(a) Coefficient of variation (CV) for textural features in VOI 3 for T1-weighted spin-echo images with TR varying over the range 360–620 ms and shortest TE (TE = 3.4 ms). (b) Dependence of several textural features' CV on TE for T1-weighted spin-echo images with TR varying over the range 360–620 ms, showing the effect of admixing T2 weighting into the nominally T1-weighted image.
