Being the research nut that I am, I tripped over something that is not only very, very informative, but FREE
It is a PDF file called "Pocket Atlas of Sectional Anatomy" Volume 1, Head and Neck. Search for the title, and you will find it. I can't post the link because there is some advertising on the download site.
Now while it won't show herniated disks, slipped disks, DDD etc., it shows the Axial, Sagittal, and Coronal MRI images of what is normal, and the best part? All the other 'stuff' in there is anatomically identified and labeled! The "slices" aren't as many as we have on most of our MRI's, but there is a wealth of knowledge in that 250 page puppy! I hope my find helps someone.
[my edit] Volume 1 is the only free one presently. Volumes 2 & 3 you still have to buy.
PCTF C4 - T2, Laminectomies C5, C6 & C7. Severe Palsy left arm/hand.
