Recently a accident took place in Mumbai.MRI machine which is generally used for body checkup,took life of a person.
we will learn about the principle behind MRI and safety precaution which should be taken during MRI scanning.
MRI means magnetic Resonance Imaging.This machine works on magnetic field instead of radiation.that's why it is different from x-ray and CT scan.Generally this process takes 20-90 minute and depends on the size ,part of the body and number of pictures to be taken.Generally machine magnetic field is in the range of 1-3 Tesla.More Tesla means stronger magnetic field.
Our body made up of 70% water.Hydrogen nuclei present in the water get aligned in the presence of magnetic field.A very strong magnetic field is applied which interfere the spin of the hydrogen nuclei.When machine is turned off nuclei comes in to original state.The process is recorded by the receiver of the scanner and image is formed.
Brain,knees ,spinal cord and other parts of the body where the soft tissues are present are scanned using MRI then problem can be found out after analyzing the image formed by hydrogen spin.
There should not be any metal object present in your body.Metal objects like watches,hearing ads,jewelries,piercings,pacemaker etc are strictly prohibited inside the room.During scan a lot of noise happens due to electric current so patients are given headphone to listen music or instructions given.
