What does this tool look like?

A characteristic MRI machine is a huge tube having a hole at both ends. A magnet surrounds this tube. You lay on a table that slides all the way into that tube. But yes in a short-bore system, you are not completely inside the MRI machine. Just the part of your body that is getting scanned is inside. The rest of your body remains outside the machine. Talking about an open MRI, it is open on all sides. This kind of machine might be finest if you have claustrophobia that is a condition of afear of tight spaces -- or you are extremely overweight. The quality of images that emerged from open MRI machines is not as good as it is with a closed MRI.

What really happen during the test?

Before some MRIs, you will receive contrast dye into a vein in your hand or arm. The dye helps the doctor to   see structures inside your body in a clearer manner. The dye mostly used in MRIs is called gadolinium. It might leave a metal taste in your mouth.You are going to lie on a table that slips into the MRI machine. Straps might be used to grip you still during the test. Your body may be fully within the machine. Or as mentioned above already, parts of your body might remain outside the machine. It depends on the doctor and the situation.
The MRI machine forms a strong magnetic field inside your body. A computer fetches the signals from the MRI and makes use of them to make a sequence of pictures. Every single picture shows a slim slice of your body.During the procedure you might hear a loud tappingor thumping sound. It is the machine creating energy to take pictures within your body. You can certainly ask for earplugs to soften the sound.


SO, whether MRI scans in Chennai or in your area, you can certainly go there and get a proper check- up. There is no need to feel afraid!
