Late gadolinium enhancement (LGE) MRI can be used to assess extent of the left atrial wall injury and validate tissue destruction during RF ablation procedure for treatment of atrial fibrillation. However, conventional contrast agents have fast clearance times making them less useful in the settings when LGE-MRI should be performed multiple times during interventional procedure. Blood pool contrast agents have noticeably longer clearance times. However, these agents have not been tested as contrast agents for LGE-MRI of acute atrial lesions. In this study, we examine applicability of blood pool contrast agent to visualize acute atrial lesions.
