MRI measurements of ex-vivo hearts at ultrahigh field strengths (≥7T) can provide high resolution, high fidelity ground truth data that complement clinical cardiac MRI. In this study we demonstrate ex-vivo sample preparation steps and capabilities of a custom built, multiple element transceiver array dedicated to high resolution imaging of ex-vivo hearts. Measurements included whole heart data for T2* maps, a high resolution 3D FLASH, as well as high resolution DTI. We found that receive sensitivity of the dedicated coil was superior to a commercial head coil and that SNR was similar, even without the application of B1­-shim.
