Using multidimensional topological data analysis to identify traits of hip osteoarthritis.


ABSTRACT: BACKGROUND:Osteoarthritis (OA) is a multifaceted disease with many variables affecting diagnosis and progression. Topological data analysis (TDA) is a state-of-the-art big data analytics tool that can combine all variables into multidimensional space. TDA is used to simultaneously analyze imaging and gait analysis techniques. PURPOSE:To identify biochemical and biomechanical biomarkers able to classify different disease progression phenotypes in subjects with and without radiographic signs of hip OA. STUDY TYPE:Longitudinal study for comparison of progressive and nonprogressive subjects. POPULATION:In all, 102 subjects with and without radiographic signs of hip osteoarthritis. FIELD STRENGTH/SEQUENCE:3T, SPGR 3D MAPSS T1? /T2 , intermediate-weighted fat-suppressed fast spin-echo (FSE). ASSESSMENT:Multidimensional data analysis including cartilage composition, bone shape, Kellgren-Lawrence (KL) classification of osteoarthritis, scoring hip osteoarthritis with MRI (SHOMRI), hip disability and osteoarthritis outcome score (HOOS). STATISTICAL TESTS:Analysis done using TDA, Kolmogorov-Smirnov (KS) testing, and Benjamini-Hochberg to rank P-value results to correct for multiple comparisons. RESULTS:Subjects in the later stages of the disease had an increased SHOMRI score (P?
