How to Prepare for an MRI

Posted on by

MRI, or magnetic resonance imaging, is a medical technique that uses a magnetic field and computer-generated radio waves to create detailed images of the body’s organs and tissues.

MRI is a noninvasive way for a medical professional to examine your organs, tissues, and skeletal system, producing high-resolution images of the inside of the body that help diagnose several conditions. The MRI machine also produces 3D images that can be viewed from different angles. Parts of the body that MRI takes images of include:

  • Brain and spinal cord
  • Heart and blood vessels
  • Internal organs
  • Bones and joints
  • Breasts

Before an MRI exam, eat as you normally would, and continue to take your usual medicines, unless you are told otherwise. You will typically be asked to change into a gown and to remove things that might affect the magnetic imaging, such as:

  • Jewelry
  • Hairpins
  • Eyeglasses
  • Watches
  • Wigs
  • Dentures
  • Hearing aids
  • Underwire bras
  • Cosmetics that contain metal particles

Most MRI machines are large, tube-shaped magnets. When you lie inside an MRI machine, its magnetic field works with radio waves and hydrogen atoms in your body to create cross-sectional images.

If you have a fear of enclosed spaces, also known as claustrophobia, you might receive a drug to help you feel sleepy and less anxious. An MRI exam can last anywhere from 15 minutes to more than an hour. You must hold still because movement can blur the images. Most people get through the exam without difficulty.

If you haven’t been sedated, you can resume your usual activities immediately after the scan.

For the results, a radiologist will look over the images from your scan and report the findings to your doctor. Your doctor will then discuss important findings and next steps with you.

#TBT — The History of Magnetic Resonance Imaging or MRI

Posted on by

Physicians often send patients for Magnetic Resonance Imaging or MRI’s to help them diagnose certain medical conditions, but do you know what an MRI is?

mri-300x200In 1977 the first human scan was performed in a prototype MRI machine. An MRI is a computerized map of harmless radio signals emitted by the human body. MRI works by creating a strong magnetic field where protons in the nucleus of the hydrogen atoms are magnetized. It is excellent for viewing soft tissue and seeing any defects that may be present.

The rotating magnetic field was discovered by Nikola Tesla in 1882. This eventually led to the definition of the Tesla Unit which describes the strength of a magnetic field. MRI machines, which were developed almost a century later, are calibrated in Tesla Units. The stronger the magnetic field, the stronger the amount of radio signals that are given off by the body’s atoms. The stronger the radio signal will lead to a better quality of the MRI image.
