Fast imaging techniques such as echo planar imaging (EPI)
are popular techniques for imaging of neuronal injuries.
However, there is an inherent problem with these
techniques with respect to susceptibility and geometric
artifacts that distort not only anatomical information
but also the quantification of relevant quantities, such
as water diffusion. To provide robust and fast
acquisitions at high field, this study utilizes an
ultrafast single-shot spatiotemporally encoded (SPEN)
imaging sequence with diffusion encoding to measure
apparent diffusion coefficient (ADC) in stroke. Results
show that SPEN images provide a more accurate way of
measuring ADC at high field compared to EPI.
