Cardiac functional magnetic resonance imaging at 7T: Image quality optimization and ultra-high field capabilities

Figure 5 Improved image resolution achieved at 7T cardiac magnetic resonance imaging. High signal-to-noise ratio (SNR) at 7T allows for achieving high spatial resolution with 16-fold reduction in voxel size (A) compared to standard clinical resolution in (B). Small voxel size illustrates anatomical details, such as the trabeculations and right ventricle details (arrows), that are not clearly visible at standard clinical resolution. Alternatively, high SNR can be traded for high temporal resolution (approximately 20 ms) imaging at conventional spatial resolution as in (B).
