a patient is exposed to short bursts of powerful magnetic fields and radio waves from electromagnets. MRI images do not utilize potentially harmful ionizing radiation generated by three-dimensional x-ray computed tomography (CT) scans
The agency that referred the patient for the MRI; the doctor or clinic.
Yes
MRI scanning should not be used when there is the potential for an interaction between the strong MRI magnetic field and metal objects that might be imbedded in a patient's body.
yes
It depends on the scan, and your age. For an fMRI or Functional MRI exam, the patient is asked to perform a wide variety of tasks, like playing games. If a child is to be scanned, they are usually sedated, so therefore cannot play any games whatsoever.
An MRI may show brain changes in a patient that has bacterial meningitis. However, the diagnosis is not given based on images alone.
A final MRI is done with the frame in place to help set the coordinates of the GPi in relation to the frame.
Common conditions like the flu or a cold do not often require a chest MRI. However, when a person suffers from a deep cough or blood sputum, his or her doctor might order this test to find out from what infection the patient suffers. An MRI can detect lung conditions like pneumonia and pulmonary fibrosis. If the patient's condition is not terminal or too advanced, the patient's pulmonary doctor may be able to prescribe antibiotics.
There are different types of MRI devices, however, one of the biggest and most common things that would disqualify a patient getting an MRI would be metal in the body. Surgical pins, staples in the stomach and the like.
Because the pituitary gland is in the brain.
MRI's work by magnets, not radiation. There is no exposure to radiation involved so therefore it's safer for the patient and lower risks are involved.
Yes as long as it has no metal in it. If it has any metal then no, as an MRI is like a giant magnet.
