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 are the health hazards of MRI scan?
MRI scans are one of the safest type of scan in modern medicine. The detailed results it gives without the danger of radiation is remarkable. There is one well known hazard however, that is that any metal in a persons body will damage the body due to the magnetic aspects of the MRI.
What does it mean to have white spots show in a mri results?
I've been researching a little and one white spot might be one attack of the immune system, single scelorosis. this is a possibility. it can mean so many other things. more than one spot might mean multiple sclerosis.
What is mri internal auditory meatus both?
An MRI (magnetic resonance imaging) is a tool used to examine internal body structures. An MRI of the internal auditory meatus is an MRI scan used to look for a problem with the nerves supplying the inner ear.
When is the mri scanner used and to see what?
Dr. Raymond Damadian, a physician and scientist, toiled for years trying to produce a machine that could noninvasively scan the body with the use of magnets. Along with some graduate students, he constructed a superconducting magnet and fashioned a coil of antenna wires. Since no one wanted to be the first one in this contraption, Damadian volunteered to be the first patient.
When he climbed in, however, nothing happened. Damadian was looking at years wasted on a failed invention, but one of his colleagues bravely suggested that he might be too big for the machine. A svelte graduate student volunteered to give it a try, and on July 3, 1977, the first MRI exam was performed on a human being. It took almost five hours to produce one image, and that original machine, named the "Indomitable," is now owned by the Smithsonian Institution.

CT Scan is the short form of Computed Tomography, also known as CAT scans. In this technique, the patients are exposed to higher radiation levels compared to most of other imaging techniques.
CT Scan technology involves the use of an X-ray generating device that rotates around the patient's body. These powerful beams are picked up by an array of detectors and used by a computer to generate a three-dimensional view of a body region.
Experts agree that when used correctly, such scans can save lives. However, according to some estimates, the radiation exposure a patient receives from a full-body CT scan is often 500 times that of a conventional X-ray and about the same as that received by people living 2.4 kilometres away from the centres of the World War II atomic blasts in Japan.

What are the best MRI technician schools?
In order to obtain a job as an MRI tech, it is best to get an associates degree in radiologic technology. This will help you have an understanding for how the technology works. There are also certificates you can obtain that you have the ability to operate an MRI machine.
How much does it cost to have an MRI of your brain?
about 800 in the caribbeqn and 1800 in the united state
What neurological disorders can be diagnosed by the mri?
Lots! Most abnormalities of the brain can be seen on MRI better than on a CAT scan e.g. brain tumours, multiple sclerosis, Parkinson's, blood clots and lesions. Neuro science is a complex area with numerous diseases and the MRI has greatly assisted in diagnosing neurological conditions.
When was the first mri scan done?
i was, honestly, it doesnt hurt. just shocking orcoucre becasue of what i was going through. my name is Sophie perkins and is there anythoing you woulkd like to ask me about it. i'llbe happy to help you.
What does abnormal bone marrow signal mean?
When an mri shows abnormal bone marrow signals in the hip, there could be a number of causes. The causes vary based on whether the abnormality is in the red or yellow marrow. You will need to consult a physician to discuss the possible reasons for the abnormality.
The ommaya Reservoir is safe to a 1.5Tesla-strength scanner. That is the most common scanner in most facilities, though 3Tesla+ are becoming more prevalent.

What do the initials MRI stand for or mean?
The meaning I know is 'Magnetic Resonance Imaging', though there will be others
How much does mri machines cost?
The cost of a 1.5 T MRI machine ranges from $1 million and $3 million USD depending on the model. These machines are designed for use in hospitals for advanced medical diagnostics.
The T2 signal is used by MRI machines to help identify different characteristics of tissues within the brain. For example, the T2 signal can help identify if the tissue contains too much water.
How would spinal cancer show on an MRI?
An MRI may show brain changes in a patient that has bacterial meningitis. However, the diagnosis is not given based on images alone.
What does it mean when a MRI states unremarkable?
There was nothing found that was out of the ordinary. There was nothing that was not expected to be found.
Can someone with an artificial hip replacement have a mri?
Most contemporary orthopedic implants are made of non-magnetic metals, so there is little danger to these patients in terms of magnetic attraction. It is always critical to positively identify each and every implant and device within your body, however, before receiving an MRI.
Even non-magnetic metals do interact with the magnetic field of the MRI and may distort or disrupt the image that the MRI captures in the vicinity of the implant. A non-ferromagnetic hip replacement may not have any significant effect on an MRI of your ankle or head, but may impair your ability to have a successful scan for, as an example, a prostate.
What do MRI results mean if they say S1 L5 moderate disk bulge is present?
your disc between your lowest lumbar vertebra and your sacrum is inflamed and swelling out of where it belongs. it's a lot better than a protrusion or herniation so you're not in too bad of shape. use ice, ibuprofen, and take it easy.
Difference between NMR spectroscopy and MRI?
Nuclear Magnetic Resonance Spectrometry (NMR) is the term used in the sciences, e.g. in probing chemical structures, however the term "nuclear" is toxic to some people and the medical profession dropped the term and use Magnetic Resonance Imaging (MRI) or MR when NMR is used to study the structure of organs in the body. The same physical priciples apply
What are the side effects of an mri with contrast?
MRI contrast agents do not usually cause side effects. Rarely, they can cause Allergies (mostly skin rash), nausea. When used in large quantities, they sometimes cause renal failure, but usually not on healthy kidneys.
I'm not exactly sure what a blood test injury means; do you mean infection from a blood test? Otherwise a disc or discs that are degenerated or bulging can cause a number of symptoms including head, face, or even arm pain.
Without looking at your mri I could not really tell you exactly. What was it negative for? I'm assuming they've ruled out anything major like fracture, tumor etc...But if you have disc degeneration that will show up.
I would use a good neck pillow for the neck, it most likely will improve alot of you symptoms. Use ice and/or heat olong with tens to the shoulder to help that recover quicker.
