Synopsis

Keywords: Radiomics, Bone, Total Hip Arthroplasty, Radiomics, Implant Failure

Motivation: Radiographic texture features have successfully identified differences in osteoporotic bone of total hip arthroplasty (THA) patients but no existing investigations have evaluated MRI-based texture of THA asymptomatic patients.

Goal(s): To quantify and evaluate changes in MRI-based radiomic features of asymptomatic THA patients across four timepoints.

Approach: The homogeneity, orderliness, and correlation of femoral trabecular bone texture was calculated in the proximal Gruen zones of patients with THA in four follow-up susceptibility reduced MRIs.

Results: The homogeneity, orderliness, and correlation of femoral trabecular bone texture was calculated in the proximal Gruen zones of patients with THA in four follow-up susceptibility reduced MRIs.

Impact: Image texture analysis may provide a quantitative measurement of trabecular bone abnormalities in asymptomatic THA patients, indicating an individual’s risk of post-surgical induced osteoporosis.
