Validation of the ultrasonographic assessment of the femoral trochlea epiphyseal cartilage in foals at osteochondrosis predilected sites with magnetic resonance imaging and histology.

摘要: SummaryBackground Non-invasive imaging tools are needed to screen foal femoropatellar joints detect subclinical osteochondrosis lesions due focal failure of endochondral ossification enhance early management optimise intrinsic healing events. Recently investigations employing 3T susceptibility-weighted MRI (3T SWI MRI) and CT have demonstrated their capacity for diagnosis, but these technologies not practical field screening. We postulate that ultrasonography is a valuable tool the detection lesions. Objectives The goals were 1) describe sonographic features femoral trochlea healthy osteochondrosis-predisposed neonatal foals, 2) validate ultrasound assess cartilage canal vascular archictecture front 3) evaluate feasibility in pilot study. Study design Experimental study. Methods Ultrasonographic evaluation predisposed (n = 10) control 6) trochleas was performed ex vivo compared with site-matched histological sections MRI. The articular epiphyseal thickness, indentation assessed at each ROI. Femoral trochleae foals aged 1, 3 6 months also evaluated field. Results Ultrasonographic measurements strongly correlated measurements. There no difference thickness or between specimens. on ultrasonograms corresponded vessel pattern observed histology MRI. Main limitations The number specimens study limited, present within predilected group, now underway. Conclusion Ultrasonographic examination permitted accurate young promising, screening monitoring managing important clinical sites. This article protected by copyright. All rights reserved.
