Tailbone MRI: T1 vs T2 / STIR images on coccyx MRI

MRI studies of the tailbone show lots of details of the anatomy of the coccyx region.

But the doctor needs to know which images to look at for the different types of details that can be seen.

  • T-1 images are best for looking at bony structures like the actual bones of the tailbone (coccyx).
  • T-2 images are not as good as T-1 images at showing details of the bones.
  • But T2 images are better than T1 images  at detecting inflammation.
    • Inflammation is important to look for, since this can be a sign of joint arthritis, joint dislocations, bone fractures, bone infections, and other abnormalities.
  • “STIR” images also show inflammation (similar to T2 images).

  • Kaylie

    Thank you for this website. My question is: as a patient, is there a way I can ask the staff to take the most appropriate images?

    (I have had other injuries, and I later found that less helpful images were taken. E.g. a standing x-ray might be ideal, and that didn’t happen. So I’m worried that the same will happen in this case. I’ve just injured my coccyx after a blunt trauma. No images were taken at the hospital, because of concern around irradiating my ovaries. If the pain continues in a week, I’m to go back to get images and different pain medication. I’d like the images to be the right ones and don’t know if or how I can ask for that.)

  • Hi, Kaylie. Thank you for your question.

    I am very sorry to hear about your tailbone pain.

    Have you already read my book on tailbone pain? (available on Amazon at: Link: http://amzn.com/0996453504 )

    There is an entire chapter of the book all about the best tests to get for tailbone pain, discussing x-rays, MRI, CT scans, bone scans, etc.

    Typically the best initial test to check for unstable joints at the tailbone is to have xrays done while the person with tailbone pain is sitting. See:
