However much the engineers who designed it designed it to use. This may be different in different parts of the scanner, or even in different models of the scanner depending on where it's intended to be used (the US, Europe, Canada, etc.).

There's no theoretical reason it couldn't accept whatever is the typical mains voltage in the area and convert it internally to whatever is needed. For example, the computer part is probably running on a mix of 5 and 12 volts, while the coils are likely whatever they can shove through there without actually melting something.

MRI uses high magnetic fields and radio frequency and not x-ray. The procedure is generally safe and typically repeated examinations do not cause any problems.

However, some MRI scans use a Gadolinium-based contrast agent, so repeating MRI scans within a few days may expose a patient to higher-than-expected levels of the contrast agent in the blood, which can be affected by kidney function. Patients should check with their doctor before having a repeat contrast MRI scan within a few days.

There is no pain involved in the MRI. The venous access to inject gadolinium involves a intravenous catheter.

im not to sure but they have contacted me also...

with a contract and promises of payments. has there been any progress on this question? or perhaps who might we be able to contact about said issue?

When interpreting an imaging study (xray, CT, ultrasound, or MRI, among others), sometimes a particular finding can mean different things in different clinical situations. When a radiologist comes across a finding which may mean multiple things, a radiologist says "please correlate with clinical findings" or "clinical correlation requested" to indicate the finding may mean several things in different circumstances.

For example, on a chest Xray there may be some opacities in a lung field. That, combined with the clinical information that the patient has a high fever, with yellow sputum, high white blood cell count, and is a young woman without other medical problems--then the leading suspicion is that it is an infection, likely pneumonia. On the other hand, if the clinical information is that the patient has just had minor surgery, no fever, has some shallow breaths, then it's more likely that the opacities can be due to atelectasis.

As we know,Clarity of the image is decided by its Spatial Resolution but not by Pixel Resolution.

CT have high Spatial Resolution but MRI have comparable Spatial Resolution to CT&far better Contrast Resolution than CT-So,MRI is the BEST to demonstrate Anatomy,especially in parts containing more soft tissue[Eg:Brain]&CT is the BEST to demonstrate Bony Anatomy.

With an MRI or any other assessment, a false negative is when the test says nothing of concern is present when something actually is. In other words, when a test fails to detect something that is actually present. A false positive is when the test says something is there but actually it is not there.

my husband has just had an apendicitis. In the CT scan it was found (incidental finding) two hypodense focal massess in the neck of the pancreas that will require follow up (MRI). We are freaking out. What could that mean? is it smething seriois or somethig normal? Thanks

MRI stands for "magnetic resonance imaging." An MRI is used in the medical field and provides a strong contrast of soft tissues that most medical equipment like a CT or X-ray cannot provide. A strong and expensive magnet is used to scan the body's healthy and diseased tissue. These machines may cost in the millions and will have varied strengths depending on the medical need for the scan.

MRI stands for Magnetic Resonance Imaging. It is a device used to visualize internal structures of the body in detail. It is especially useful in measuring the brain, muscles, the heart and cancers. This is due to the fact that it provides good contrast between soft tissues.

"What could "fluid shown in fallopian tube" on MRI mean? Your doctor will most likely recommend a follow-up and probably a pelvic ultrasound. There are a few different things that could cause this; and it's important that you follow your physicians advise. Could be caused from previous surgery, endometriosis, etc.

Yes, it can... May depend on just how long you've been having the pain... Physical exam is probably the best way to make the diagnosis... A fair screening test is to lie on your side on a firtm surface and have someone smash down [heavily] on your hip... or lie on your back, place one leg over the other [like crossing your legs] and have someone press down on your knee... this will put stress on the SI joint on that side of your body, resulting in a lot of pain [that's IF you have sacroiliitis on that side of your hip]...

I have scoliosis(curvature of the spine)so I have had to have a countless # of MRIs.MRIs are extremely loud and unpleasant.Sometimes you have to have an IV put into your arm,but most of the time you don't.After laying down on the machine's bed it raises a couple feet and slowly goes into the machine.Once it goes inside,you have to stay COMPLETELY still.The entire process can take anywhere from 1 minute to 2 hours so they give you a squeeze ball that you squeeze if you need to take a bathroom break or just get some air.

The plane of acquisition in BLADE is rotating, vs. a standard FLAIR has a single direction plane of acquisition (e.g. axial or sag). For BLADE, picture a plane rotating on a point like a see-saw, but 360 degrees. BLADE has been demonstrated to correct better for motion and Gibbs artifacts. See Wintersperger et al, 2006 in Investigative Radiology.

MRI is Magnetic Resonance Imaging and a CAT is a computerized X Ray (Computer Assisted Tomography)

MRI will work fine in case of diagnosis of soft tissues and CT will work fine for bony structures and inner ear analysis.

Also MRI do not use any radiation it is based on magnetic effect so less side effects compared to CT which uses X- rays.

MRI is very much costlier compared to CT.

MRI is problematic in case if the patient is having some metallic implant, which will cause interference with the magnetic field.

In order to determine any hairline crack then MRI would be preferred compared to CT.

High quality metal isnt magnetic so it shouldn't interfere. However, the medical professionals have no way of knowing if yours are good quality or not so they'll probably make you remove them:)

Functional MRI is an MRI procedure to determine activation in the brain during activities or in disease condition. Also known as fMRI. fMRI uses the same MRI machine as other examinations but it requires special additional software. Detection of activation in the brain is determined by the oxygen content in the blood vessel under the premise that oxygen level is high when the brain is activated.

OCC stands for Office of the Comptroller of the Currency and it is a bureau of the US Treasury department and is the federal banking regulator.

MRA stands for Matters Requiring Attention, and is the way that the OCC communicates to the banks a need for an action item to be addressed. These MRAs tend to be taken seriously by the banks.
