Advancement of 31P Magnetic Resonance Spectroscopy Using GRAPPA Reconstruction on a 3D Volume
The overall objective of this research is to improve currently available metabolic imaging techniques for clinical use in monitoring and predicting treatment response to radiation therapy in liver cancer. Liver metabolism correlates with inflammatory and neoplastic liver diseases, which alter the …

Entwicklung und Validierung eines MR-Flussphantoms für kontinuierlichen und pulsatilen Fluss sowie Evaluation zweier schneller 4D-Flusssequenzen
… vierdimensionalen MR-Flussmessungen – die 4D k-t GRAPPA-Technik –valide quantitative Untersuchungsergebnisse liefert. Des Weiteren sollte überprüft werden, ob diese Technik der beschleunigten parallelen Bildgebung es ermöglicht, vierdimensionale MR-Flussmessungen mit deutlich reduzierter Scanzeit, …

Accelerating magnetic resonance imaging by unifying sparse models and multiple receivers
… resolution, and signal-to-noise ratio (SNR). GRAPPA, an accelerated parallel imaging method, and compressed sensing (CS) have been successfully employed to accelerate the acquisition process by reducing the number of k-space samples required. GRAPPA leverages the different spatial weightings …

Ultra-high field (7T) magnetic resonance fingerprinting
… strategies to accelerate the 7T MRF sequence: GRAPPA and sliding-window radial undersampling. These are steps towards a clinically acceptable scan time for 7T MRF. Chapter 10 describes my work to understand the parallel transmit framework on our new 7T Terra scanner, culminating in a successful …
