Last year, Italian astronaut Luca Parmitano nearly drowned in his own fluids during a harrowing spacewalk-gone-wrong. Now, NASA has teamed with the Houston Methodist Hospital's research institute to make sure that such a thing never happens again—using a CT scanner.
When you shatter your kneecap, the surgeon may use an implanted scaffold to coax your bones to knit back together properly. But what happens to the scaffold once you're healed? With this new system, the scaffold just melts away.
Medicare outpatient claims for 2008 are showing that thousands of Medicare patients received unnecessary double CT scans that year. The practice not only costs the Medicare program millions of dollars, but exposes patients to potentially dangerous doses of radiation.
In attempt to get better data, a hospital overrode default protocol on a CT scanner over a year ago. Now they've realized that they made a little mistake and have been giving people eight times the acceptable doses of radiation.
