The overall objective of this protocol is to evaluate the safety and utility of diagnostic
MRI in Center for Medicare and Medicaid Services (CMS) beneficiaries with pacemakers and
Implantable Cardioverter Defibrillators (ICD) and clinical need for MRI.
A referring physician will request an outpatient MRI in an implanted device patient through
an order placed in the electronic ordering system, over the telephone to the MRI scheduling
office, or by directly contacting a radiologist or MRI technologist. Upon receiving such a
request, the referring physician will be sent a copy of the attached screening form, which is
used for all implanted device patients. The form includes instructions for obtaining approval
for the study and space for documenting ordering physician, study indication, and information
about the patient's implanted device (if their device is not followed by a UPHS physician).
For CMS beneficiaries, an addition to the form will discuss the clinical trial and ask the
referring physician how the results of the MRI will change patient treatment or prognosis and
what would be done were an MRI not available. The approval of an attending radiologist in the
radiology section that will be interpreting the study (e.g. neuroradiology for brain MRI,
cardiovascular imaging for cardiac MRI) is required.
Once the patient is deemed eligible and consented, the study staff will enter the patient
into the registry as well as register them onto the trial through PennChart.
