MRI or magnetic resonance imaging is a technology that removes the detailed image of different parts of the body and detects the disease present in that part. Many times it becomes difficult for doctors to find out our body disease in a simple way. In such a situation, the disease is not known properly through CT scan.

Compared to CT scan, MRI scan holds the capacity to remove better and detailed picture of these parts of the body. Apart from this, no radiation is used in it, which harm the body. This is the reason why doctors recommend getting MRI scan.

MRI scan is a powerful medical imaging technique, which uses magnetic field to create a detailed image of the body. You will be surprised to know that the magnetic field of this machine is 30 thousand times more powerful than the magnetic field of the earth. It keeps the capacity to pull any metal thing in the room fast.

The MRI can pull even the wheelchair or iron cupboard kept in the room, which can prove to be fatal for the patient or the people with them. Due to this, there is always a danger of fire or any other kind of accident.

Before the MRI scan in the hospital, health and medical information of any patient is sought, so that the medical team can find out whether to scan it is safe or not. Apart from this, permission of the patient is taken. Due to the powerful magnetic field of the scanner, there should be no metal object on or inside the body of the patient, as it is at risk of life.

If a person has pacemakers, metal fake teeth, hearing machine or other such implants in his body, then his MRI cannot be done. Apart from this, there is no permission to take the clock, jewelery or any metal object inside the room.

Apart from this, this machine can also be dangerous for those who are afraid of closed space, because scanning takes some time long. In such a situation, they may have a panic attack. In pregnancy, doctors recommend to avoid this. Another shortage of MRI machine is that it causes a very loud sound during scanning. This voice can go from 100 to 120 decibels, which can be harmful to the ears.
