Hi OT! MRI scans can show soft tissue much better than x-rays. You have to undress and put on a gown. Also, you have to remove anything metal such as necklaces, watches etc. This is because it uses a strong magnetic field and if there is anything metal and loose, it will fly around and cause injury and damage. The ed is right, you do get fed into a tube but it can be a bit claustrophobic. They give you a panic button to press if you cannot stand it. It is also a painless procedure.
