Multi-modal sequences

Multi-modal MRI techniques – able to sample wider parameter ranges and to capture dynamic process – are at the key of my method developments.

ZEBRA: One of our recent developments is a novel acquisition technique allowing to sample data for joint diffusion-relaxometry in an efficient way. This technique builds on a prior development (interleaved diffusion) to allow sampling the parameter space (diffusion encoding, inversion time TI and echo time TE) with high efficiency and flexibility.

Data is available open source and was used for the CDMRI challenge MUDI2019 and the CDMRI challenge SuperMUDI2020.

PERFOX: Velocity-selective Arterial Spin Labeling in combination with T2* relaxometry offers simultaneous assessment of oxygenation and perfusion – we use it e.g. in the placenta to study dynamic processes.
