Magnetic resonance examinations are long and require the patient to be in a resting state to be examined. Therefore, the examination can be better done in a sleeping state. Generally, children and some agitated patients need to be examined under the use of sedative and sleeping agents, at this time the patient is in a sleeping state. However, there are some examinations that require the patient to be awake, such as abdominal magnetic resonance examination, which requires the patient to cooperate with the inhalation and then hold his/her breath, and the patient should not be in the sleeping state at this time.
