tomography as a measurement of periprosthetic acetabular
osteolysis and its correlation with wear  Arthritis Research 
2001;4(1):59-63. Osteolysis, which is considered to be a major
source of morbidity following total hip joint replacement, has
been notoriously difficult to measure accurately, particularly
in the acetabular area. In order to study periacetabular
osteolysis, specialized software for computerized tomography
(CT) scan image analysis has been developed. This software
(3D-CT) eliminates metal artifacts, allows three-dimensional
segmentation of the CT image, and reconstructs the segmented
image to provide an accurate representation and measurement of
volume for osteolytic lesions. In the present study, 20 patients
underwent periacetabular osteolytic volume determination using
3D-CT, functional assessment (using the Harris Hip Scale, the
