What is an MRI Scan?
Magnetic Resonance Imaging, also termed as MRI Scan, is an advanced technique that uses strong magnetic fields and radio waves to look at tissues, organs & other structures inside the body and then allows to take clear pictures of the same. An MRI scanner is a large tube that contains extremely strong magnets. When a patient lies inside this tube, the magnetic field realigns the hydrogen atoms in your body on temporary basis. These aligned atoms then produce very faint signals under the effect of radio waves. With the help of this, cross-sectional MRI images are formed. MRI scan also produces 3D images that can be seen from different angles.
What happens during MRI scan?
During MRI scan, the patient is made to lie on a flat surface or a table. Then this table slides into tunnel-shaped machine. It is important that the patient lies completely still during the procedure so that proper images can be taken. MRI scan usually takes 20-45 minutes. One must have patience while the scanning is going on. If you have claustrophobia and feel uncomfortable, you must talk to your radiographer and with his support, the whole procedure will become easy. The MRI scan makes a lot of noise, therefore, your radiographer will give you ear plugs.
MRI scan is a very safe and painless procedure that doesn’t expose your body to X-ray radiation. Hence, if required even pregnant women and children can also go through procedure safely. But there are some people who can’t have MRI scan, like, a person who has had pacemaker implant.
What can MRI diagnose?
MRI is a non-invasive method that is used to examine almost all parts of your body. The various body organs that can be scanned with the help of MRI are:
- Brain and spinal cord
- Heart and blood vessels
- Bones and joints
What diseases can be diagnosed with MRI?
With the help of MRI scan, your doctor can diagnose your medical condition and then accordingly plan a proper treatment plan so that you can get relief from your problems as soon as possible. A number of medical problems can be diagnosed with this help of this ultra-modern techniques, that includes:
- Spinal cord injuries
- Brain injury
- Aneurysms of cerebral vessels
- Damage caused by heart attack
- Problem in the structure of aorta
- Blockages in blood vessels
- Bone infections
- Torn cartilage/ligaments and many more
It has been found out by researchers that MRI scan doesn’t pose any threat to the patient and hence it is a very safe procedure for almost all.
