re; kidney failure caused by the contrast dye.

i thought you had a shoulder injury? the contrast dye is for tumors - that's why i was confused. shoulder injury is not a tumor. believe me i know shoulder injuries - have them myself!!

Re: MRI with contrast

You really should stop posting since you are obviously way out of date with what happens during MRI's so how can you even know about the dangers of contrasts? I have had 4 MRI's with contrast in 2 different locations and have never has a tumour or even been suspected of having them. The contrast shows up injuries or abnormalities much more clearly simple as that.

No, that's not quite right. You can have an MRI of a joint with contrast to see what's going on there - here's the first reference I pulled up - there are probably many more.

And as it clearly states in the link you posted, the indication is for patients who already have a renal insufficiency (kidney problem) - and if you read the thread, that was checked before the test was done.

Re: MRI with contrast

I will try to make it simple: MRI is based on detecting a signal that comes from water and as in some parts of the body the signal is not strong enough a contrast agent is used. In the market there are contrast agent that are specific (e.g. tumors) but in general MRI contrast agents are injected in the part of the body to be scanned to enhance the signal locally and have no biologic effect.
They are different from other contrast agents (dyes, etc) as they are based on the magnetic properties, therefore Gadolinium is used. Whilst Gadolinium itself is toxic, in contast agents it is bound firmly in a sort of chemical cage and is never released in the body. It would require by far longer than a lifetime to release a minimal amount of Gadolinium, and even if you would be lucky enough to live centuries by the time this happens the whole contrast agent will have been eliminated by your body and ended up in the sewage system.

Re: MRI with contrast

Glad you're feeling better today, Nil.

It kind of surprises me that they injected the contrast dye directly into your shoulder. I had an MRI about 2 years ago, and the gave me an IV and injected the dye directly into the IV line. But they probably do things differently according to what part of the body is scanned.

Now I have another MRI (for something different) scheduled for this Friday. Ugh. Good times.

Re: MRI with contrast

It does depend on the location, I've had hip MRI's twice and both times I was injected directly into the hip joint. This is done during a an x-ray so the the needle is positioned in the joint in the correct place (ouch!). The other times I had an IV.

All the best for this Friday!

So it was painful for you too? Great, I am not the sensitive one. Ouf! Funny enough (not) the doc made a local anesthesia before to inject but I felt it very very well! And weird enough, my shoulder and upper arm are still a bit numb since Monday evening.

Re: MRI with contrast

The first time was painful and afterwards my leg went numb and I had trouble walking until the next day. The second time I think I had a more experienced Dr doing it and I had no problems though the injection itself was a little painful. I never had any anaesthetic either time. I have a high pain threshold too so I was not being a wimp about it.

Thanks! I remember having a question about kidneys. I didn't know what kind of contrast I had, I am happy you told me!! I just know how painful the injection was and the very very long minutes I spent in the machine. My very next question will be about prosthesis.

If it was for kidneys... i had a CT last week and ya they give me iodine for contrast... they stinged to my nerve and I felt a little weird for few seconds and thats all.. it was all good later... I infact went to work from there....
DId you talk to the doctor regarding this? Did they say its normal?
I would get worried on the swollen part..

Re: MRI with contrast

....and most importantly, if you directly inject contrast into the joint, you get really cool pictures like this!



It's really good for highlighting inflammation, scar tissue and tears.
