Eligibility

Inclusion Criteria:

• Strong clinical indication for MRI; in the clinical setting where MRI is the diagnostic modality of choice for a specific disease state without acceptable alternative imaging technology
• Male or Female
• 18 years of age or older
• Able to provide informed consent
• Presence of CIED

Exclusion Criteria:

• Presence of metallic objects that represent a contraindication to MR imaging, including: MRI-unsafe intra-orbital or intra-ocular retained metal fragments, and MRI-unsafe intracranial vascular clips and coils, other MRI-unsafe devices
• Morbid obesity (abdominal diameter greater than 60 centimeters) which results in contact wiht the magnet bore.
• Pregnant at time of scanning Pacemaker or Implanted Cardiac Device that is labeled as MRI-Conditional (approved by the Food and Drug Administration for exposure to MRI)
• Pacemaker dependent and either: 1) device implanted before 2005, or 2) advisory pulse generator that may lower outputs in the setting of radiofrequency currents
