Quantitative evaluation parameters of acetabulum and femoral head using ct and MRI in patients of different age groups

The quantitative parameters of acetabulum and femoral head normal picture have been studied by computer (CT) and magnetic-resonance tomography (MRI) techniques in 50 adult patients examined for pathology of small pelvis organs without complaints and change signs of the hip in three age groups: the first one from 18 to 35 years, the second one - from 36 to 55 years, and the third one - 56 years and more. The dependences of density measurements on tissue structure features have been determined for CT. Mean density values for normal bone parts are in close connection with structure features, high figures are consistent with subchondral bone and with the zones of force line location, low figures of cancellous bone tissue are beyond the location of force lines. Age-related variations of densities allow to evaluate the involvement of bone zones in pathological process more accurately.
