Am looking for Arnold Chiari 1 malformation, but the doctor said there is no sign of cysts....was not what l wanted them to look for?

Cost of MRI for knee?

The cost of an MRI study can range from $300 to $10000. There is a huge difference in the cost of an MRI study across the country and even city to city. In addition to pricing being very different throughout a region, pricing is also affected by the MRI clinic that you decide to use.

When your doctor orders an MRI, he/she may give you a referral to an MRI clinic in the hospital they are affiliated with an independent MRI facility. The hospital MRI's are usually 4-5 times as expensive as the independent imaging center with no difference in the quality of the scan on most occasions.

I found a center in the Milwaukee market that charges everyone the same price of just $600 for any MRI, no matter what insurance you have. I used them and my doctor was very happy with not only the quality of the scan and radiology reads, but also with the professionalism of the clinic. The name of the MRI Milwaukee Clinic was Smart Choice MRI (www.SmartChoiceMRI.com).

Although Smart Choice MRI has a transparent pricing model where every patient knows how much they are going to be charged, this is very rare across the country and so I would always suggest calling your insurance company and the imaging center you choose to figure out how much the MRI exam is going to cost.

In the Portland and Seattle, you can check out Sprig Health for the cost and description of MRI procedures at a few locations in town (https://www.sprighealth.com/site/all-services). Currently the prices seem to range from $485 to $1190 for MRI with and without Contrast.

What does T2 and Flair hyperintensities mean in a MRI scan?

T2 FLAIR Hyperintensity is when hyperintensity is seen via FLAIR (Fluid Attenuated Inversion Recovery) during the T2, or spin-spin, relaxation cycle. This process helps nullify natural fluid signals in the body to find plaques and lesions in the brain. Hyperintensity describes areas of high intensity in the brain during an MRI.

Why might some health authorities say yes to doing MRI scaners on everyone over 40 while others say no?

because they could be too fat/obese or they could have some sort of disability that doesn't allow them to have the scan and if you have a piece of magnetic metal in you like if you've had a cut stapled together then you cant have the scan because the magnetic fields will pull it out of your skin with some skin and reopen your cut and leave you scarred for life. it will also hurt a lot if that happens!

What is an x-ray doctor called?

Radiologic technologist or Radiographer -- is the person who actually does the x-ray and acquires the resulting medical images (called Radiographs).

Radiologist -- is the person who interprets the medical images acquired by the radiographer.

What does an MRI show a doctor?

What does very heterogeneous signal mean?

I have added a link to a resource and I in answering your question

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.

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.
