Hi Cinderellamom,
Ouch. Have you had pain prior to the MVA? Your MRI reveals multiple findings. I assume you understand the anatomy of the spine. If not please goggle it. It will be helpful.
Bulging (herniated) discs occur with weakening of the outer fibrous containment ring of the disc. This weakening is often age related and thus unavoidable. It's my guess they have DX (diagnosis) you with arthritis because the changes are so wide spread - and not just confined to one area.
There are multiple medical terms in your MRI that describe each finding. It'd be very lengthy to explain each and everyone.
Facet hypertrophy (Facet Joint Hypertrophy), refers to the enlargement of the facet joint. The facet joints, are the connections of the posterior portion of adjacent spinal vertebrae. Between these joints are nerve roots that originate from the spinal cord and extend to the periphery of the body. When these joints enlarge due to injury or arthritis, the affected person experiences pain, decreased range of motion, and sometimes peripheral neuropathies (such as nerve pain, numbness or tingling).
Stenosis is just a medical term meaning narrowing. In this MRI it means narrowing of the spinal canal or narrowing of an outlet for a spinal nerve.
Diffuse herniated discs represent just another name used to classify the many varieties of bulging inter-vertebral discs. A diffuse disc bulge is a medical diagnostic term often substituted for the more commonly seen broad based herniated disc, although technically, there can be some differences. Diffuse simply means - spread out.
Here's a link to an older thread on MH regarding disc diffusion. The question was answered by a specialist and may be helpful:

It would be difficult to select what (if any) of the MRI findings are a result of the MVA. It may take a good medical attorney to decipher this - a medical professional may not - he/she is probably not interested in any claim you might have against the motorist that struck you. They want to treat you medically and not assist you in any legal claim. At least that's been my experience. I know not all physicians are the same.
The MVA may just have been the trigger to begin painful underlying spinal issues. I hope something I have said is helpful. I wish you the best. Please let us know what you find and how you are doing.
Take Care,
