MRI does not expose the person to radiation. Drawbacks of MRI include claustrophobia and high cost. [31] For children, sedation may be required to undergo MRI imaging, which is an increased risk when the airway is already potentially compromised.
This level, called moderate sedation/analgesia or conscious sedation, causes a drug induced depression of consciousness during which the patient responds purposefully to verbal commands, either alone or accompanied with light physical stimulation. Breathing tubes are not required for this type of anesthesia. This is twilight anesthesia. [2]
Cardiac magnetic resonance imaging (cardiac MRI, CMR), also known as cardiovascular MRI, is a magnetic resonance imaging (MRI) technology used for non-invasive assessment of the function and structure of the cardiovascular system. [2]

Although painless, MRI scans may be unpleasant for those who are claustrophobic or otherwise uncomfortable with the imaging device surrounding them. Older closed bore MRI systems have a fairly long tube or tunnel. The part of the body being imaged must lie at the center of the magnet, which is at the absolute center of the tunnel.
The knock-on psychological effects of the situation could include a growing sense of claustrophobia, leading to increased heart rates, light-headedness, nausea and panic attacks, which could cause ...
The MRI machine looked pretty standard, except that there was a screen with Netflix queued up. The facilitator put a weighted cover (almost like a blanket) over my legs and chest so I stayed still.
The present case series with two patients explored whether virtual reality (VR) distraction could reduce claustrophobia symptoms during a mock magnetic resonance imaging (MRI) brain scan. Two patients who met DSM-IV criteria for specific phobia, situational type (i.e., claustrophobia) reported high levels of anxiety during a mock 10-min MRI ...
