TI  - Combination of 2D sensitivity encoding and 2D partial fourier techniques for 
      improved acceleration in 3D contrast-enhanced MR angiography.
PG  - 16-22
AB  - Sensitivity encoding (SENSE) and partial Fourier (PF) techniques both reduce MRI 
      acquisition time. Two-dimensional SENSE uses coil sensitivities to unfold 
      aliasing in the phase/slice-encoding plane. One-dimensional PF and homodyne 
      reconstruction are routinely applied in the frequency/phase-encoding plane to 
      compensate for nonsampled k-space of the presumed real magnetization. Recently, a 
      modified 3D elliptical centric acquisition was proposed to facilitate 2D-PF and 
      homodyne reconstruction on an undersampled phase/slice-encoding plane. In this 
      work we hypothesized that this 2D-PF technique can be combined with 2D-SENSE to 
      achieve a greater acceleration factor than what each method can provide 
      separately. Reconstruction of data whereby SENSE and PF are applied along the 
      same axes is described. Contrast-enhanced MR angiography (CE-MRA) results from 
      experiments using four receiver coils in phantom and volunteer studies are shown. 
      In 11 volunteer studies, the SENSE-PF-homodyne technique using sevenfold 
      acceleration (4x SENSE, 1.7x PF) consistently provided high-diagnostic-quality 
      images with near 1-mm isotropic resolution in acquisition times of <20 s.
