Cardiac MRI in the Setting of Implanted Pacemaker or ICD

Common conditions

• Cardiac viability evaluation
• Cardiac function evaluation
• Pre-ablation planning
• Sample Image

What are some key elements of this study?

• Pre-imaging evaluation by electrophysiology clinic
• Pre-imaging device programming by an electrophysiology NP
• Monitoring throughout the examination by electrophysiology NP
• Post-exam device reprogramming

Why this modality?

Ability to evaluate function and tissue viability/scarring

Who reads these studies?

Cardiac radiologist

What to do if there is a finding?

Followup with cardiologist

Why get this done at UCLA Radiology?

• One of few sites with a comprehensive implanted pacemaker/ICD scanning program including pre-imaging screening and monitoring throughout the image acquisition. We performed nearly 700 MR exams with implanted cardiac devices in 2019
• UCLA physicist Peng Hu developed the broad band protocol for acquiring cardiac images in the setting of pacemakers/ICD while minimizing artifact (now adopted at sites worldwide)
• Experienced MR technologists
• Onsite physician feedback and collaboration with MR technologists
