and wide-angle cameras as well as several other optical instruments, had slowed, then stuck. The platform could swing up and down but not sideways, leaving Voyager 2's cameras looking out into the dark void of space...
Vadala turned the information she had collected over to attorneys, who filed a malpractice suit against Neurologists Wayne Tobin and Michael Aptman. The suit contended that Becky had shown signs of a pressure buildup and a scan was ordered only after she arrested...
