MRI

my husband has t2 intense foci in the subcortical white matter in the frontal and parietal reigon these are compatible with foci of chronic ischaemic change the finding is related to small vessel disease his mood swings are getting worse would this disease be a part of mood swings.

New or used?

I have seen used machines sell for as low as $10,000. ( keep in mind this is an older machine and probably wont give you the best images compared to the latest technology) But maybe that is all that is needed for the types of scans being done at that location.

I have seen newer machines sell for as little as $250,000 to well over $2,000,000. (yes that's 2 million) Its like the options when buying a car and you pay more for newest technology. Places buying scanners evaluate what options are required for the type of scanning they do.

Almost none. There are some surgical procedures a patient may have had done, prior to having an MRI ordered, that will not allow them to have an MRI study. A pace maker would be a good example. The magnetic field can erase or reprogram the pacemaker, and depending on the material used move the pace maker or the wires in the heart.

Most modern surgical implants are safe in MRI machines, but it is safest if you make sure to let the technologist know you have had surgery in the past.

I have read some studies (forgive me I don't remember references) when I was doing MRI that stated that some people could have arm numbness when left inside a strong MRI machine for extended periods of time. This seems to effect men more so than women.

I never experienced this nor met a patient who has. The magnets are large and the biggest problem I have seen with the use of them is patients becoming claustrophobic.

The strength of the magnet is measured in teslas from 1 tesla to 3 tesla. Usually over 3 is not considered safe for humans and is only used in research.

About 20 minutes. But it dependes on what part of the body. I personally think its hard for young children to have MRI scans because you have to stay still for that whole 20 mins, but they do make you very comfortable. Its also dangerous if you wear any metal or have a metal filling or pins in your arm, but they check you beforehand for any metal. The machine makes a lot of noise so they let you listen to music or just wear headphones.

I am not quite sure what the person is wanting to know but, as an MRI technologist, I felt I might be able to shed some light on the question. MRI stands for, "magnetic resonance imaging". We use a magnetic field to image the hydrogen protons in the body that have been subjected to radio frequencies. The term resonance means that these protons are spinning at the same frequency (in sync). Patients may choose to have an OPEN MRI or a CLOSED MRI. The difference is that with a closed unit, the images are better because the magnet is stronger. It is an enclosed tube that is usually open on both ends. An OPEN MRI is usually a table with equipment above you and equipment below you (nothing on the sides). The OPEN is used to image people that are claustrophobic or that may be too large (over a weight limit) to fit inside the CLOSED unit. It is always best to discuss plans with your physician if claustrophobia is the issue. I hope this has helped.

It really depends on what the MRI is for. If it is an MRI of your leg, water generally wouldn't have any effect on that. If you are having an MRI of your GI track, then you probably should not. The best bet is to call your doctor's office or the lab that you are having the MRI done at.

None. By radiation, we're referring to ionizing radiation, or radiation with high enough energy to cause molecular damage, or possibly DNA damage. Radiation therapy, CT scan, Nuclear scans and X-rays all use ionizing radiation. MRI uses magnetic fields to induce electric currents, and employs radiofrequeny waves ( a type of electromagnetic radiation) that is not ionizing radiation. It is a form of energy, and thus metal objects, and even metal in tattoos can heat up and cause burns.

This sounds like a TIA or Transient Ischaemic Attack - what is known a "mini stroke". when a TIA is experienced it often presents with similar symptoms to a Cerebrovascular Accident (CVA - or stroke), such as weakness (usually on one side of the body), confusion, dizzy spell etc... However with a TIA, in comparison with a CVA, it usually resolves within 24 hours with no prevailing dysfunction. Be cautious though, a TIA is usually a warning sign of a possible CVA, and therefor medical help should be sourced ASAP.

No MRI is not harmful to the body of people.

To anyone who has had an MRI of the brain -- especially a CLOSED one (as opposed to the now ubiquitous open MRIs) -- the second worst thing (for most people claustrophobic feelings are the first) is the NOISE...

They typically give earphones to block out noise, and the radiologist's instructions will come through on them now and again. They usually ask you from time to time to hold your breath for a moment, to be sure your head is absolutely still.

They may pipe music in through the 'phones, but let me tell you, once that thing gets going, you won't hear any music. Not even if you're listening to heavy metal.

All you will hear is:

"Rrrrrrrrrrrrrrr -- WHAMMMM!! Ka-CHUNG Ka-CHUNG Ka-CHUNG Ka-CHUNG Ka-CHUNG Ka-CHUNG Ka-CHUNG Ka-CHUNG...." at a decibel level that you will be quite sure is equal to the noise of an old Concorde -- or possibly a new space-shuttle -- taking off from your backyard.

It goes on and on and ON and ON AND ON until you start thinking you're going to totally lose it, and you have to wonder if this feeling is going to have some influence over what your brain looks like to the machine. Relax; it doesn't. If it were a PET scan, that'd be different. (And less noisy anyway!)

Yes it can. This is because fMRI technology can be used to create images of oxygen use in various brain areas. It can be assumed that when an area is active, it consumes oxygen. Therefore, fMRI can identify whether or not a region is active or not during a process when it should be according to the norm.

For me, it took about five days. Though my doctor told me it could be anywhere from three days to two weeks. For me, it took about five days. Though my doctor told me it could be anywhere from three days to two weeks.

This is controversial as bullets can deflect and move in conventional 1.5T scanners. Research the various literature yourself at the NLM pubmed site (google it). There are reports of bullets migrating within the spinal canal, and reports of no adverse sequela to the patient with bullets in their canals undergoing mri with complete paralysis. Bullets near vessels are dangerous, as fragments can theoretically cause vascular injury (bleed!). In general, most radiologists favor not putting patients at risk when bullets are near the spinal cord or major blood vessels. There are always exceptional cases, dealt with on a case-by-case basis.

Usually around 35.00 to 40.00 per hour. Wages are about 10% higher if you work in a private imaging center than if you work at a hospital. Wages are also 10-25% higher if you have a Bachelors Degree in Diagnostic Imaging. MRI, Nuke Med, Radiation Therapy, and Ultrasound all pay around the same but vary between location and employers, but CT Techs usually make about 5.00 an hour less than the others and rad-techs about 15.00 an hour less than the others.

In order to create clear and effective imaging of soft tissue with a high level of detail and precision, with minimal radiological harm to the patient.

my grandpa had that done.he said its a simple thing to have done.what they will do is haveyou put earplugs in and tape your ears and depending on what part they are looking at is how far you will go inthemachine.like if its your head they are looking at you will go in the machine up to your chest.they give you a button to push if you get nervous.the machine makes loud noises and you have tostay still the whole time.thats all it is.

i think radio if not x rays but im pretty sure its radio

When you're told that an MRI is "not remarkable" or "unremarkable" it usually means that they didn't find anything within the result. Where as if you were told it was "remarkable" it typically means that they found something in the area where they were looking.

it sort of looks like a giant polo but if you go on Google images it has lots of pictures of MRIs

mobiles,laptops,cars,computers,artificail intelligence

Magnetic resonance imaging (MRI), nuclear magnetic resonance imaging (NMRI), or magnetic resonance tomography (MRT) is amedical imaging technique used in radiology to visualize internal structures of the body in detail. MRI makes use of the property of nuclear magnetic resonance(NMR) to image nuclei of atoms inside the body. MRI can create more detailed images of the human body than are possible with X-rays.
