Done MRI for brain and spine. Weight not asked. Permanent harm to body?

I have quite a few questions. I just had several mris done this evening. Mri and mra of the brain and mri of the c spine and the soft tissues of the neck, four different tests. I just realized that the tech did not ask me my weight, like all the previous times. 1) If he was off on putting the machine to my weight would that cause any permanent harm to my body? I know that you can get overheated if that is wrong with the energy or something? Like what can it do to you if they put in the wrong weight? 2) This is the first time I got an mri of the soft tissues not just the c-spine which includes the front of the neck and I have a safe mri tiny clip in my neck from parathyroid surgery, would that affect that test at all as I began to get a sore throat and my neck felt tight from that particular test? 3) I was wondering how much different an ultrasound of your neck is vs the mri of the neck-soft tissues, like is an mri much better or are they about the same? 4) Did I really need the soft tissue or does the c-spine cover the soft tissues as well? 5) Also, I still have a major headache from the tests tonight and came out all dizzy and weak and I was not anxious at all, will that go away?
Sorry for all the questions and thank you.

Thanks for writing in.
1.There wont be any permanent damage if the technician has not put your weight, in fact most of the machines won't do a scan if the patient weight is not put. Either he has noted it from your medical records or if you had done MRI previously in the same center, he would have used that data or might would have approximately put your weight.
2.This discomfort which you are getting should go very soon and the clip would cause some small artifact on the image but won't hamper the image interpretation so much.
3.MRI is much better for soft tissue evaluation of your neck, however USG is useful for thyroid and nodal evaluation.
4.C-spine does not cover soft tissues (as the use something called as saturation bands in C SPINE imaging which suppresses soft tissues )of the neck so u would need to get both the scans separately.
5.Yeah, it should pass off after a nice overnight sleep.

Take care and good luck with the reports.

Hi Dr. Jagdale,

Thanks for answering all my questions. I just have a few more if that is alright. I read online that the soft tissues cover from down your eyes down to your chest is that correct? Also, I slept but I am still not feeling well at all from the test. I was actually alright until they did the soft tissue one which was the last one. So then it was good that I got the soft tissue mri even though my ultrasound of my neck was good? I just want to make sure I did not do it for nothing because that test was more my idea than anything to get done and that is the one that gave me the most problems, not sure why?

Thanks so much once again.

Its nothing like that, soft tissues are there everywhere on your body, on neck, thorax,abdomen , hands and legs, they are mostly muscles and subcutaneous fat etc.

Yeah its alright that you got the soft tissue MRI done even when USG was done, but you havent mentioned anywhere what were your complains to undergo so many MRI scans?
I can explain it to you better if I knew what was the indication for your MRI scans, anyways, dont worry no harm would have been caused because of the MRI.

Hi Dr. Jagdale,

Sorry that I didn't explain it more as to why, I actually got the neck mri because of neck pain and numbness and tingling in the arms. I also have been having pain in the front of my neck as well but I knew that the c-spine only covered the spine and the spinal cord but I wanted all around the neck and the sides of the back of my neck that is why I got the soft tissues as well. I got the brain mri and mra because of the numbness as well and headaches etc. My main thing was before getting the tests done that if I really needed the soft tissue since I got the ultrasound done beforehand if the mri really showed that more than the ultrasound would have shown, if that makes sense.

I just don't know why I feel still not good from the mri as well.

Thanks so much and sorry to bother you once again.

Thanks for writing back.

I don’t think a soft tissue MRI would cause any harm to you when you have already undergone a cervical spine MRI without any problem.

If you still feel sick from the MRI I would suggest you to go and consult your treating doctor as there might be some other reason for your discomfort.

If you have got the results of MRI those also you need to discuss with your doctor and see whether your symptoms are explained by them.

Doing a neck MRI is still a better choice to rule out your doubts after a normal USG.

Hope this helps you.
