Injury to patient
◆ Explain to the patient how to behave during the procedure
and what to expect, as well as the risks involved.
◆ Inform the patient about the monitoring and communication
equipment e.g. squeeze ball, intercom.
◆ Instruct the patient regarding possible heat development
during the MR examination.
◆ Inform the patient about noise developing during the MR
examination.
◆ Prior to the MR examination, instruct patients of possible
stimulations during the examination i.e. twitching muscles,
tingling sensation.
Patients may be acoustically as well as visually and physiologically
monitored in the MR system.
◾ The viewing window or a video system is used for visual
monitoring.
◾ The intercom can be used to acoustically contact the patient.
( Page 70 Description)
◾ Medical supervision: MR Conditional monitoring devices are used
to monitor the patient's vital parameters, provided the conditions
for safe operation are observed.
Medical supervision means adequate medical management of
patients who can be at risk from some parameters of exposure to the
MR equipment, either because of the medical condition of the
patient, the levels of exposure or a combination.
All patients should receive at least routine monitoring. For some

(e.g. sedated, physically unstable) patients, monitoring of the
vital parameters is mandatory. In the First Level Controlled
Operating Mode medical supervision is also mandatory.
