TPI-SENSE for Fast Ultra-Short TE MRI

This study demonstrates the combination of twisted projection imaging (TPI) with sensitivity encoding (SENSE) parallel imaging as a means to further accelerate data acquisition in ultra-short TE MRI. Studies on computer models and phantoms were performed with projection reductions in polar (ring) direction and azimuthal (rotation) direction. Both simulation and phantom images reconstructed from the undersampled data sets illustrated that the TPI sampling scheme, due to its inherent 3D nature, can tolerate larger reduction factors than comparable 2D sampling schemes.
