To answer what kind of sedation is used for an MRI, it varies by the doctor who orders the test. For a child or infant who cannot understand instructions, general anesthesia with a breathing tube and anesthetic gas may be needed. For an adult who has no history of claustrophobia, a fear of being in an enclosed space, nothing may be used. For an adult who understands and is healthy, mild sedation is usually in the form of a pill of diazepam, also known as Valium. A prescription is usually sent to a local pharmacy close to the patient's home, for 1 or 2 tablets. If you are an adult who has medical problems or is completely unable to lay still for an MRI, there are two possibilities: sedation with an IV or general anesthesia. Intravenous liquid diazepam or a similar one like midazolam, which also makes you have amnesia and forget everything, can be used with pain medication like fentanyl. The anesthesiologist answers all your questions before the procedure and watches over you to be sure everything goes very well.

Anesthesia "knocks you out" so fast because of the way it is delivered into your body. Either you inhale the gases, which go to your lungs, or you get it through an intravenous plastic catheter in your vein. Either way, it goes to your brain really fast and that is why you fall asleep before you can count backwards from 100 to 90.
