We developed a wideband-IR LGE technique to eliminate
the hyper-intensity artifacts seen in LGE MRI of
patients with implantable cardioverter defibrillators (ICDs).
This technique was implemented at two institutions and
evaluated on 25 patients. The new wideband LGE sequence
was compared with the conventional (narrowband-IR) LGE
sequence by quantifying hyper-intensity artifacts. While
hyper-intensity artifacts were prominent in the
conventional LGE images, artifacts were completely
eliminated in the wideband LGE images. The wideband LGE
technique may enable widespread utility of LGE MRI in
patients with implanted cardiac devices, in whom LGE MRI
otherwise could not be used for diagnosis.
