The objective of this study was to evaluate the role of magnetic resonance imaging (MRI) and ultrasonography (US) in the diagnosis of traumatic muscle injuries.
From June 2003 to June 2004, 81 football players with a history of traumatic muscle injuries to the lower limbs were examined. US was performed shortly after the trauma (from 6 to 72 h afterwards) and MRI within a maximum of 5 days.
MRI revealed 26 minor and 55 major traumas. MRI and US showed complete concordance in 71 patients (site, type and extent of injury). US produced ten false negative results, including six minor lesions and four major lesions. US had a sensitivity of 87.65% in the correct identification of muscle injuries; its sensitivity was 92.72% for major lesions and 76.92% for minor lesions, 57% for delayed-onset muscle soreness (DOMS), 80% for lengthenings, 83% for contractures, 84% for strains, 87.5% for mild contusions and 100% for severe contusions.
US is the first-line technique for examination of muscle injuries. MRI is able to reveal lesions that may be missed at US and provide a more accurate assessment of site and extent of injury.
本研究的目的是评估磁共振成像（MRI）和超声检查（US）在创伤性肌肉损伤诊断中的作用。
2003年6月至2004年6月，对81名有下肢创伤性肌肉损伤史的足球运动员进行了检查。创伤后不久（6至72小时后）进行超声检查，最多在5天内进行MRI检查。
MRI显示26例轻度创伤和55例重度创伤。MRI和超声在71例患者中显示完全一致（损伤部位、类型和程度）。超声产生了10例假阴性结果，包括6例轻度病变和4例重度病变。超声在正确识别肌肉损伤方面的敏感性为87.65%；对重度病变的敏感性为92.72%，对轻度病变的敏感性为76.92%，对延迟性肌肉酸痛（DOMS）的敏感性为57%，对延长的敏感性为80%，对挛缩的敏感性为83%，对拉伤的敏感性为84%，对轻度挫伤的敏感性为87.5%，对重度挫伤的敏感性为100%。
超声是肌肉损伤检查的一线技术。MRI能够发现超声可能漏诊的病变，并能更准确地评估损伤部位和程度。
