title: [Estimation of bone mass of hemodialysis patients by digital radiologic radiogrammetry (DXR)].
abstract: Bone mass (BMD) may be evaluated by digital X-ray radiogrammetry (DXR) which it is estimated from multiple cortical measures carried out on five regions of interest over a simple hand-forearm X-ray film. We included 168 HD patients (108 men and 60 women; 63 +/- 14 and 66 +/- 12 years old respectively--p < 0.05-) coming from seven HD units in Asturias. We performed a hand-forearm X-ray, an epidemiologic questionnaire and we revised their medical and analytical records. As the normative data we used the measurements of a random sample of 247 subjects from our own population. The prevalence of osteoporosis was 7% and 40% in men and women respectively. BMD was correlated with weight (r = 0.346), time on HD (r = -0.188), time on treatment (r = -0.235). The porosity was correlated with PTH levels.
