Electromagnetic interference cancellation method EDITER is implemented in an unshielded low-field MRI scanner at 100mT by addition of only two EMI detection coils to the acquisition chain. The method’s effectiveness is illustrated in high resolution MSK images of healthy volunteer’s hands. Full 3D images with sub-millimeter in-plane or isotropic millimeter voxel dimensions can be obtained in clinically acceptable acquisition times. This approach, in combination with acceleration strategies, opens perspectives in MSK imaging in the field with portable scanners and/or in low resource environments.
