Longitudinal Study Comparing Sonographic and MRI Assessments of Acute and Healing Hamstring Injuries

Abstract

Sonography is as useful as MRI in depicting acute hamstring injuries and because of lower costs may be the preferred imaging technique. However, MRI is more sensitive for follow-up imaging of healing injuries. The longitudinal length of the strain as measured on MRI is a strong predictor for the amount of time needed until an athlete can return to competition.
