A magnetic field and radio waves produced by a computer are used in the medical imaging procedure known as magnetic resonance imaging (MRI), which produces precise images of your body's organs and tissues.
Large, magnetised tubes make up the majority of MRI equipment. The magnetic field in an MRI machine causes your body's water molecules to momentarily rearrange. These aligned atoms emit tiny signals that are used to make cross-sectional MRI pictures, which resemble the slices of bread.
Additionally, the MRI scanner can create 3D images that may be viewed from various perspectives.
Why is it done?
Your doctor can evaluate your organs, tissues, and skeletal system using MRI in a noninvasive manner. It creates detailed images of the inside of the body that aid in the diagnosis of many conditions.
MRI scans of the spinal cord and brain
The brain and spinal cord imaging test that is most frequently utilized is the MRI. It is frequently done to assist in diagnosing:
vein aneurysms in the brain
disorders of the inner ear and eyes
a number of scleroses
spinal cord conditions
Stroke
Tumors
trauma-induced brain damage
The functional MRI of the brain is a unique variety of MRI (fMRI). It creates visual representations of blood flow to particular brain regions. It can be used to investigate the structure of the brain and identify the regions of it responsible for crucial functions.
This aids in locating crucial language and motor control regions in the brains of patients who may undergo brain surgery. Functional MRI can also be used to evaluate damage caused by conditions like Alzheimer's disease or head injuries.
Yes, having a sewing needle embedded in the foot could be dangerous if you were to have an MRI. The magnetic field of the MRI machine could cause the needle to move or potentially injure the surrounding tissue. It is important to inform your healthcare provider or the MRI technologist if you have a foreign object in your body before undergoing an MRI.
No, an MRI does not emit radiation during the imaging process.
MRI systems are significantly stronger than refrigerator magnets, with MRI systems typically having magnetic fields thousands of times stronger than refrigerator magnets.
MRI uses radiofrequency electromagnetic waves to create detailed images of the body's internal structures.

If the MRI technologist positions you with your leg going into the magnet (the MRI machine) then your head would be out of it. Call the facility where you are scheduled to have the MRI and ask to speak with the MRI technologist and they can fully explain to you exactly how you will be positioned.

No. It is not a treatment it is a scan. An MRI is a Magnetic Resonance Imaging. MRI are used for imaging tissues.

The agency that referred the patient for the MRI; the doctor or clinic.
An open MRI is an MRI that, unlike usual MRI's let patients enjoy space and comfort while continuing to have their insides scanned. The technician in this context of the question would oversee the MRI screening process.
MRI Software was created in 1971.
