Synopsis

Interleaved undersampled radial linear-combination balanced SSFP (LC-SSFP) was investigated as a method for improving cardiac cine images, acquired in subjects with metallic implants. Phantoms and healthy volunteer studies were performed, in the presence of metallic artifacts (generated by a stainless steel bolt). We found the proposed method eliminated some artifacts seen using standard Cartesian bSSFP. These findings may lead to improved cardiac cine imaging for patients with a pacemaker or implantable cardioverter defibrillator (ICD).
