What is T2 signal in MRI?

The T2 signal is used by MRI machines to help identify different characteristics of tissues within the brain. For example, the T2 signal can help identify if the tissue contains too much water.

How would spinal cancer show on an MRI?

An MRI may show brain changes in a patient that has bacterial meningitis. However, the diagnosis is not given based on images alone.

What does it mean when a MRI states unremarkable?

There was nothing found that was out of the ordinary. There was nothing that was not expected to be found.

Can someone with an artificial hip replacement have a mri?

Most contemporary orthopedic implants are made of non-magnetic metals, so there is little danger to these patients in terms of magnetic attraction. It is always critical to positively identify each and every implant and device within your body, however, before receiving an MRI.

Even non-magnetic metals do interact with the magnetic field of the MRI and may distort or disrupt the image that the MRI captures in the vicinity of the implant. A non-ferromagnetic hip replacement may not have any significant effect on an MRI of your ankle or head, but may impair your ability to have a successful scan for, as an example, a prostate.

What do MRI results mean if they say S1 L5 moderate disk bulge is present?

your disc between your lowest lumbar vertebra and your sacrum is inflamed and swelling out of where it belongs. it's a lot better than a protrusion or herniation so you're not in too bad of shape. use ice, ibuprofen, and take it easy.

Difference between NMR spectroscopy and MRI?

Nuclear Magnetic Resonance Spectrometry (NMR) is the term used in the sciences, e.g. in probing chemical structures, however the term "nuclear" is toxic to some people and the medical profession dropped the term and use Magnetic Resonance Imaging (MRI) or MR when NMR is used to study the structure of organs in the body. The same physical priciples apply

What are the side effects of an mri with contrast?

MRI contrast agents do not usually cause side effects. Rarely, they can cause Allergies (mostly skin rash), nausea. When used in large quantities, they sometimes cause renal failure, but usually not on healthy kidneys.

I have degenerated disks in my neck a frozen shoulder from a blood test injury and pinched necknerves.also whole head and face and jaw pain . mri was negative on brain scan.is head pain from neck?

I'm not exactly sure what a blood test injury means; do you mean infection from a blood test? Otherwise a disc or discs that are degenerated or bulging can cause a number of symptoms including head, face, or even arm pain.

Without looking at your mri I could not really tell you exactly. What was it negative for? I'm assuming they've ruled out anything major like fracture, tumor etc...But if you have disc degeneration that will show up.

I would use a good neck pillow for the neck, it most likely will improve alot of you symptoms. Use ice and/or heat olong with tens to the shoulder to help that recover quicker.

Who can tell you what essentially normal means for a brain scan?

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?

My 9 year old granddaughter has been disgnosed with AC1M, and we have alot of family members with brian problems, like cysts and hydrocephalus etc. And now the 9 year old has got a hydromyelia on her spine.

Just need some answers to see where this all came from...l certainly have a lot of sypmtoms for years, without knowing about the condition.

Can anyone answer my question, l wuld be most grateful.

Thanks so much from Chriskeykey

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 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.
