What is MRI scan and its uses

In this post, we are going to talk about what an MRI scan is, how an MRI scan is done, and what are the things to be taken care of before an MRI scan.

What is MRI scan

The full-form of MRI is magnetic resonance imaging. The photo of the organs inside your body is taken in this scan using powerful magnets, radio waves, and a computer. It combines small protons present in our body and takes photos of them.

 In simple language, there is a machine that takes photographs of the inner parts of our body. It also detects micro to micro things in our body.

Why is an MRI scan done?

 The development of MRI has taken the medical world forward because, with its help, doctors can see internal organs in a very accurate way without having to deliver any kind of equipment in the body.

 MRI scans help doctors treat disease and injury. With its help, doctors can monitor how well the treatment is working on the patient.

 This test is also used to know which part of the brain is more dynamic when you do some special work.

 MRI scans can detect problems associated with the brain, such as stroke. If there is a need for brain surgery in the case of a tumor, then brain mapping is done with the help of fMRI. To prepare a treatment plan, the doctor also uses MRI.

How does an MRI scan happen

 To get the MRI scan done, the person has to wear all the white clothes given by the physician. All the metal items are removed before performing an MRI scan. The man is then laid on top of the MRI scan machine table and sent inside the machine.

 After that, the machine uses powerful magnets, radio waves, and the computer to take pictures of inside the human body which are small protons in the human body.

With the same scan, doctors can easily find out which disease is in the human body and how old the disease can be.

 Pregnant women should always tell their doctor or technologist that I am pregnant so that it does not have any ill effects on pregnant women or unborn children.

If you do not want to have an MRI scan of the entire body, then you can get an MRI scan of the place where there is an injury or the place where there is any disease.

MRI can be used to detect brain tumors, traumatic brain injury, developmental anomalies, multiple sclerosis, stroke, dementia, infection, and the causes of headaches.

 If you want to have a full MRI scan of your body then you can get that done as well. If you have any other disease in your body then it can also be detected.

 MRI scans of one part cannot be detected by other parts of the body.

What are the things you should keep in mind during MRI scan

 When you get an MRI scan, you should give your complete information to the doctor, such as

  • Tattoo done somewhere.
  • Anything fitted in teeth or ears.
  •  If there any kind of rod in the bone or the metal was surgery before. 
  •  All kinds of allergies you have.
  • If you have done any surgery before.
  •  If you using any medicines for a long time.


During MRI, no metal is allowed in the room because magnetic fields can attract the metal in the machine.

 You can be forbidden to eat anything for up to 4 hours before an MRI scan. And sometimes you may be asked to drink a lot of water beforehand. 

 Although there is no pain in the MRI scan, if contrast is needed then there is definitely you could some pain.

 This test may take from 30 to 90 minutes. 

MRI machine creates noise, to reduce that they will give you a headphone in which music is running.
