what is the definition or description of: magnetic resonance imaging?

Question

Is there any pain involved in a proton magnetic resonance spectroscopic imaging?

Answer 1

Magnet: A magnet is used to create a magnetic field; the different cells of the body react at difference speeds; this produces an image.

Answer 2

Details: An MRI provides a very detailed picture of the soft tissue. Because the soft tissue of muscle is different that the soft tissue of the bowels, which is different than the soft tissue of the blood vessels, etc., an MRI delineates all these different tissues very distinctly.

Answer 3

Nice pictres...: A very hi-tech, no radiation way of taking pictures of our bodies to aid doctors in helping pinpoint what is going on in a particular area of our body.

Answer 4

MRI: Mri is a noninvasive medical test that helps physicians diagnose and treat medical conditions. Mri uses a powerful magnetic field, radio frequency pulses and a computer to produce detailed pictures of organs, soft tissues, bone and virtually all other internal body structures. Detailed mr images allow physicians to evaluate various parts of the body and determine the presence of certain diseases.

Answer 5

A lot: Mri is superior. Utrasound reliable in total block or excellent flow but unable to determine degrees of stenosis.

Answer 6

Good screening test.: Cta best for imaging carotid arteries. Mra can be used but often overestimates the amount of stenosis.

Answer 7

Mostly technical: The carotid arteries are well seen on Carotid duplex scanning. The problems are whether we can get good images of the arteries due to the patients anatomy. Sometimes thick necks and relative positon of the vessels make it hard to see them. The other issue is that when the carotid arteries enter the skull, they can no longer be seen on ultrasound.

Answer 8

None vs. MRI: In most cases, the diagnosis of tendonitis doesn't require any imaging whatsoever. That being said, I do find that tendonitis is frequently reported on mris of various joints, so if really warranted, it would be my choice of study.

Answer 9

MRI: Tendonitits is an inflammation which is self resolving with rest and physical therapy. But anything suspect of tears would require imaging. The best modality is the MRI which has high fidelity for soft tissues.

Answer 10

MRI: The reason why an MRI can be extreemely valuable is because sometimes one has a tendonitis and other times a patient has a tendinosis which is a degeneration of a tendon. This can be an important distinction depending on ones level of activity. Treatments can differ in both situations.

Answer 11

Yes: The most common pituitary tumor is an adenoma which is benign. Cancer is very rare in the pituitary gland.

Answer 12

Perhaps: Mri of the brain with contrast (gado) can show a pituitary tumor but it won't always distinguish cancer from benign tumor. You will need a biopsy (surgical) to fully confirm the diagnosis. Please discuss fully with your neurosurgeon.
