Sensitivity of textural features to acquisition parameters has important clinical implications. The aim of this study is to investigate the effect of noise and resolution on textural features.

We compared textural features from a uniform and simulated texture, varied with noise, with experiment in a uniform phantom and organic texture.

Our data demonstrate that a uniform texture behaves as if it has inherent texture, due to presence of artefact, and this in turn will influence textural features as noise and acquisition parameters are varied.

We note that certain textural features used in clinical practice vary widely with image noise, whereas others appear to be robust.
