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 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

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

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

Is the magnetic resonance cholangiopancreatography a risky thing to do?

No: Mrcp is a safe procedure that involves exposure to a powerful magnetic field, . As long as you do not a heart pacemaker, aneurysm surgical clips in the brain, spinal stimulator devices, or any other reason why going into a MRI machine is unsafe for you, then you will be safe. ...Read more

What is the definition or description of: magnetic resonance angiography?

What is the definition or description of: magnetic resonance angiography?

Blood vessel imaging: The most simple description is: an MRI study that has been adjusted to specifically look at the anatomy associated with or involving the major blood vessels of the body. This usually involves a contrast agent (dye) that is injected during the study and a very specific protocol for the MRI (program). It gives the radiologist a lot more information regarding the blood vessels than a regular mri. ...Read more

I took a quantum magnetic resonance test. Most of my results are very good except for serious lysine deficiency. How legitimate is this test?

I took a quantum magnetic resonance test. Most of my results are very good except for serious lysine deficiency. How legitimate is this test?

No way to tell: These machines, the majority made in china, are used predominantly by beauty clinics, diet centers, and other such non-medical operations. Unaware that these values are used by any reputable medical facility as a screening device. Find it highly improbable that you have an isolated deficiency in lysine, but you might check with a general internist in your area. ...Read more

Are magnetic resonance angiogram and venogram usually performed with the posterior view or anterior? Does it depend on symptoms and site of symptoms?

Cross sections of: Body which are reconstructed in software to show any of multiple views, depending on machine, software, technician & radiologist chosen protocols. Symptoms & site of symptoms are not a driving factor in how the scan is performed. These issues are dictated by body anatomy & the construction of the scanning hardware. ...Read more

Can magnetic resonance neurography detect injury/inflammation to the ilioinguinal nerve or the iliohypogastric nerve? If not, what can?

It may: Mr neurography has not been perfected, is only performed at a few specialized centers, and highly operator dependent. High resolution ultrasound may be more cost effective and provide the desired information. Regardless, injury to these nerves can be diagnosed on clinical grounds and imaging is rarely needed. Diagnostic nerve block with an anesthetic agent may help confirm the diagnosis. ...Read more

Does a magnetic resonance venogram have superior image quality to a CT venogram?

Does a magnetic resonance venogram have superior image quality to a CT venogram?

No, CT spacial image: Detail quality (partially older technology with more improvements over time) remains much superior to MRI. Yet CT is radiation, MRI (actually NMRI) no radiation, but slower, more noise & better at distinguishing soft tissue differences. Yet both only show location of dye in vein, not the vein itself, thus can easily miss issues present but not reflected in dye column. ...Read more

Had cardiac magnetic resonance angiogram. Saw both arterties, would they of seen if it was a myocardial bridging?

Maybe: The role of cardiac MRI in the diagnosis of myocardial bridging is unclear at this time. It would not be my choice of test if I suspected this diagnosis in one of my patients. This diagnosis is typically established during cardiac catheterization, supplemented by intravascular ultrasound. Ct angiography may be useful as well. ...Read more
