9. In what circumstances would you use MRI in the assessment/diagnosis of spondyloarthritis?
Part 3 – MRI protocols
10. Please write in text below what your standard MRI protocol for the assessment of spondyloarthritis is (specifying (i) field strength, (ii) sequences, (iii) anatomical coverage and (iii) acquisition planes for each element of the protocol):
11. What is the approximate scan time for this protocol? If multiple scanners are used, please give an average or range.
12. When assessing patients for possible early spondyloarthritis with MRI would you routinely scan?
13. If you do not scan any of the spine in the assessment of spondyloarthritis, why not?
14. If you do not MRI scan the whole spine in the assessment of spondyloarthritis, why not?
15. If you are MRI scanning part of, or the whole spine in the assessment of spondyloarthritis would you perform?
16. If you are MRI scanning the sacroiliac joints, would you perform?
17. When MRI scanning for the assessment of spondyloarthritis which sequences do you use in your protocol? Please tick all that apply.
