Stock Photo - BONE DENSITOMETRY RESULT<BR> <BR>Bone mineral density test (lumbar vertebrae). This methods measures the subject´s bone mineral density (BMD), and can detect osteopenia (a decrease in bone density) and osteoporosis (pathological reduction in bone density). The chart indicates the patient´s BMD (in g/cm2) for their age. Here, a BMD of 1.05 g/cm2 corresponds to a normal BMD for a person of this patient´s age. The T-score and Z-score indicate the variation between the subject´s BMD and an average value which, for the T-score corresponds to that of a population comprising members of the same sex and age group (20-30 year-olds, the age group in which bone density is at its peak), and for the Z-score, that of a population of the same sex and age. A T-score of between 0 and -1 indicates a normal BMD, between -1 and -2.5 indicates osteopenia, and below -2.5 indicates osteoporosis. Here, a T-score of -0.15 corresponds to a normal BMD, and a Z-score of 0.75 means that the person´s bone density is above the average score for individuals of their age. Results can also be expressed as a percentage.
