Management of Patients with a CIED
Referred for MRI
Table 8. Implantable Loop Recorder
Recommendations COR LOE
It is recommended that prior to MRI scanning patients with an
implantable loop recorder (ILR) that the ILR be evaluated and
that any desired recorded information be removed/downloaded
from the system and cleared aer the MRI.
I B-NR
MR scanning of MR conditional ILRs should be performed
within labeled scanning prerequisites specific to each device
manufacturer.
I C-LD
Table 9. Employee Safety
Recommendation COR LOE
It is recommended that the MR suite has a clearly delineated 5
gauss boundary and visible signs to advise individuals who have
an implantable cardiac device, regardless of MR conditional
labeling, to stay outside of the 5 gauss boundary at all times.

Management of Patients with a CIED
Undergoing CT Imaging
Table 10. Recommendations for the Management of Patients
with a CIED Undergoing CT Imaging
Recommendations COR LOE
It is recommended that patients with a CIED undergo clinical
diagnostic CT without any additional device interrogation,
programming, or monitoring.
I B-NR
It is reasonable to exclude the device from the field of view
of 4D CT and cone-beam CT scans if the images are not
compromised.
IIa C-EO
It might be reasonable to monitor patients who have an ICD
or who are pacing-dependent by ECG or pulse oximetry if the
CIED will undergo prolonged, uninterrupted exposure by CT.
