Until recently, treatment has generally been limited to prescribing supplemental estrogen, to slow the resorption rate, and calcium, to facilitate the formation of new bone.* Using a computerized axial tomography scanner, doctors at the University of California in San Francisco are able to take three-dimensional X rays of the bones, measure the loss of minerals and devise an estrogen dosage sufficient to maintain the resorption balance. Says Kaiser-Permanente Endocrinologist Dr. Bruce Ettinger, who does research at U.C.S.F.: "We've been trying to find the smallest dose of estrogen that will prevent osteoporosis. I think we have...

It is a cousin of the CAT scanner that nearly a decade ago wedded the technique of X rays with computer technology to give cross-sectional views of internal body structures, not just bones but soft tissues as well. But scanning by CAT (for computerized axial tomography) is limited to anatomy. It lets doctors see an organ's shape and form, but cannot tell how it is functioning. PET (for positron emission tomography) allows the physician to examine the brain and body in ways never before possible, providing metabolic portraits, and revealing the rate...
