This fully updated and dramatically expanded edition will allow family physicians and specialists to fully understand not only what they need to do, but also why. New to this edition-over half the book-are discussions of the clinical guidelines for selecting patients for densitometry measurements, various questionnaires and indices that have been developed to help patients identify themselves as candidates for bone mass measurements, and specific densitometry applications of diagnosis, fracture risk prediction, and monitoring changes in bone density. Updated material includes an expanded review of the effects of diseases and drugs on bone density, new standardization formulas for the hip subregions and forearm, statistical devices necessary to "test the test," and guidance on how to do a short-term precision study and apply the result to clinical practice. An accompanying CD-ROM contains a Precision Calculator, a Statistical Confidence Calculator for Measured Change in BMD, OST Nomograms, a Patient Risk Factor Questionnaire, and a CME review, which, if successfully completed, can lead to 30 hours of AMA Category I continuing education credit.
