Video Summary

The talk presented a non-contrast MR “boost” sequence for atrial fibrillation planning that simultaneously provides bright-blood anatomy of the heart and coronary sinus, plus co-registered black-blood images for measuring atrial wall thickness. Unlike standard navigator-gated methods, it aims for 100% scan efficiency and predictable scan time. The new MT-prepared version improved visualization of venous structures and coronary sinus compared with T2-prepared imaging, while preserving arterial image quality. In 11 healthy volunteers, it enabled accurate atrial wall segmentation and thickness measurements (~2.5 mm). Future work will test the method in atrial fibrillation and congenital heart disease patients.
