Avatar f tn http://en.wikipedia.org/wiki/Magnetic_resonance_imaging 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.
Avatar f tn Can anyone tell me about the PET scan? I know its a machine similiar to an MRI...? My mom has to have one tomorrow. She is extremely claustrophobic--and not a small woman...not big overweight-but not small. On top of being terrified of the results (she has invasive lobular carcinoma..and dr is cking to see if its spread) ...shes really nervous about this scan. Is the machine completely enclosed? Very small? How long does a total scan take? Her Dr prescribed her valium...
Avatar m tn The vice versa is true for MRI. MRI can produce images in any plane but CT scan cannot. CT scan uses X-ray imaging whereas MRI uses radio waves and magnets. Radiation exposure is moderate in CT scan and there is no radiation exposure in MRI. Hope this helps. Please let me know if there is any thing else. Take care!
Avatar f tn s ability to lay still, be in the MRI without feeling claustrophobic, and the urgency of getting these tests completed. I have been in an MRI (3T) for 75 minutes, then moved to a different machine (7T) and was in there for almost 90 minutes without a problem. But I don't have major spasms and I am not claustrophobic (in high school I belonged to the spelunking club and loved my time in caves). Was there a reason why they wanted to do your tests like this? Have we crossed paths?
Avatar f tn How long is a mri with ms protocol usually? I had one and it was 20 minutes without contrast and 7 minutes with contrast on a 1.5 tesla is this pretty standard?
Avatar m tn Just had an MRI scan today and as I was put into the machine a red light was shining into my eyes. After about a minute the machine moved and the light vanished. Was this light laser as my eyes feel pretty sore and gritty.
Avatar n tn When having a Hida scan, Do you lay in a machine such as the one of an MRI or what?
Avatar f tn Hi Tara and welcome to the forum. I don't believe we have "met" yet. My MS was diagnosed on a closed 1.5 Telsa MRI machine. However, the strength of the machine isn't the only factor. The software used to obtain the MRI cuts is just as important. I am lucky enough to have most of my MRIs taken on a 1.5t but it has the best software in the area ,including the academic centers.
745975 tn?1258960922 My Doctor order an MRI scan on my head to check for a Pituitary Adenoma, but she told me to only go in when I was having headaches. I was having headaches all weekend but I feel better today, and probably wont be able to go in for a few days since I need to make an appointment first. Will it matter if I have a headache or not when I go in? If there is an adenoma, won't it show up regardless? I'm just trying to figure out why I should wait?
Avatar f tn m claustrophobic and probably going to have an MRI, not looking forward to it but still I find it a better option compared to a CT scan. By the way, each the MRI and CT scan are somewhat different in their function/purpose, so take that into consideration too. Good luck to you!
195469 tn?1388322888 A week ago, I had my upteenth MRI of the brain and spine. I have been diagnosed with MS for 14 years, so I certainly have had my share of MRI's. I have had a few MRI's on the newer 3T machine so I am not a stranger to that machine. This time, something very strange happened, I would like to get your thoughts about. When the tech was scanning my spine, I noticed underneath me, great heat. It felt like my spine was on fire. I started to sweat profusely from the heat.
Avatar n tn There isa no way to answer that question because the radiation is dependent upon the machine and the technique. Plus there is variability, depending on the machine itself, the year and model, and the calibration. Though I am not a fan of the CT and feel it is used unnecessarily when an MRI/MRA would be more approriate, I would not be overly concerned. The body repairs damage. No x-ray radiation is good for a person, but at times there is a reasonable benefit vs. a risk.
Avatar f tn hi, ive just had the worst expercience of anxiety i have ever had, i was booked to had a MRI scan thinking, no problem ill manage that seen it being done on TV ill be fine, i had no idea i suffered claustraphobia, i was actually fighting for breath and felt like someoe was sittin on my chest i was shouting at the poor nurse guy to get me out, we tried a few times but to no avail, i was left a blubbering wreck, ay advice on what kind of sedative to ask for when i go for a re try and the dose, im
Avatar f tn Do not get it on an open MRI machine! These machines are not strong enough for catching most (and sometimes all) of MS lesions. My first MRI was considered bogus by my neurologist. No lesions showed up. The next MRI showed lesions-- even a large lesion missed on the open one. To answer your question, MS is a clinical diagnosis.
Avatar f tn I have had other MRIs and only go to the open MRI due to anxiety. But the breast MRI will be in a regular machine. I am stressed about it, Anyway, I am wondering how far into the machine you go. Is your face out of the machine or in the machine? If anyone could give me some specific details about your bodys postition during the MRI I would really be greatful.
Avatar n tn A CT scan alone may not determine ALS. It is difficult to diagnose with simply one test.
1453990 tn?1329231426 I had to work really hard to make sure that I got a scan on a 3T machine. I don't understand why neurologists don't always schedule you for the best Tesla available!
Avatar f tn hi, ive just attempted to ave an MRI scan done for ny neck, ive been in constant chroinc pain for months, i thought i would be fine having the scan..boy was i wrong, i ended up a blubbering mess, feel very foolish now, not being able to go through with it, i know i HAVE to get this done....or do I??
1842804 tn?1319756311 MS is as unpredictable in symptoms and disease course as it is the placement and number of lesions it causes. Additionally, the way the MRI was done and the strength of the machine makes it somewhat tricky. The weird thing was that I had an open MRI done and it was too weak to show ANY lesions. When I had another MRI done on a 1.5T machine, I had probably around five show up (give or take). My latest scan had many additional ones show up-- like someone splattered paint in my brain.
Avatar f tn My first MRI showed 2 lesions. My question is the first MRI was done on a new MRI machine at our local hospital, the second one was done on a open MRI machine. I don't know the strenghts of either machine. Can the open MRI machine be the same as a closed machine? Is their any difference? Because of the results, my GP seems more confused than ever.
Avatar m tn I just had an MRI on my eye due to pain.It ended up being a minor sinus issue. There was also mention of an "Artifact" on a single slice of the MRI. They have suggested a full brain scan as a precautionary measure. My Doctor say this is common and there is absolutely nothing wrong with me (no tumour or cancer) and I have no need to worry. Should I be? Could it be a tumor even thought it was only on 1 slice?
987762 tn?1671273328 As a result, an MRI examination can cost several thousands of dollars, as it includes a charge for using the MRI machine to perform the scan, as well as a professional charge for a radiologist to view the images. In the end, the MRI machine is a miracle, as long as you don't have a pacemaker, metal hip replacement or metal ANYTHING replacement, and you can afford it.

2076644 tn?1331837159 Was at the doctors today had a scope to my stomach have palaps in stomach but there benign, also have 3 spots on liver,had CT scan they recommended mri, could not do test due to clastfobia, doctor thinks beign, but not sure recommended CT scan in 6 months to see if ther is any chang in size, doe this mean it could be cancer , very upset due to family history father colon cancer, mother stomach cancer & brother lung cancer, all died, need some help to know what I have to deal with.
Avatar m tn Just had a brain scan via MRI. I have a scalp condition - probably lupus. The pain started at the site of recent biopsies and started to spread across the top of my head towards my eyes - then I pushed the emergency button to stop the MRI. It felt like needles poking far into my head. When they pulled me out of the MRI machine and took off all of the gear, my head was shaking uncontrollably. Have you ever heard of that?
