T2 is a measurement of several things a radiologist looks at with an MRI, but radiologists don't actually diagnose, that will be done by your surgeon. Often MRIs don't give a very clear picture and often they can't see some of the things where the problem might be, so you have to combine the diagnostic tests with the exam by the surgeon, assuming you get a good surgeon and not one who's just in a hurry. He should do some manipulations of your body to see what makes it hurt so if he's any good he will neither disregard the MRI nor go exclusively by it. I would just wait for your exam before trying to understand what's going on, and after that strongly consider a second opinion any time you see an ortho. Peace.
High t2 means a higher water content
The best thing you can do is get a second opinion. Some of those technicians that read and give a report on the MRI need glasses.
