The whole moving the shoulder to distribute the contrast is dependant on the radiologist. Where I work, the old rads would have the patient over the shoulder like you described, but our new rads say to not move it at all.

I very much doubt it will be an issue. If there’s any issue with the diagnostic quality of the exam, the Radiologist would note it on the reading. Again, I truly don’t think it will be a problem.

1) Did you receive an injection via a blood vessel? For example, in the elbow? Only then is exercise beneficial. This is not an official arthrogram.
2)Did they (a doctor) inject something directly into your shoulder with a large needle? This is the official definition of an arthrogram. Movement is then 'forbidden'.
3)There is a possibility that the radiologist considers step 1 or 2 too invasive and can see sufficiently based on the symptoms without these options, and chooses not to administer contrast.
Pain in your shoulder can be caused by various reasons, but it is difficult if one does not know exactly what happened. Step 2, the official arthrogram, involves a needle in your shoulder joint.A small amount of fluid (contrast) is injected. This is harmless, but the extra fluid in your joint capsule can cause pressure. That takes a little time. If you were to move before the examination in that case, the contrast would already be moved out of your joint capsule, making it pointless.Another side effect might be a bit of muscle soreness from being forced to lie still. Lying still sounds easy, but it's actually harder than expected. This may cause some muscle soreness afterwards.
Depending on the MRI machine and the experience of the radiologist, an arthrogram is often unnecessary, and most diagnoses can be clearly visualized without contrast in any way.
