  Magnetic resonance late gadolinium enhancement images compared with voltage maps of the heart using electrophysiology, and a representation of the MR scar pattern.

Key Investigators

• Beth Israel Deaconess Medical Center: Dana C. Peters, Felix Liu

Objective

We wish to represent the MR scar images in 3D to compare with voltage maps. This will lead to interpretation of the relationship between EP findings and scar.

Approach, Plan

Our approach includes segmentation of the scar, representation, registration with voltage maps, and quantitative evaluation.

Progress

None so far.
