Densitometría axial y periférica en el diagnóstico de la osteoporosis

espanolLa absorciometria fotonica dual de fuente radiologica (DEXA) es la mejor tecnica para evaluar la densidad mineral osea y predecir el riesgo de fractura. Comparamos los resultados diagnosticos de DEXA central y periferica. Material y metodos. Estudio retrospectivo de 100 pacientes. Se practico DEXA central y DEXA periferica de calcaneo, considerando osteoporosis cifras -1,5 DE a nivel central y > -0,6 DE a nivel periferico. Resultados. Edad media 55,76 anos, 64,3% mujeres y 35,7% hombres. Densitometria periferica: osteoporosis 34%, osteopenia 29% y normalidad 37%. Densitometria central en femur: osteoporosis 32%, osteopenia 27% y normal 41%; en columna: osteoporosis 39%, osteopenia 26% y normal 34%. DEXA periferica y DEXA central en femur con p > 0,01, mientras que con DEXA en columna con p EnglishDual energy x-ray absorptiometry (DEXA) is the best technique to evaluate bone mineral density (BMD) and predict the risk of fracture. We compare the results of central and peripheral DEXA. Material and methods. Retrospective study of 100 patients. Central DXA and calcaneum peripheral DEXA was practised, considering osteoporosis numbers - 2.5 of a central level and - 1.5 of a central level and > - 0.6 of a peripheral level. Results. Average age 55.76 years old, 64.3% women and 35.7% men. Peripheral densitomnetry: osteoporosis 34%, osteopenia 29% and normality 37%. Central densitometry in femur: osteoporosis 32%, osteopenia 27% and normality 41%; in lumbar column: osteoporosis 39%, osteopenia 26% and normality 34%. Peripheral DEXA and central DEXA in femur (p > 0.01) while with DEXA in column (p
