In the context of cardiovascular diseases, precise determination of the extent and locations of the arrhythmogenic substrate could significantly improve diagnosis and treatment for both atrial and ventricular electrical diseases. However, the current spatial resolution and signal-to-noise ratio (SNR) in clinical scanners remain insufficient to provide relevant information of small structures like atrial wall or sub-millimeter fatty infiltration in ventricle. To address this limitation in SNR, two receiver coils were implemented at 1.5T for high resolution cardiac imaging, with different active decoupling techniques (safety aspects). Images at 200 µm in-plane spatial resolution were successfully obtained on a beating heart.
