Respiratory bellows-gated left atrial late gadolinium enhancement
Introduction The LGE method can visualize post-ablation scar in the LA, using increased spatial resolution (1-2). However, the inversion pulse required for LGE also nulls the liver signal at the time of data acquisition (optimal TI time), so that NAV-gating, used for respiratory compensation, becomes impossible. The NAV-restore (3), which reinverts the region of the liver immediately after the ...
متن کاملSelf-navigated 3D late gadolinium enhancement imaging of the left atrium
Introduction: Late Gadolinium Enhancement imaging is evolving as a valuable tool for treatment management of atrial fibrillation using radio-frequency ablation [1, 2]. Enhancement in images post-ablation correlates with regions of ablation [1, 2] that can be used to track treatment progress and identify gaps in the ablated regions. In pre-ablation images, enhancement corresponds to fibrosis whi...
متن کاملIschemic late gadolinium enhancement.
While research exploring the utility of intravascular gadolinium based contrast agents (GBCA), such as gadofosveset (Vasovist, ABLAVAR) is ongoing, cardiac MR is currently routinely performed with administration of standard extracellular GBCAs, e.g. Gd-DTPA (Magnevist) or Gd-BOPTA (Multihance). LGE is a phenomenon related to the distribution of the extracellular GBCAs. Upon intravenous injectio...
متن کاملCompressed sensing for rapid late gadolinium enhanced imaging of the left atrium: A preliminary study.
Current late gadolinium enhancement (LGE) imaging of left atrial (LA) scar or fibrosis is relatively slow and requires 5-15min to acquire an undersampled (R=1.7) 3D navigated dataset. The GeneRalized Autocalibrating Partially Parallel Acquisitions (GRAPPA) based parallel imaging method is the current clinical standard for accelerating 3D LGE imaging of the LA and permits an acceleration factor ...
