Feasibility and Accuracy of Cardiac Magnetic Resonance Imaging–Based Whole‐Heart Inverse Potential Mapping of Sinus Rhythm and Idiopathic Ventricular Foci

摘要

BackgroundInverse potential mapping (IPM) noninvasively reconstructs cardiac surface potentials using body surface potentials. This requires a volume conductor model (VCM), usually constructed from computed tomography; however, computed tomography exposes the patient to harmful radiation and lacks information about tissue structure. Magnetic resonance imaging (MRI) is not associated with this limitation and might have advantages for mapping purposes. This feasibility study investigated a magnetic resonance imaging–based IPM approach. In addition, the impact of incorporating the lungs and their particular resistivity values was explored.
