The above link tells you pretty much everything you didn't want to know about MRIs. I had a brain MRI one time, I had to be sedated because I was afraid of it, they even have a little mirror in there so you can see out of it, sort of claustrophobic in the machine, and they had a microphone and radio in there so I could talk to the techs. When the machine started up, it was VERY loud, surprised me, kind of made a bumping racket.
MRI uses a magnet. The image is much clearer and via magnet vs. sound wave. MRI is good for viewing soft tissue and organ, and if you get one with contrast (Gallium), vascularization can be seen. MRI is good for determining size and shape of the liver. You can also see lesions (carcinoma) on MRI. A radiologist can determine a rough density from an MRI which is good for determining fibrousness of the liver. Cirrhotic nodules can also be visualized via MRI.
If the metal you have in your body is not close to the pancreas, they can do a CAT scan, which is radiation like X-rays rather than a magnetic field of MRI, so metal doesn't goof the whole thing up. They can also do a needle biopsy, too, the CAT scan guides the surgeon to the correct place, but the amount of tissue that needle can take is sometimes too small to be sure if the mass is benign, but if it shows up as a cancer, well, they will likely want to do surgery and so forth.
m assuming they used metal surtures/staples during removal. Two years ago, I had a MRI scan for pain in my knees. Since then I had pain in my right side just below my rib cage. It was an acute pain immediately after the MRI scan. There is still residual pain to this day. Is it possible that something tore open? If so, can this be the cause of sharp pains in my mid back that the doctors have not been able to pinpoint after X-rays?
The hardware is normally made from either stainless steel or more likely titanium. Nither is a "ferrious" metal. Only Ferrious metal reacts to magnetic fields. No way an MRI Pulls on hardware that is used in your body. If it did, it would rust!!!!....LOL. It's amazing what our head will do to us when we are in that tube.....................
First step is usually part of the informed consent process and involves disclosing any metal you may have in your body, and the professionals go from there. I know our questionnaires prior to each MRI ask about tattoos (metal in some inks), angle-grinding, gunshot wounds, metal medical implants, etc.
Not to say those discount being able to have an MRI automatically, just that the radiologist needs to know about them in order to make the call.
ggreg's info may be overly cautious.
If at all possible, you should get the implant card or operative notes that can identify specifically what aneurysm clips were placed (manufacturer and model) because there are two different concerns with these...
The greatest concern is that the clips are made from a (ferro)magnetic material, in which case they can twist and pull near the powerful magnetic field of an MRI. This can be fatal and should not be understated as a risk.
You would think it would be detected being metal. Working with strong magnets, an MRI scan can be dangerous with stents, it can even make them very hot. Before an MRI the technician has to be told the type of stent/s in the patient, which included the manufacture, model etc. Also the size has to be known. The technician then adjusts the sensitivity of the MRI scanner so no danger to the stent is presented. Maybe the scanner was adjusted to a level where it was unable to detect the stent.
How necessary is it to have a CT head scan for having one possible simple partial seizure two months ago? I saw a neurologist who suggested I have the scan, but he did admit another neurologist might have said it was okay to wait and see if it happened again. He left the decision up to me. I'm worried about the x-rays of a CT scan, having had plenty of x-rays for other procedures in the past. If I have another seizure or whatever it was, I would definitely have a scan.
I think you need to tell the technician before your MRI. They should know if you have any metal in your body because and MRI can move metal objects, this is from what I've read anyway.
I'm wondering why your Dr doesn't want the tech to know? That doesn't make any sense.
If it were me in your situation I would call my Dr and ask why he doesn't want anyone to know and tell him that it may not be safe for you to even have an MRI if you have metal in your body.
Sometimes older kids would come by and pry the lids off the barrels and throw the sludge at us. This would end up in a sludge free-for-all. I have many neurological manifestations with normal MRI, CT Scan, blood tests, etc. I do not however, think I have been tested for heavy metal poisoning. All the docs I have been to say it's just Fibromyalgia or histrionics. Could this past exposure be to blame for my symptoms? Thank your for your consideration.
I never had pinguecula prior to the MRI, and did not "age or have too much sun exposure" overnight. I have 24 hour urine tested positive for gadolinium retention 5 months post MRI. Now that urine testing for Gd is available, more and more people are realizing their mysterious and undiagnosed symptoms are Gd related. Please educate yourself on the yellow plaque (similar to pinguecula) caused by gadolinium and referred to as a symptom of NSF.
Well, very rarely the radiowaves used in MRI may causes increased sensitivity in a few individuals and this associated with increased blood flow to the region nay be responsible for the discomfort. Adjusting the intensity of the microwaves may help alleviate the symptoms.
Hope the information is helpful.
Take care!
