Tomografía computada cuantitativa tridimensional (QCT-3D) para la evaluación de masa y arquitectura ósea / Three dimensional quantitative computed tomography (qct -3d) for the assessment of bone mass and architecture

ABSTRACT

From a clinical point of view, three dimensional quantitative computed tomography has not replaced dual energy X ray absortiometry (DEXA) as the test of choice to assess bone mass in adults and children. This is particularly true in postmenopausal osteoporosis and in patients without significant disturbances of body size. However, in particular diseases such as skeletal dysplasia, Turner syndrome and other endocrine diseases associated to stunting, QCT-3D can provide accurate information about bone health. It is also informative when the trabecular/cortical bone ratios are altered. QCT-3D is widely used for research purposes and it became available in Chile recently.
