Table shows ICC statistics of the consistency of whole-brain white matter ePVS quantification using SR T2w, Reg T2w, and T1w only, as compared with the silver standard with 3D T2.
3D, three-dimensional; CI, confidence interval; ePVS, enlarged perivascular space; ICC, intraclass correlation coefficient; PVS, perivascular space; Reg T2w, sinc-interpolated 2D T2w; SR, super-resolution; T1w, T1-weighted; T2w, T2-weighted.
