The best way to have a better understanding of your own MRI is to "listen and Hear what your doctor has to say about it."
Have your own written copy of the MRI with you in hand, along with a notebook and pen to write down everything he says.
At any time, you don't understand something your doctor says, stop him and ask him to repeat it or explain it better for you, tell the doctor that you don't understand what he/she said.
Go over every little thing that is reported on your MRI with your doctor so that you have a full understanding of everything.
You said your doctor said it is "to risky" to do surgery". Ask why, get a very detailed answer from him.
It may be that the doctor is saying that because it is true, it may be because the doctor is not experienced in the type of surgery you need or not up to date in new procedures that you could help you.
In one of your posts you said the doctor mentioned cancer to you. Ask why, what is in the MRI that might mean that. What is the doctor suggesting to you, if that is a concern.
Another good thing is to bring a trusted person with you to all your doctor appointments. Be sure that the person you bring with you won't be afraid to also ask questions, get further details and information with you.
It's always a good idea to do this anyways.
Write everything down so you can look at it after you get home as well.
If your doctor refuses to satisfy you with explanations, then it's time to just take your MRI films and/ or disc and just see other specialists. Any doctor that refuses to take the time to explain in detail so that a patient can understand all that is going on and what the MRI reading means vs the symptoms that the patient presents with, is not a good qualified doctor and shouldn't be used.
I would also get several other opinions and do all the same things above that I suggested.
You will get the answers to your questions with a good qualified spinal surgeon. That is the appropriate place for your questions.
This forum, nor is any other forum for that matter, the appropriate place to ask for other members to interpret your MRI readings and tell you what they mean.
Good luck in your search for the answers from a good, qualified spine specialist.
