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 74 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.
 CAUTION
Incompatible monitoring devices!
Patient burns
◆ Use only monitoring devices, for example, ECG electrodes and
pulse sensor, that meet the conditions for safe use (MR Safe
or MR Conditional).

Artifacts and imaging errors

2.3.5
Due to their magnetizability, foreign objects in the area of the
magnet bore cause strong local distortions of the basic field and lead
to considerable image artifacts. Depending on the level of distortion,
diagnosis may be difficult, impaired or completely impossible.
