MRI diffusion tensor reconstruction with PROPELLER data acquisition

MRI diffusion imaging is effective in measuring the diffusion tensor in brain, cardiac, liver, and spinal lesion imaging. Diffusion tensor tomography MRI (DTT MRI) method is based on reconstructing tensor field from measurements of projections of the diffusion tensor field. In the present paper we examine the potential of a novel data acquisition scheme, PROPELLER (Periodically Rotated Overlapping ParallEL Lines with Enhanced Reconstruction), for its imaging capability and sufficiency for diffusion imaging. DTT MRI with PROPELLER data acquisition shows the significant potential to reduce a number of weighted measurements, avoid an ambiguity in reconstructing diffusion tensor parameters, increase SNR and decrease the influence of signal distortions.
