    What does an MRI of the IACs (IAMs) show?

    Posted by Ravi Sohal on Tue, Sep 22, 2009

    mri iac iamMRI scans are frequently used to evaluate the internal structures of the brain. IAC MRIs are a type of Brain MRI that is used to evaluate the structures of the Internal Auditory Canal - IAC (aka Internal Auditory Meatus - IAM).

    The IAC contains among other structures the 8th cranial nerve. This is a large nerve that conducts hearing and balance signals from your inner ear structures. This nerve can become damaged, inflamed or give rise to a tumor commonly called an "acoustic neuroma." Most IAC MRIs are ordered to rule out an acoustic neuroma in patients who are experiencing dizziness, ringing in the ears, hearing loss, fullness, for example. Although these tumors are slow growing and generally benign, they are close to vital structures in the brain and can be difficult to treat.

    An MRI of the IACs is done with MRI dye. The dye helps detect small tumors and subtle inflammation that a non-contrast MRI may miss.

    IAC MRIs also include the cerebellum, brainstem, vessels of the back of the brain and other nearby structures. Some IAC MRI protocols also include a few scans of the entire brain.

    Your MRI IAC Scan

    An MRI of the IACs generally takes about 30-40 minutes or so to complete. If you are going for one, wear loose comfortable clothing and remember to remove all metal (jewelry, phones, rings, etc) before going into the MRI scan room.

    This test will be done with IV MRI contrast. The first part of the test is done without contrast. Then the scan is paused and the table on which you are lying will be pulled out (remember don't move!). The technologist will then inject the IV dye and return the table into the tube for the remainder of the scan.

    If you're insured, you may need to have your test authorized (approved) by your insurance company first. If you're uninsured and need to look up prices and buy an MRI scan of the IACs (IAMs), you can use our website to look up MRI scan costs and then purchase with your credit card.

    Have you had an MRI of IACs scan? What was it like? Please leave your comments below.

    I had an MRI scan today for my brain and spinal cervical, with the contrast dye included. I found no problem with the procedure. Although the scanning machine was extremely noisy and i could not hear the music i felt perfectly safe. It made my head spin slightly, but at one stage the machine vibrated and i recieved a good massage!! With regards to the contrast dye, my arm bled quite severely after; however, i believe this to be no fault but my own veins! It must have been a good one! Other than this, i found the experience very noisy and reasonably uncomfortable, but perfectly fine.

    I have had 14 MRI's on my brain since 1988 and all with contrast. The last one was 11-2008. I had some x-rays done last week on my spine and the Dr said that my spine is loaded with contrast. Does this stuff ever go away?

    I had an MRI without contrast for IAC which was not protocol, but the nurse made a mistake when called by the tech without checking with the Dr.. The original order was for an MRI with & without contrast & slices thru the IAC & an MRA brain & skull base with & without contrast. I wanted to get contrast once which was why I had all tests done at the same time. My question is how long beforeI can get contrast dye again & what should I be cautious of. Also the injector broke twice I weigh 160 lbs. how many ml of omniscan should I have gotten.I anyone can ease my pain please contact me.

    I had a MRI ten days ago and I still am having pain in my hand and arm from the IV where they put the contrast. Has anyone had problens like this? Also, caught a cold the day after my MRI and stiil am not feeling well ten days after. I will never ever has an MRI with contrast again.

    I am glad that I went on this site because I have another MRI to go to tomorrow and wanted to check on the adverse reactions to MRI contrast injections. I find the people really nice (except for the under qualified injection nurse who took three attempts to get at my unusually large veins - I just laughed cause I was thinking "how the **** can you miss!"). Lets just say that I'm a tough woman.  
    With the last mri, my bladder was extremely effected where I had to use the washroom a lot more and for almost no reason. Also, shortly after getting the injection, I had the fun of displaying extreme rashes on my face and upper body. Upon reading the experiences of others after getting the injection, I don't believe in a high frequency of such coincidences so this time around I choose not to opt for the contrast injection.  
    The actual mri experience is always fine with me. I find them relaxing and always fall asleep. The technicians are really nice people that totally put me at ease :)

    i had my 3rd mri done on my brain and spine today. 3 hours long. ugh. all spanning over a year. i have had no reaction so far. the contrast was uneventful other than the tiny needle stick. i know it makes some people sick. my doctor says every once in awhile, people vomit. but for me, nothing. didn't even know it was in me. the scan is long and uncomfortable because you have to lay so still. i took an eye cover to help relax. it helps if you don't open your eyes, then you never really know your in the tube!

    I went to have a Mri of the head and IAC's with contrast. But I freaked out so they had to stop the scan and reschedule me to come back. Just something about being caged in and blind folded I could handle that. Is the Open Mri better than the closed one?

    I just received a bill from Sutter Hospital in Santa Rosa, CA for a Brain MRI scan with dye. They billed me $5696.60 for the 40 minute procedure. My insurance paid $3484. of the bill and I ma on the hook for $2100.! This is 2.5 times the average cost of the procedure at independently run facilities. The good news problems. I suggest you shop around before booking the test.

    I had a MRI with contrast today. It was totally fine. I think the most important advice I would give would be to go to the place where you will be having it done or phone up. Have a chat to the people that will do doing the scan for you. I understood it was loud and I could choose Music (very good idea as its so loud and i went in the scanner head first). Also I asked for just a butterfly needle to have the contrast. This is a smaller needle than a normal IV venflon/canula. Because the amount given is not normally much this needle is more than big enough. Closing your eyes helps alot too. 
    I didnt have a single reaction to anything. Its always a risk if you have never had a drug. but its quite rare and you never know till you try. 
    I felt slightly light headed when I got up but it think this was do to lying down for almost an hour very still and the machine does rock a little too (depending on the type of scan). But after a large glass of water I carried on and went back to work. I wouldn't think twice if I had to have it again.  
    Easy Peasy and if it takes that to show whats wrong with me then great :-)

    Three MRI's with contrast. No reaction to the contrast. The MRI proceess is taxing in that you are lying in one position for as much as an hour, depending on what they are looking for. The only break is when they pull you out of the machine to inject the contrast med, all of 30 seconds. If you are claustrophobic you may have a problem lying in very close quarters for the time necessary to complete the test. Other than the noise and vibrations of the machine, the test is more a test of one's patience or will to see it through to the end.

    I had an MRI with contrast done of my head today. The technologist talked to me periodically throughout the procedure, hardly knew when the butterfly cath/dye were inserted. No reactions afterwards. You have to remain perfectly still but overall not an uncomfortable test as they go.

    I had an MRI with contrast, of the brain/brain stem because I have an allergy to the CT scan dye (iodine). The tech had me lie on my back, comfy bolster placed under my knees, and comfy pads placed around my shoulders. A squeeze buzzer was placed in my hand if I needed the tech to stop/come to me. Head comfortably stabilized with the pads so I wouldn't turn/move my head. A plastic frame was placed to maintain the pads in place, but was not near /on top of my face. Tech offered if I wanted my eyes covered, I declined. Soft foam ear plugs were given...first pair I've ever been able to pressure, comfy in the ears(you still hear the Tech, dulls the noise of the machine). Tech inserted the catheter in the crease of my arm, flushed the catheter with saline (water) to insure an open vein. Had the scans done without the contrast dye for 30mins. The noise in the macine varies: tapping, angry woodpecker tapping, guitar tuning, one sound reminded me of the emergency broadcast system. It is not scary..I promise. Just tell yourself a total of 45mins for this whole experience to be over and done with, gives you peace of mind that it's over.Tech pulled me out after 30mins,told me the dye contrast was being put into the catheter and it might feel cold...didn't feel it at all going in. When the scan started up again, I felt flushing(heat) in my face/head for about a minute(normal)..not uncomfortable.Scan was over in 5mins after I received the dye. Catheter removed without pain, bandaid applied. No after effects,little tired later in the day(I was a little nervous prior, which is why I was tired). Do drink lots of water the day of test so Tech can find vein, drink lots after test to avoid headache(others told me this). I thanked God for calming my fears, and helping me through it all;)It was a good experience, and with positive thinking, you will have a great outcome too!

    Since Nov. 2009 I've had 6th CT SCAN and one PET SCAN. Never having a reaction to the dye till this past July 20th. I have perfectly good big veins, the nurse could not seem to get the IV 
    and after the scan my hand was swollen for two days and then I started with a rash on my wrist that has spread all over my body making it impossible for me to do anything, I cant even sleep. I went through 6 cycles of chemo for non-hodgkin lymphoma and I dont remember having so much disconfort from the chemo as I am having with this allergic reaction. I am on my 6 six months remmission and I dont know what my oncologist is going to do but I refuse having any more contrast put in me.

    I just had an MRI of the brain and cervical spine. I am hurting from carpal tunnel syndrome in both hands and also my neck. Will be seeing my neurologist tommorow. The MRI with and without contrast also does not really bother me. I was in there for over an hour. My back was killing me.I think the dye is useful but not without a few side effects.Good luck to all..

    I had an MRI done, but I didn't have to take any thing for it - the next morning I woke up with a rash across my chest and arms. Does anyone know why this might be?

    MRI w/dye also got rash on wrist and underarms. How long does this last and what to do ?

    It sounds like you may have had a minor reaction to the dye. Let your doctor know and he/she can give you some recommendations regarding treating it.

    I had an MRI on April/2011,the nurse gave me an injection. After a week I started feeling some itching and my shoulders and arms burnt. I saw my primary doctor, he gave a couple of blood tests and said everything was ok. he sent me to a specialist of allergies. This Doctor gave me some medication for allergies. I do not feel any improvement. I am really concerned about this problem. I have never had allergies in my life. Any advice will be appreciated.

    I am aged 52 with diabetes 2 and arthritic. had mri with contrast due to neck problems had no problems at all. 2wk later was called back for another mri this time without contrast. the reason I had contrasdt first time was because they wanted to check for a tiny brain bleed. the second mri focused on the spine. the medical experts do the best test for your symptoms to get the best diagnosis to help you. talk over any concerns to them. the mri dosent hurt, expect strange noises but relax they give head phones with music or ear plugs, you have a panic switch to talk if needed to operator but u will be fine. best wishes jayne, south yorkshire.

    Awful experience with MRI. I went for pain and noise in my ear and pain in neck jaw area. The technical asked a few questions, and told me there was a speaker and I could reach him at any time, it was to be with contrast. The noise was unbearable for me. After 40 minutes I started calling him to let him know, my head felt like it was going to explode. He never answered after 5 mts I started trying to flag him with my FEET and Blank flying in the air, nothing. I jump out of the machine and when I got to the door it was LOCKED by this time I was a reck. He suddenly appeared out of no where and asked what happened why did you jump out I was so upset I could not even talk. Shortly there after he was let go. I had written a letter to the insurance and CC he's office. I am currently having to have another one and now I am not sure what to do. is open MRI better??

    I recently had a second mri with contrast, the first was done about 2 yrs. ago. I was more concerned with being poked with a needle than any side effects. Precautions are taken to minimize the chances of any potential side effects. Prior to the procedure questions are asked regarding allergies, diseases, any concerns, etc.. Bloodwork or any other tests are done as well if neccessary. I had no problems with either of my mri's.

    I've had several mri's without a problem. My only complaint would be the noise, which you are made aware ahead of time. Some headphones and your choice of loud music or a monitor above with a tv program of your choice would probably be a good thing.

    just had MRI brain scan this morning with contrast. Shortly after the injection i experienced chest tightening and this was quite scary as i thought the cardiac muscles were constricting however within a minute of the procedure ending and with sitting up the pain ended
