We have modified a 3D IR-FLASH sequence for LGE cardiac
MRI of patients with implanted cardiac devices. We show
that a conventional 3D FLASH sequence produces artifacts
which do not appear in corresponding 2D wideband LGE
images. We optimizied the 3D LGE sequence by
implementing a wideband IR pulse and by increasing the
bandwidth of the excitation pulse. We show that this
modified 3D wideband LGE sequence is very promising in
removing aforementioned artifacts and produce high
resolution images in patients with cardiac devices.
