Hi estevezkid66
Welcome to NeuroTalk

.
I hope that you will find the NT community as knowledgeable and supportive as I have.
I don't know much about the details of MRI scans and spinal anatomy beyond saying that the T7 vertebra is about halfway done the back (roughly equivalent to where your seventh and eighth pairs of ribs are).
The "
Spinal Disorders & Back Pain" forum within NT is worth checking out. It is absolutely fine for you to start your own thread there. Other NT members should be able to offer you detailed thoughts and suggestions.
All the best.
