Aims and objectives
Motion-induced artifacts are a well-known challenge for dynamic contrast- enhanced abdominal MR imaging.
Especially elderly patients and severely ill patients are often unable to adequately perform breath-hold maneuvers with a risk of critically reduced image quality due to motion artifacts and consequently impaired interpretability of the imaging material.
Recently fast multiphase contrast-enhanced sequences with artifact reduction by motion-insensitive radial acquisitions were introduced (1-3).
Long reconstruction times and necessity of an external reconstruction server limited clinical applicability of these approaches for older MR systems.
The purpose of this study is to compare the image quality of a prototypical Cartesian compressed-sensing (cs) accelerated free-breathing VIBE (fbVIBE) with clinically acceptable reconstruction time on the standard scanner HW (4) with that of a conventional breath-hold VIBE (bhVIBE) for dynamic contrast-enhanced imaging of the upper abdomen.
