MRI is Magnetic Resonance Imaging and uses a big magnet rather than xrays to see the differences in tissues inside you. One magnet 'lines up' all the electrons in your body (doen't worry it doesn't hurt!) then another magnet is applied at 90 degrees to the other for a little bit and the machine measures the different electron movements - each type of tissue will be different.\nMuch better at looking at soft tissues (spinal cord, ligaments.etc..) than CT scans.\nYou mustn't have one if you have any metalwork in your body like clips on your brain or a metal foreign body in your eye.

An open MRI is a good idea. Even with an open MRI, you will find a brain scan can be hard to get through.  The coil (camera) needed for a brain scan can feel very claustrophobic to many people, so medications to relax you might still be needed.   Also, bring a friend/family member who can go into the scan room with you.  Just make sure that person hasn't had a pacemaker, aneurysm clips in the brain etc.  Many of my patients have their spouses read to them during the scan.  Call ahead and ask if the facility can pipe music in the room via a CD or a tape, so you can bring your favorite music.  And try to remember that a MRI will give your doctor very valuable information which can change your treatment, and make your life more comfortable!

It is a system of measurement used to characterize the relative density of a substance X-rayed. Helps radiologist distinguish between air, fat, water, soft tissues, bones etc. on CT scans for example.

Progressive scan allows for a better quality picture when viewing media from a source that support it as well.\n\nfor example, if you DVD player support progressive scan, your TV must also support it inorder to use the function.

It sounds like you need to see an Orthopedic Doctor who will probably recommend Physical Therapy (which helps most people).  Your problem sounds like a herniated disc which can be helped with PT and medicine.  Bengay also helps for some immediate relief.  If the Doctor who ordered the MRI was an Orthopedic Doctor, get a second opinion.\n\nhttp://www.spine-health.com/topics/cd/d_difference/diff01.html\n\nhttp://www.medicinenet.com/low_back_pain/article.htm

Hey, getting an MRI is appropriate...then again the doctor may have to be able to read it correctly. I did have an MRI, one doctor said that I needed surgery, another told me that I need not. So I decided to be conservative and did physiotherapy, wore a brace for sports and it took me almost a year to recover fully. Healing takes time...give it the time that it needs...and it will! God bless U.

An xray will not show muscle, only bones and some soft tissue. \nAn MRI will show muscles.

I am a MRI technologist who is in direct contact with the magnet on a daily basis.  I have 9 piercings in my ear, a tongue ring, a nipple ring and a belly ring.  I have never had the magnet rip out any piercings.  As a patient, if I were going to be scanning your head, I would ask that you remove any piercings in that direct area.  They can cause an artifact on your images.  If I were doing a MRI on your hand, I would ask you remove any rings or bracelets.  You should always remove watches for any exam as the magnet will break the watch.\n\nHere is what I found:\n\n"Jewelry: Xrays, MRIs, and CT Scans\n• Metal body jewelry will result in an opaque density on x-rays, but will not otherwise affect visibility on film\n• Nipple piercings are unlikely to obstruct visibility of any pathology on thoracic x-rays if both frontal and lateral views are taken\n•** Appropriate body jewelry is non-magnetic, and as such does not need to be removed for MRI procedures* unless it is located in the region being examined\n\nhttp://www.safepiercing.org/troubleshooting.html\n\n"Appropriate metal body jewelry is not magnetic, and as such does not need to be removed for MRI procedures unless it is located in the region being examined. Gold jewelry is much more thermal-conductive than steel."\n\nhttp://www.navel-rings.net/troubleshooting.html

MRI, magnetic resonance imaging, has been used quite extensively recently to explore the function of the brain.

Nuclear medicine involves the use of radioactive isotopes to create images of the body/interior of the body.  These images are used to diagnose certain problems and conditions.\nExamples of the tests used in nuclear medicine are the MRI, computerized tomography, and PET scans.  \n\nFor more information see article here:\nhttp://en.wikipedia.org/wiki/Nuclear_medicine\n\nHere is a Dept. of Labor information sheet on nuclear medicine techs:\nhttp://www.bls.gov/oco/ocos104.htm

My younger sister has one in her arm and has had it for over 20 years, she is 28.  If i remember correctly they inject a dye in your body and then do the scan, the reason the whole body is done, is once you have one you may be more susceptible to more and the dye will show any more that are developed.

Well, there are CAT Scans where they take pictures of the brain in "slices" and there's an MRI, similar but much more detailed.  CAT Scans are used before MRI's because they are cheaper and Insurance companies insist on it.  And these are the only two ways to do it without cutting the top of your skull off.  I'm not trying to be funny, just stating a fact.

depends on the area - most dr visits run about 100.00.  The MRI on the other hand is very expensive - about 5000.00.
