Summary
The purpose of the registry is to accumulate pre-and post-scan device interrogation data for the purpose of determining the risk of MRI for patients with implantable devices.
Eligibility Criteria
- Patient has a non-MRI conditional permanently implanted pacemaker or ICD implanted after 2001
- Patient has a strong clinical indication for MRI where MRI is the diagnostic modality of choice for specific disease state without acceptable alternative imaging technologies as determined by the ordering physician and a radiologist
- Patient is at least 18 years of age
- Patient is willing and able to sign study informed consent and HIPAA authorization
Exclusion Criteria
- Non-device related contraindication for MRI (such as implanted metallic objects, claustrophobia, morbid obesity)
- Presence of capped/abandoned/epicardial leads or subcutaneous coil
- Pregnancy
- Device generator at elective replacement interval
- Abdominal device implant
