Artifacts due to the presence of metallic dental materials often limit the application of MRI. These materials, such as dental implants or fillings, often cause substantial artifacts e.g. in the oral cavity impairing diagnostic accuracy. In this contribution, we present an approach for conducting spin-echo based sequences with significantly reduced flip angles and high excitation bandwidths of up to 17 kHz by using an inductively coupled local coil, which in combination with single-point methods enables almost completely artifact-free local imaging of e.g. dental titanium implants.
