Purpose To evaluate the diagnostic utility of ultra-short echo time magnetization transfer (UTE-MT) MRI in detecting early microstructural cartilage alterations within the tibiotalar joint before and after prolonged running in amateur marathon runners.
Read more Methods and materials Running-related musculoskeletal injury (RRMI) is a common occurrence among runners. Magnetic resonance imaging (MRI) plays a crucial role in diagnosing knee joint abnormalities and grading injuries affecting the cartilage and other structures of the knee joint. Ultrashort echo time (UTE) sequences, with echo times (TEs) approximately 10 to 1000 times shorter than conventional fast spin echo or gradient echo sequences, have been developed and utilized for imaging both short and long T2 tissues, as well as tissue components within the...
Read more Results UTE-MTR measurements demonstrated robust reproducibility [ICC: 0.860 (95% CI: 0.816–0.896)] and excellent inter-rater reliability [ICC: 0.946 (95% CI: 0.941–0.950)]. Transient UTE-MTR reductions were observed in most cartilage subregions at 48 hours post-exercise, followed by recovery to baseline after 4 weeks of rest (Fig. B). Post-Exercise Changes (48 hours): Medial compartment: Significant decreases (P < 0.05) in UTE-MTR values were observed in the anterior tibial cartilage, middle tibial cartilage, and middle/posterior talar cartilage. Lateral compartment: Significant reductions (P < 0.05) occurred in the tibial...
Read more Conclusion UTE-MT MRI enables quantitative detection of exercise-induced microstructural remodeling in tibiotalar joint cartilage. These findings position UTE-MTR as a sensitive biomarker for monitoring early cartilage adaptation and recovery dynamics in response to biomechanical loading.
