Key result
Ultrasonography showed 70% agreement with MRI for hamstring injury locations, with 90% concordance for muscle belly injuries but only 60% for tendon injuries.
Why the study?
Hamstring strains are common in elite athletes, and while MRI is the gold standard for severity assessment, the diagnostic agreement and prognostic value of accessible ultrasonography compared to MRI required evaluation.
Does ultrasonography agree with MRI in diagnosing acute hamstring strains and predicting recovery in elite athletes?
Observational
Does ultrasonography agree with MRI in diagnosing acute hamstring strains and predicting recovery in elite athletes?
High-resolution US is a reliable first-line diagnostic tool for muscle belly and musculotendinous junction hamstring injuries, while MRI remains essential for high-grade tendon injuries.
No takes yet. Share an insight, caveat, or question.
US may support initial imaging for muscle belly injuries; leaves open need for MRI validation in tendon assessment.
Hirahata et al. (2025) conducted an observational in Acute first-time hamstring strains. Ultrasonography (US) vs. Magnetic resonance imaging (MRI) was evaluated on Agreement between US and MRI in identifying injury locations. Ultrasonography showed 70% agreement with MRI for hamstring injury locations, with 90% concordance for muscle belly injuries but only 60% for tendon injuries.
