How is groin pull distinguished from sports hernia?on mri both appear different?

Different: A groin pull is a kind of generic catch all term that is not specific and can be any one of a number of things. It can be a pulled muscle, strained tendon or a ligament sprain. A hernia is a weak place in a muscle that allows something else (often intestine) to push out through the weakness. The appearance of the two would be very different on mri.
