What medications are used? Propofol will be given through an I.V. to induce sleep. This medication has a short duration of action and a rapid recovery time and is administered to make sure you remain asleep during the entire MRI study.
Since the MRI machines are magnets, it is best to not apply deodorants, antiperspirants, perfumes, or body lotions before the examination. These items contain metals that might interfere with the magnetic field inside the MRI machine and cause you to have distorted images and wrong results.
An MRI can cost consumers between $300 to $1000, depending on the area of the body being scanned and the reason for the scan, the ADIA says.
