| Zusammenfassung | Dynamic Contrast Enhanced (DCE) MRI of the liver is an important diagnostic tool. The main challenge is complex respiratory motion of the abdomen. Here we present a motion correction approach for DCE-MRI. Golden Radial Phase Encoding data was acquired continuously in a patient after contrast injection during free-breathing. In a first step, non-rigid respiratory motion was estimated from the data. The motion information was then used to reconstruct 3D motion corrected dynamic images with a temporal resolution of 13s and an isotropic spatial resolution of 1.5mm3. The proposed technique strongly reduced motion artefacts and ensured high image quality. |
