Imaging of MR-Conditional metal implants becomes routine with Compressed Sensing
Conventional Imaging of a hip replacement (left) vs. SEMAC with Compressed Sensing acceleration. SEMAC allows complete removal of artifacts and stable fat suppression in the presence of MR-conditional metal implants. By introducing Compressed Sensing acceleration to this clinically decisive method, time savings of up to 51% are possible, enabling to establish SEMAC in daily clinical routine. (Compressed Sensing SEMAC is included in the Turbo Suite Excelerate package.)

CS SEMAC is pending 510(k) clearance, and not yet commercially available in the United States.
The MRI restrictions (if any) of the metal implant must be considered prior to patient undergoing MRI exam. MR imaging of patients with metallic implants brings specific risks. However, certain implants are approved by the governing regulatory bodies to be MR conditionally safe. For such implants, the previously mentioned warning may not be applicable. Please contact the implant manufacturer for the specific conditional information. The conditions for MR safety are the responsibility of the implant manufacturer, not of Siemens Healthineers.
