Muscle injury and strains are very common among athletes. MR is the preferred method of evaluation because of superior contrast resolution, reproduc-ibility, and excellent anatomic detail. Ultrasound is also useful and advocated by some as a front line diagnostic modality because of its lower costs and portability particularly in experienced hands. It is important to remember that injury usually occurs at the myotendinous junction, which may be intramuscular in the hamstring and quadriceps muscles. The size of injury and relationship to the myotendinous junction can provide prognostic information regarding convalescent period, which can be extremely important for the elite athlete. Literature on prognostication is limited and probably results from relative commonality and mild nature of most injuries but further studies are warranted as injuries could affect different sporting population more than others.
Future developments regarding treatment will become more important and analysis and classification of imaging finding may provide better prognostication. For example, some have identified the importance of the COX pathway for muscle injury healing and possible deleterious effects of inhibitors (ie, non-steroidal anti-inflammatory drugs) . Others have experimentally shown the introduction of relaxin growth factor via gene therapy promotes muscle healing [138,139]. With new treatments on the horizon it is important to have supportive objective and accurate information regarding extent and types of injury to help stratify treatment groups and improve patient care. Precise reporting of the location of muscle and tendon injuries is needed, as prognosis may be different. Therefore continued evaluation and classification of muscle and tendon injury with imaging, such as MRI, particularly for the elite athlete should be performed.
