3D Late Gadolinium-Enhanced (LGE) imaging is used to assess scarring in patients with Atrial Fibrillation (AF). Acquiring image data during every cardiac cycle allows a reasonable total scan duration but exacerbates ghosting artefacts caused by variable heart rates, such as those of patients with AF. Dynamic Inversion Time (TI) methods improve image quality by modifying the TI for each cardiac cycle. We present the initial stage of a patient study to validate a recently-proposed blood-focused dynamic TI algorithm. No improvement was found in comparison to the original algorithm. Future comparisons will include more patients with high R-wave interval variability.
