Medical procedures, for instance, rack up massive energy tabs - especially surgeries, emergency services and pathology laboratory tests. "Enormous amounts of energy are required to build and run high-tech systems in common use - MRIs, CT scans, etc. - with many running 24 hours a day," says Pamela Gray, a trustee of the Transition Network, a U.K.-based organization that supports community-level initiatives to improve sustainability and combat climate change. Further, nearly all pharmaceuticals are made from petroleum derivatives, and so are medical materials (think rubber gloves and intravenous tubing). And then there's transportation: transferring equipment, supplies and lab samples...
...life takes them on different paths, he hopes to tease apart the influences of nature and nurture. Ultimately, he hopes to find, for instance, that Anthony Mann's plan to become a pilot and Brandon's to study law will lead to brain differences that are detectable on future MRIs. The brain, more than any other organ, is where experience becomes flesh...
...anything cardiovascular or cerebrovascular." That means that tests of the electrical activity of Kennedy's heart will be useful in isolating any potential abnormalities in his heart function, such as a slow heart rate or an irregular heartbeat, that could have contributed to the seizure. CAT scans and MRIs of the brain will also be needed to ensure that Kennedy's episode wasn't caused by a tumor or infection in the brain...
...Then there were the MRIs of his lumbar spine: Here the docs-in-the-box might have been simply playing the odds. Patients who complain of leg pains often turn out to have what we call radiculopathy, which affects the spinal nerve roots. Sciatica is a well-known term for one type of this. Although caused by pressure on a nerve in the back, there might be very little or no back pain. Patients sometimes just cannot believe there is nothing wrong in their leg. Tim could have been vague about his story, or he might have been so wound...
...today were often on the dangerous fringe list 20 years ago. Aggressive advancement is the hallmark of American medicine. Yet there is, somewhere, a line to be drawn. Why? New diagnostic tests often give us more information than we can actually use or even interpret. If you do enough MRIs or blood tests, for example, you're bound to find something that's off - and that means getting still more tests. New treatments directed against minor problems, or yielding minor improvements, can be major new expenses. Wrist arthroscopy, a high-tech newcomer to my field, seems to treat problems...
