Case Discussion

Muscle strains are acute injuries to the myofibril which causes tearing of muscle fibres either due to excessive stretching or overloading. Most muscle injuries in athletes are diagnosed clinically and treated conservatively. However MRI offers unparalleled resolution with accurate grading capabilities and high sensitivity for diagnosis of acute and chronic muscle injuries as well as tendinous ruptures.
