What do MRI results mean when they say level C5 C6 mild diffuse spondylotic disc protrusion noted causing ventral compression with thecal sac?

C5-C6 is the lower portion of your neck. The palpable bump on the back of your lower neck is C7, so we are talking about one disc level above that. This is not serious. A disc protrusion is really a disc bulge, meaning the disc is bulging or protuding out of the normal disc area between the vertebrae. In your case it is bulging anteriorly, (ventral) or towards the front. You probably have some nerve impingement, maybe numbness/tingling in your arms or thumbs. Surgery is not recommended for this mild diagnosis. Your best bet is a chiropractor who will release the pressure on nerve and traction the neck to allow the disc to come back into place.

Can you have an mri while using mirena?

Yes, you can have a pap smear if you have any IUD, including Mirena. Colposcopy and LEEP can also be done with Mirena in, if needed.

Is vp shunt safe in 1.5t mri?

Yes it is perfectly safe up to 1.5T

This is an entirely inadequate answer! There are several shunt valves that are magnetically activated and need to be re-calibrated immediately after a MRI. The shunt and valve need to be positively identified before a the scan and then the specific manufacturers recommendations in regards to scan parameters and re-calibration must be followed. MRI Safety.com is a good resource to check these things out. I have been a MRI Technologist for many years and have seen this issue come up many times.

Advantage and disadvantage of Nuclear Imaging?

I think MRI is important because if you didn't have it you would not have X-rays.

If you did not have X-rays you can not see your bones when they break.

How can you tell if you miscarried during an MRI?

Sometimes you will not now for a few weeks. I just had a miscarriage this week. I was 10w4d along. I noticed blood when I urinated. I called the Dr. right away. I was tested for a UTI then sent in for a ultrasound. The ultrasound showed the fetus stopped developing at around 7 week. It just took a few more weeks for nature to take its course. That is when you will know. There is know doubt after that starts.

How is MRI contrast administered for a brain MRI?

MRI, or Magnetic Resonance Imaging, is an imaging technique using a very powerful magnet and sophisticated detectors or 'scanners' to obtain very detailed images of any part of the body. There is no radiation or x-rays involved. The MRI can be non-contrast, contrast, or both. If both, the non-contrast proceedure is done first. No matter what part of the body is being imaged, the contrast is injected intravenously. A nurse or specially trained technician will start an IV, usually in the arm, and then the liquid contrast material is injected, and the MRI performed.

What test to find out where ascites are coming from?

An MRI scan is an effective way to see where ascites is coming from.

Can you wear silver when having an MRI?

Generally, no-- if by "silver" you mean jewelry or piercings. These must be removed before you have the MRI. The concern is that certain items might come loose or distort the images, and thus distort the test results. But if you are asking about dental fillings, even if they contain silver, these are not "loose," so they would be okay. According to the American Radiological Society, the following items would potentially be a problem, and thus should not be worn to an MRI:

  • jewelry, watches, credit cards and hearing aids, all of which can be damaged.
  • pins, hairpins, metal zippers and similar metallic items, which can distort MRI images.
  • removable dental work.
  • pens, pocket knives and eyeglasses.
  • body piercings.

Which has more detail MRI or a CTscan?

MRI generally provides more detailed images of soft tissues compared to a CT scan, making it particularly useful for visualizing structures like the brain, muscles, and ligaments. CT scans, on the other hand, are better for imaging bone and detecting certain types of internal bleeding. The choice between the two often depends on the specific medical situation and the type of tissue being examined.

What are people called that do MRI's?

I believe they are called a Radiologic Technologist. However, I am not for sure.

Why would a doctor request a MRI?

To see if you have cancer or cancerous tissue.

What is better for anxiety of mri xanex or Valium?

well,when it's time to get off of them.Valium will be must easier than xanax as far as withdrawal goes.

I like Valium better anyway.It seems more relaxing to me than xanax...which can made some people moody and grouchy(myself included).

Don't take any of these too long..it will be harder than you think to stop taking them and it takes MONTHS to get back to your normal self again.

I know from experience.Got pregnant and had to get off of Valium.It was C-R-A-Z-Y!

They are good at what they do but if you take them every day for even a couple months....you stand a chance of withdrawals.

Just don't take them everyday and you should be alright.

"you" meaning ..anyone reading this.

Can i have an mri if i have surgical staples?

Surgical staples are made of non-magnetic stainless steel, however, you never know how much trace amounts of magnetic material may remain. Every manufacturer has different standards. They'll ask you before the procedure if you have any metal at all within your body, so they'll tell you if it's okay or not. Another option is a CT scan which is just as effective when done with contrast dye. Since I have a lot of metal in me it interferes with an MRI, so I've had to get CT's done for the past10 years.

Can you wear toenail polish for an mri of the foot?

You absolutely must remove your makeup and nail polish. It may not "matter to anyone" but you need to remove any fake substances you would apply to enhance your appearance. I also suggest washing your body gently with dove soap for sensitive skin.

How many MRI tests are performed in the US annually?

It is estimated that there are between 7,000 and 10,000 MRI machines in the US. There are also a number of other machines, frequently referred to as nMR spectrometers, which are essentially the same device, but much smaller and used for chemical analyses.

Why aren't mri scans good?

u have 2 be a certain size to have one of these scans which is a massive disadvantage 4 every1.

This is really not a disadvantage. Patients who can do a web search for the nearest Espree scanner will find that the scanner accept patients up to 550 pounds. The bore opening is 30 inches which is the widest in the world and the bore is alsoonly about 39 inches in depth which makes it the shortest in the world. For everyone being scanner a part of your body will be outside the scanner.

The true disadvantage if any is that if you have a pacemaker or non compatible metal implant you cannot have a scan. Patients should always ask if implanting a metal device is safe and will limit their later options. I have a friend who had a vagus nerve stimulator implanted for seizures but he did not have a complete seizure workup at the time. His MRIs were lousy. He can now never have an MRI and they will never be able to see if he has subtle findings such as hippocampal atrophy or scelrosis or heterotopic grey matter. Our 1.5T OPEN BORE MRI scanner allows everyone to have a comfortable MRI study up to 550 lbs.

What if your MRI scanned frontal and parietal white matter T2 hyperintensities what does this mean?

my husband has t2 intense foci in the subcortical white matter in the frontal and parietal reigon these are compatible with foci of chronic ischaemic change the finding is related to small vessel disease his mood swings are getting worse would this disease be a part of mood swings.

How much is a cat-scan machine?

New or used?

I have seen used machines sell for as low as $10,000. ( keep in mind this is an older machine and probably wont give you the best images compared to the latest technology) But maybe that is all that is needed for the types of scans being done at that location.

I have seen newer machines sell for as little as $250,000 to well over $2,000,000. (yes that's 2 million) Its like the options when buying a car and you pay more for newest technology. Places buying scanners evaluate what options are required for the type of scanning they do.

What are side effects of a MRI with pictures?

Almost none. There are some surgical procedures a patient may have had done, prior to having an MRI ordered, that will not allow them to have an MRI study. A pace maker would be a good example. The magnetic field can erase or reprogram the pacemaker, and depending on the material used move the pace maker or the wires in the heart.

Most modern surgical implants are safe in MRI machines, but it is safest if you make sure to let the technologist know you have had surgery in the past.

I have read some studies (forgive me I don't remember references) when I was doing MRI that stated that some people could have arm numbness when left inside a strong MRI machine for extended periods of time. This seems to effect men more so than women.

I never experienced this nor met a patient who has. The magnets are large and the biggest problem I have seen with the use of them is patients becoming claustrophobic.

The strength of the magnet is measured in teslas from 1 tesla to 3 tesla. Usually over 3 is not considered safe for humans and is only used in research.

How long does it take to do an MRI?

About 20 minutes. But it dependes on what part of the body. I personally think its hard for young children to have MRI scans because you have to stay still for that whole 20 mins, but they do make you very comfortable. Its also dangerous if you wear any metal or have a metal filling or pins in your arm, but they check you beforehand for any metal. The machine makes a lot of noise so they let you listen to music or just wear headphones.

What is the meaning of MRI?

I am not quite sure what the person is wanting to know but, as an MRI technologist, I felt I might be able to shed some light on the question. MRI stands for, "magnetic resonance imaging". We use a magnetic field to image the hydrogen protons in the body that have been subjected to radio frequencies. The term resonance means that these protons are spinning at the same frequency (in sync). Patients may choose to have an OPEN MRI or a CLOSED MRI. The difference is that with a closed unit, the images are better because the magnet is stronger. It is an enclosed tube that is usually open on both ends. An OPEN MRI is usually a table with equipment above you and equipment below you (nothing on the sides). The OPEN is used to image people that are claustrophobic or that may be too large (over a weight limit) to fit inside the CLOSED unit. It is always best to discuss plans with your physician if claustrophobia is the issue. I hope this has helped.

Can you eat or drink water befor having an mri scan on your spine?

It really depends on what the MRI is for. If it is an MRI of your leg, water generally wouldn't have any effect on that. If you are having an MRI of your GI track, then you probably should not. The best bet is to call your doctor's office or the lab that you are having the MRI done at.
