QIBA DWI phantom. Photograph of shows 13 vials containing PVP within the phantom, with PVP concentrations of 0%, 10%, 20%, 30%, 40%, and 50% (a). The b = 1,000 s/mm2 images of the phantom acquired with AP-DWI (b), B0-corrected-DWI (c), and RDC-DWI (d) are shown. Compared with AP-DWI and B0-corrected-DWI, RDC-DWI shows the least distortion and fewest susceptibility artifacts (b, c, and d, arrows). Air contamination is observed in one of the 50% PVP vials (b, c, and d, arrowheads). AP, Anterior-posterior; DWI, Diffusion-weighted imaging; PVP, Polymerpolyvinylpyrrolidone; QIBA, Quantitative Imaging Biomarkers Alliance; RDC-DWI, Reverse encoding distortion correction DWI
