Despite the tremendous effort to develop MRI safety protocols to reduce complications in patients with cardiac implantable electronic devices with intact leads, almost nothing is known about the variation and extent of RF heating in patients with fractured or abandoned leads. Here we report the preliminary results of the first systematic simulation study of RF-induced SAR amplification at and around abandoned cardiac leads in patients undergoing MRI at 1.5 T and 3.0 T with different imaging landmarks.
