How will the Test Feel?
There is no pain. The magnetic field and radio waves are not felt. The primary discomfort is the claustrophobic feeling that some people experience from being inside the scanner. The table may be hard or cold, but you can request a blanket or pillow.
The machine produces loud thumping and humming noises. Ear plugs are usually given to reduce the noise.
A technologist observes you during the entire procedure and may enter the room to speak to you or may speak with you through an intercom in the scanner.
Excessive movement can blur MRI images. If you have difficulty lying still or are very anxious, you may be given a sedative. The viewing of some brain lesions may require use of a dye injected into the veins. There is no recovery required (unless you have been sedated). After an MRI scan, you can usually resume normal diet, activity, and medications.
