Description
Book SynopsisDespite public perception, osteoporosis remains a widespread, devastating disease, and a very serious and costly public health threat. Early detection and treatment must be a priority for primary health care providers. Dual-energy X-ray absorptiometry (DXA) is the principal x-ray technology used to diagnose osteoporosis in its early, asymptomatic stages, to assess treatment efficacy, and to guide treatment decisions. It remains the gold standard today. A DXA Primer for the Practicing Clinician: A Case-Based Manual for Understanding and Interpreting Bone Densitometry is developed around real cases of patients'' DXA measurements. The content is derived from presentations given by the authors at a national society training course and exemplifies not only the complete body of education provided through these lectures but the full range of previously undiscussed nuanc
Trade Review
From the reviews:
“This book details the practical aspects of requesting and interpreting the results of the bone densitometry test. … This is a valuable book for clinicians who order this test, patients who are being referred for the examination, and administrators who fund the studies, because it has a relatively high value clinically although misunderstood. This book should be in every training program library.” (Vincent F. Carr, Doody’s Book Reviews, March, 2014)
