Temporal resolution and spatial resolution present competing demands in MRI. Several new techniques have been developed in recent years to accelerate MR image acquisition, some of which have been introduced commercially and others still in the research realm. This session will review some of these techniques. The first talk will provide an overview of the combined spin and gradient echo imaging (SAGE) technique and introduce spatial and temporal acceleration strategies for application in dynamic susceptibility contrast MRI and fMRI. This talk will also highlight the advantages of a multi-echo acquisition approach over the current clinical implementations. The second talk will discuss dynamic contrast-enhanced MRI reconstruction of undersampled k-space data using compressed sensing and deep learning.
1. Understand the basic implementation the SAGE pulse sequence
2. Understand the advantages of multi-echo acquisition vs. conventional EPI acquisition for DSC-MRI and fMRI
3. Understand the requirements of DCE-MRI in clinical practice
4. Discuss DCE-MRI reconstruction from undersampled k-space data using compressed sensing and deep learning methods
