Where Can I Get an Mri Near Me

Magnetic resonance imaging (MRI) is a type of scan that uses stiff magnetic fields and radio waves to produce detailed images of the inside of the body.

An MRI scanner is a large tube that contains powerful magnets. Yous lie inside the tube during the scan.

An MRI scan can be used to examine well-nigh any part of the torso, including the:

• encephalon and spinal string
• bones and joints
• breasts
• heart and blood vessels
• internal organs, such equally the liver, womb or prostate gland

The results of an MRI scan can exist used to help diagnose weather, plan treatments and assess how effective previous handling has been.

What happens during an MRI scan?

During an MRI browse, you lot lie on a flat bed that'south moved into the scanner.

Depending on the part of your body existence scanned, you'll exist moved into the scanner either caput offset or anxiety first.

The MRI scanner is operated by a radiographer, who is trained in conveying out imaging investigations.

They control the scanner using a computer, which is in a different room, to keep it away from the magnetic field generated by the scanner.

You'll exist able to talk to the radiographer through an intercom and they'll exist able to come across you on a television monitor throughout the scan.

At certain times during the scan, the scanner will make loud borer noises. This is the electrical electric current in the scanner coils being turned on and off.

Y'all'll be given earplugs or headphones to habiliment.

It's very of import to keep as even so equally possible during your MRI browse.

The scan lasts 15 to 90 minutes, depending on the size of the area beingness scanned and how many images are taken.

How does an MRI browse work?

Nigh of the human body is made up of water molecules, which consist of hydrogen and oxygen atoms.

At the middle of each hydrogen atom is an even smaller particle called a proton. Protons are similar tiny magnets and are very sensitive to magnetic fields.

When you lie under the powerful scanner magnets, the protons in your trunk line upwards in the same direction, in the same fashion that a magnet can pull the needle of a compass.

Short bursts of radio waves are then sent to certain areas of the body, knocking the protons out of alignment.

When the radio waves are turned off, the protons realign. This sends out radio signals, which are picked upwardly by receivers.

These signals provide information about the exact location of the protons in the body.

They also help to distinguish between the various types of tissue in the body, because the protons in unlike types of tissue realign at different speeds and produce distinct signals.

In the aforementioned mode that millions of pixels on a figurer screen can create complex pictures, the signals from the millions of protons in the body are combined to create a detailed epitome of the within of the body.

Safety

An MRI browse is a painless and safe procedure. Y'all may observe it uncomfortable if you have claustrophobia, but well-nigh people are able to manage it with support from the radiographer.

Going into the scanner feet first may be easier, although this isn't ever possible.

All-encompassing enquiry has been carried out into whether the magnetic fields and radio waves used during MRI scans could pose a chance to the human trunk.

No evidence has been found to suggest in that location'south a risk, which means MRI scans are one of the safest medical procedures available.

But MRI scans may non be recommended in certain situations. For example, if you lot have a metal implant fitted, such every bit a pacemaker or artificial articulation, you may non exist able to have an MRI scan.

They're too non commonly recommended during pregnancy.
