Background Lateral center-edge angle (LCEA), originally described and validated on AP radiographs, has been used increasingly in CT-based studies, but it is unclear whether the measure reliable correlates with that radiographs. Question/Purposes We therefore determined: (1) interobserver intraobserver reliabilities of LCEA measured radiographs; (2) CT scans; (3) intermodality correlation between radiography. Methods reviewed radiographs scans 22 patients treated for slipped capital femoral epiphyses. were reoriented to a neutral pelvic tilt inclination. Three evaluators unaffected hip coronal images corresponded center acetabulum axial slice. Results found an intraclass (ICC) analysis 0.84 0.88 scans. The ICC was 0.96, 0.98. 0.79, lower bound 0.61 upper 0.87. Conclusions Our data suggest scan
