SLICE-SELECTIVE ADIABATIC MAGNETIZATION PREPARATION (SAMPA) FOR T2-WEIGHTED AND DIFFUSION-WEIGHTED IMAGING
Magnetic resonance (MR) imaging at high-fields (3-4.7T) and ultra-high fields (7T and above) leads to higher signal levels with improved image quality, but physical limitations still prevent these systems from being highly efficient. The gold standard for an important MRI method such …
SEMI-ADIABATIC SPECTRAL-SPATIAL SPECTROSCOPIC IMAGING (SASSI)
Proton magnetic resonance spectroscopic imaging (MRSI) can be used as a non-invasive technique for a variety of procedures such as differentiating radiation damage from brain tumors post-therapy, categorizing brain tumors, or investigating neurological and psychiatric diseases like Alzheimer’s and Parkinson’s Disease. However, …
MATCHED-PHASE SEMI-ADIABATIC MULTI-SLICE SPIN-ECHO PINS PULSE PAIR
There are still several challenges in acquiring high-quality MR images when using high magnetic field systems, such as the 7 Tesla. Three key issues prevent these systems from functioning at their highest potential: (1) nonuniformities in signal and contrast due to increased …
