How long does the magnetic resonance imaging take?

How long does the magnetic resonance imaging take?

Depends: Length of an MRI study depends on what area (s) of the body is/are being imaged, whether the study is done without & with contrast, whether any complications occur during the study (some people get very nauseated from contrast rapidly infused), whether you move during the study, how comfortable you are lying very still for several minutes, if there are unexpected reactions to the contrast. ...Read more

What are the pros and cons of magnetic resonance imaging?

What are the pros and cons of magnetic resonance imaging?

Best for soft tissu: Pro: you can see soft tissue better, some things, just can't see with ct especially useful in brain, spine, liver, any joint disorder. Uses no ionizing radiation (xrays).
Con: cannot have if certain implants, i.e. Pacemaker, defribillitators, aneurysm clips, metal in eye etc. Also prob with claustrophobia, ct better for arteries, veins, except mra of head, for specific conditions. ...Read more

Can a magnetic resonance imaging test have any bad effects on bady, if so, what could be such effects?

Can a magnetic resonance imaging test have any bad effects on bady, if so, what could be such effects?

None proven: Though many people have claimed side effects ranging from tingling to fatigue to a change in hair color, there are no proven side effects of mris. Never the less, effects on the fetus of a pregnant woman are unknown. People with some implanted electric devices such as pacemakers may not have mris. ...Read more

Mri (magnetic resonance imaging) used to be called nmr. Was the change political?

Yes: College of radiology was afraid the word nuclear in NMR would scare people away. Know what else MRI stands for? ...Read more

Can magnetic resonance imaging be done on persons with metal implants in their body?

Can magnetic resonance imaging be done on persons with metal implants in their body?

It depends: Mri scans place the body in a magnetic field. A metal fragment in the eye may move and create damage to the eye. A hip or knee prosthesis is unlikley to be affected but may create imaging problems because they will distort the magnetic field and the image created. ...Read more

What are advantages of MRT (Magnetic Resonance Tomography) scan over MRI (Magnetic Resonance Imaging) scan? Are these equally safe?

Same: Those are equivalent terms for the same type of imaging. No x-rays or iodine containing contrast is used for MRI studies.

Here is a helpful link.

Mri (magnetic resonance imaging) ok if stainless steel plate in arm?

Yes, but..: A stainless steel plate for fracture repair will affect imaging of that specific area. Some people can have sensations when getting the exam but most don't. Effects may be more significant on the stronger
3t magnets but most people notice little to nothing. ...Read more

Can a person keep his dentures (fixed) on while going for MRI (magnetic resonance imaging)?

Yes: If your denture contains no metals, there should not be a problem. Ferromagnetic items pose problems for mris. A full denture does not normally have metal within it. Some full dentures have metal re-enforcement and should be removed. Most partial dentures also have metal clasps or frameworks and should be removed. All metals can distort MRI images and should be removed. ...Read more

Can a high-powered magnetic resonance imaging scanner cause cancer to patients or staff?

Can a high-powered magnetic resonance imaging scanner cause cancer to patients or staff?

No known association: Mri relies on changing nuclear atomic spin, and does not change the chemical bonds of molecules, which can alter dna and cause cancer. However, the use of a contrast agent in patients called gadolinium during the procedure may induce the onset of a debilitating malady commonly known as nsf/nfd. This can cause fibrosing throughout the body. Http://www. Medscape. Com/viewarticle/550783. ...Read more

What is nuclear magnetic resonance spectroscopy?

MRS or MRI: MRI is magnetic resonance imaging a type of medical imaging
MRS is MR spectroscopy a rarer medical type of exam based on the science behind MRIs in part aimed at either parts of the brain or perhaps skeletal muscle to evaluate metabolism at times....both would be done in an MRI facility. When developed the nuclear part of both was dropped so as to not scare people about it.... ...Read more

Does it hurt to get a magnetic resonance cholangiopancreatography done?

Does it hurt to get a magnetic resonance cholangiopancreatography done?

Nope!: Mrcp is extremely safe and completely non-invasive. You usually don't even need to have contrast injected. You will essentially be slid into a tunnel (the MRI machine) which will whir and make loud noises but you will not feel anything. If you have claustrophobia, you may want to ask your physician for some anti-anxiety medications to take just before the mri. ...Read more

Mri (Definition)

Mri or magnetic resonance imaging is one of the more recently developed imaging modalities available to physicians. It uses powerful magnets to generate images. There is no ionizing radiation which is a major advantage over many other modalities. Mri is the best imaging exam that we have for most soft tissue and joint related problems. There are radiologists ...Read more
