MRI

Only if they are still semi-liquid in the middle.

If they are ( maybe 1% are ) then the filling, and so the tooth, will burst - very painful.

However, 99 times out of 100 it's fine

If contrast is going to be usedduring the MRI, kidney function must be adequate to filter the contrast. If they are compromised the contrast can cause a serious disease.

My perspective is that M.R.I is is good probably because it's used for x-raying your brain to see if there are any tumors or anything bad that is going on to your head. I think M.R.Is can't see wood, they can't see it through its scanner. I don't know why but it just can't.

MRI exams can be done:

1. Without contrast (dye) 2. With contrast (dye) 3. With and without contrast (dye)

The majority of MRI exams are done without contrast. Most common reasons for contrast administration include infection, cancer, and after surgery.

FDA approved contrast agents are gadolinium based and are safe to use in patients. However, they can have very harmful side effects if the patient develops an allergic reaction or has kidney disease or kidney failure. Without functional kidneys, the body cannot get rid of the gadolinium from the contrast agent, which can cause a deadly and incurable disease known as nephrogenic systemic fibrosis.

Its a bit like comparing apples and pears! Older instruments are closed some could only take patients upto 140kg and not many were big enough to allow most head restraints used by surgeons. Open imagers were designed to make the experience less clostrophobic and allow larger object to be placed inside.

If you were performing the same tests then the time difference is probably non-existant for a modern open and a modern closed instrument. However, you are probably comparing an old closed instrument with a modern open instrument - the open is quicker. However, if the hospital has been diligent enough to buy a modern instrument perhaps they would like to run more tests whilst you are in the MRI scanner. Each test is run separetly and so running more tests with the instrument in different modes will take longer. Your radiographer will be able to tell you exactly how long the scan will take.

Summary - Open instruments tend to be more modern than closed instruments. Open instruments are more plesant to be scanned in. The number of modes of scan performed it the critical factor in how long the scan takes.

Yes, it's true.

The ventricular system is a set of structures containing cerebrospinal fluid in the brain. It is continuous with the central canal of the spinal cord. If it is dilated, that means it is enlarged. The causes need to be explained by your physician.

CAT scans and MRI scans are useful for a wide variety of medical investigations; the MRI in particular is very useful for neurological examinations, since it is otherwise very difficult to examine the brain in any detail. CAT scans can be used for all sorts of things, to investigate illness or injury in any part of the body. I had one recently for a kidney stone.

You can easily call the place where you're having it done and ask beforehand. Before that, I recommend you take a pharmacy bough pregnancy test to know if that's even an issue.

I can find nothing that supports evidence that an MRI can cause harm such as cancer. believe me I am looking. But I still feel reluctant to have one. I have already had three MRI's of my brain.

The agency that referred the patient for the MRI; the doctor or clinic.

Yes.

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.

Simply? No.

Wearing a wire bra during an MRI scan would affect the image quality around the area where the wire is e.g. the thoracic spine or the breast. It might also feel a little strange as the wire in the bra would potentially be twisted or moved by the magnetic field.

It is possible to listen to music during an MRI. The person being scanned wears headphones during the scan, enabling the technicians to communicate with the person being scanned. Generally you can take a CD, sometimes they have their own selection, but that could be risky! The technician will put the CD on for you and it will play through the headphones.

MRI stands for Magnetic Resonance Imaging. It's a nuclear process that allows doctors to see beneath flesh to identify damaged ligaments and tendons.

Dr. Lauderber came up with the concept of using graduated gradient magnetic fields on top of the primary static magnetic field to assign data to a specific place. The gradients slightly change the magnetic field in 3 planes.

Lesion is a nonspecific term that means any abnormality in tissue. If you didn't have an abnormality, you wouldn't be scheduling surgery. Talk with your orthopedist for information about your examination results.

Arachnoiditis is inflammation of the the leptomeninges (arachnoid and pia mater). These structures wrap the surface of the brain and spinal cord. When they are inflamed, whatever the underlying cause, gadolinium injection during an MRI scan causes enhancement of the leptomeninges on T1 weighted images.

Many different health problems may cause arachnoiditis (from tuberculosis to carcinomatosis to autoimmune diseases).

So, strictly speaking, arachnoiditis on an MRI means the leptomeninges enhance.

3T MRI scans are scans done using twice the magnetic field strength. This is a physical difference. The stronger magnet allows us to see more information in the same time. So a 3T scan is simply twice as good, at least 4 times as fast and also delivers more radiofrequency RF energy during the scan. This means it sometimes feels warm inside the scanner. But to most patients this is a unimportant difference.

The true difference is the increased diagnostic capability of 3T MRI. For instance breast lesions are seen 100% at 3T but only 90% at 1.5T. In the case of MS we usually see 37% more lesions in the same patient with the same scans. However - we can sometimes see up to 300% more lesions. In my experience 3T MRI is superior to 1.5T MRI in most cases. We us 1.5T OPEN BORE MRI for our larger patients and claustrophobic patients but in most patients we find that 3T is superior to 1.5T.

We offer both to our patients and are one of the few facilities in the world that allows the patient to choose.

An MRI with contrast is a high-tech medical imaging test that can help your doctor diagnose many different types of diseases. One would require an MRI with contrast if one had a history of tumors, cancers or surgeries.

It depends on the scan, and your age. For an fMRI or Functional MRI exam, the patient is asked to perform a wide variety of tasks, like playing games. If a child is to be scanned, they are usually sedated, so therefore cannot play any games whatsoever.
