Non-contrast enhanced pulmonary vein (PV) MRI is an alternative to contrast-enhanced PV imaging for assessment of PV anatomy prior to and after PV isolation as a treatment for atrial fibrillation [1, 2]. We propose a non-contrast enhanced three-dimensional (3D) free-breathing ECG-gated thin-slab spoiled gradient recalled echo (GRE) sequence with a slab-selective inversion for PV MRI.
The proposed technique greatly enhances the conspicuity of the PVs and LA without significant loss of SNR.
