MRI (Magnetic Resonance Imaging. MRI creates clear images of the body’s internal structures: organs, muscles, bones and blood vessels. MRI is a painless, non-invasive diagnostic test which is based on magnets, radio waves and a computer, but no radiation.

In this article we have covered What is MRI, why it is required and how one can prepare for it

What is an MRI Scan?

Two types of MRI imaging machines are : open MRI and closed MRI.

In an open MRI machine, the structure is more open in comparison with a closed MRI with both sides open, and two magnets placed on the top and bottom of the table on which the patient lies.

A closed MRI machine resembles a tube-like structure open only at the entrance. It is closed and comprises a ring of magnets. A closed MRI can take better images than an open MRI, however sometimes is a little uncomfortable for certain patients.
