MRI

MRI stands for magnetic resonance imaging. It is a particularly useful scan for neurology, cardiology and oncology patients. Questions on how they work, their development and uses can go in this category.

What is an arthrogram?

An arthrogram is a series of images, often X-rays, of a joint after injection of a contrast medium.

Is it safe to have another MRI after six months?

MRI Magnetic Resonance Imaging.

An MRI does not use dangerous radiation like an X-ray does. It is just a powerful magnetic field that (so far) hasn't been associated with any deliberating effect.

What is a Telemetry Monitor Technician?

someone who reads heart monitor strips and by measurements determaines what electrical rhythm the heart is in

Is it safe to have an MRI with internal abdominal staples of unknown metal applied in 1975?

nope i dont think it would be safe however long they've been inside you however ask. i knew someone who even had to take off an underwired bra so i doubt you'd be able to. it is obviously highly sensitive to any kind of metal

What do MRI results mean when they say level C6-C7 demonstrates a small central disc protrusion associated with?

That means there is a bulging disc that is impinging on the central canal (spinal cord) between the vertebral bodies at the C6-C7 levels, which may or may not be symptomatic.

What are the applications of 2D and 3D scanners?

There are a number of applications that require the use of of 2D and 3D scanner. These include CT scans, MRI scans, and simply for printing out 3D models for experiments.

Is it better to have arthroscope or MRI?

Well, an arthroscopy is an invasive procedure. They actually look into whatever joint you need examined. On the other hand, an MRI is exactly that, an image or picture of the joint in question. So the option is totally yours...minor surgical procedure or...a picture, you pick.

What rays are given off with an MRI?

An MRI scanner emits radio waves whilst it is scanning and utilises a strong magnetic field. It does not emit any ionising radiation like X-rays.

Why are MRI scans not allowed for six months after coronary stenting?

The patient should not have any magnetic resonance imaging (MRI) tests for six months after the procedure, because the magnetic field may move the stent.

Where do they inject the contrast agent for an MRI of the lumbar?

The contrast agent will be injected into the spinal canal between the disc nearest to the area to be examined - you'll need to ask your doctor or the technician for a more precise answer . (For me , it was uncomfortable but not any more painful than getting a shot .)

I am a women in my 30's and I have been diagnosed with a non displaced tear in the posterior horn and body of medial meniscus in MRI scan Is it necessary to undergo surgery Could it heal by itself?

Unfortunately, damaged cartilege can't heal by itself as it has no blood supply.  The joint may settle down with anti inflammatory medication and ultrasound treatment from a physiotherapist, but this approach rarely works well.  The only real option is surgery, frankly.  These days this operation would be done by keyhole surgery.

Is there raideaction in a mri?

If you mean "radiation" then the answer is yes. Electromagnetic radiation in the radiofrequency spectrum. Note that this differs from x rays in that it is not damaging to the tissues.

Who runs the mri machines?

The technologist. A radiologist reads the study later.

If patient undergoes MRI and has titanium hip if wallet is placed in pocket of the replaced hip after MRI can credit cards be erased?

Whether they have a new hip or not, you are putting a magnetic strip into an incredibly strong magnetic field. The MRI should be enough to wipe or corrupt the data in the strip.

What does it mean if your lumbar MRI results show negative?

It means that they could find nothing wrong on the MRI.

What does the bone marrow signal intensity of the vertebrae is unremarkable on a cervical MRI mean?

It means that everything is the way it should be in your cervical spine. Nothing is wrong.

MRI showed small effusion in knee what does this mean?

A small amount of fluid build up at the joint, possilby a sign of slight arthritis, mild gout or a moderate physical trauma ( for example a fall onto the knee).

Your cervical spine MRI showed a bulge in the C6-7 disk What does mean?

The human spine is separated into several sections - Cervical means the neck vertebrae. The C6-7 disk is between the C6 and C7 (Cervical) vertebrae.

Depending on the severity of the problem (whether or not the disk is just bulging or has in fact ruptured through the disk membrane (herniated), the problem can be corrected either with facet injections or other non-invasive therapy. However, if the problem is severe enough, it will begin to affect one of your arms (usually the left) to the point where paralysis may set in if it is not corrected.

Staying clear of anything that can potentially aggravate this cannot be overstated. If you further damage the disk to the point where it cannot be dealt with by steroidal injection, NSAID's and bedrest, surgery is the only other option. While the procedure has gotten a lot easier since I had mine done in '96 (my surgery was a fusion of the C5/6/7 vertebrae - those disks had collapsed), it is still major surgery, and you can expect at least 3-5 months to recover, more if they require a bone graft from the pelvic area (never opt for cadaver bone as it has been proven it can transmit the AIDS virus).

Do whatever therapy your doctor tells you - it is not something to be taken lightly, and if the disk is in fact herniated, there will always be a weak spot in the disk membrane. What that means is that you'll always be at risk of another herniation at that spot, even if it heals, because it will always be weak.

What if your husband is 75 and has had an mri scan datscan and eeg its has found poor cerabal circulation what could this indicate?

That kind of question can only be answered by a doctor who has seen the scan and is familiar with other aspects of the person's health.

What do the MRI results mean advanced chronic changes?

The words advanced chronic changes in MRI results mean that there is some sort of chronic condition which has been present for long enough for the damage to be advanced. An example of this would be the changes which can be seen with advanced pancreatitis.

What is the full form of CATand MRI?
