Table 6. Recommendations for the Decision to Perform an
MRI on Patients with an MR Nonconditional CIED
Recommendations COR LOE
It is reasonable for patients with an MR nonconditional CIED
system to undergo MR imaging if there are no fractured,
epicardial, or abandoned leads; the MRI is the best test for
the condition; and there is an institutional protocol and a
designated MR-responsible physician and CIED physician.
IIa B-NR
It is reasonable to perform an MR scan immediately aer
implantation of a lead or generator of an MR nonconditional
CIED system if clinically warranted.
IIa B-NR
For patients with an MR nonconditional CIED, it is reasonable
to perform repeat MRI when required, without restriction
regarding the minimum interval between imaging studies or the
maximum number of studies performed.

Table 7. Recommendations for the Management of Patients
with an MR Nonconditional CIED Who Are to Have
an MRI Scan
Recommendations COR LOE
It is recommended for the patient with an MR nonconditional
CIED that device evaluation be performed immediately pre
and post-MRI with documentation of pacing threshold(s),
P and R-wave amplitude, and lead impedance using a
standardized protocol.
I B-NR
A defibrillator/monitor (with external pacing function) and
a manufacturer-specific device programming system should
be immediately available in the holding area adjacent to the
MR scanner room while an MR nonconditional CIED is
reprogrammed for imaging.
I B-NR
It is recommended that continuous MR conditional ECG
and pulse oximetry monitoring be used while an MR
nonconditional CIED is reprogrammed for imaging.
I B-NR
It is recommended that personnel with the skill to perform
advanced cardiac life support, including expertise in the
performance of CPR, arrhythmia recognition, defibrillation,
and transcutaneous pacing, accompany the patient with an MR
nonconditional CIED for the duration of time the patient's
device is reprogrammed, until assessed and declared stable to
return to unmonitored status.
