...that contribute to vast waste, reformers say. In a study released in August, Florida officials reported that doctors owned 93% of the diagnostic-imaging centers surveyed, 78% of the radiation-therapy centers, 60% of the clinical labs and 38% of the physical- therapy and rehabilitation centers. Miami doctors prescribe MRI scans (cost: $800) and various lab tests about twice as often as doctors in Baltimore, where very few own the equipment. Lab charges are more than twice as high at facilities owned by doctors...
...tests, which uses Magnetic Resonance Imaging (MRI) techniques, helps give doctors an accurate picture of where subjects' body fat is located and how it is stored, without any of the harmful radiation effects of X-rays, according to MRI experts...
...MRI procedure, supervised by Bruce R. Rosen, an assistant professor at the Medical School and the director of Clinical Nuclear Magnetic Resonance at MGH, serves as the main emphasis of the entire project, entitled, "MRI--of body fat, ovulation, and estrogen metabolism...
...magnetic resonance- imaging machines. The magnets' powerful fields first align the atoms of the body. Then a pulse of radio waves knocks them momentarily out of alignment. When the atoms return to their previous attitudes, they emit radiation that produces detailed images of the body's soft tissues. MRI machines in use today are enormous (6 ft. by 8 ft. by 10 ft.), largely because of the more than $100,000 worth of bulky insulation required to preserve the liquid helium coolant, which costs an additional $30,000 annually. The improved economics of the new superconductors, says Walter Robb...
...from determining which is the best city, the MRI study promises to add fuel to the debate. The reason is that the computer's indexes measure statistical value rather than emotional appeal. Despite Buffalo's rank of No. 15, for example, most Americans are not likely to be extravagantly moved by the city's charms. But they will probably continue to cherish New Orleans for its fabled zest and beauty- subjective qualities the researchers could not take into account in placing the old town near the bottom of the list...
