Research Abstract	Texture analysis of 3-T MR images of the liver using artificial neural network (ANN) was a useful method for the non-invasive evaluation of hepatic fibrosis or cirrhosis. To select appropriate sizes of region of interests (ROIs) may improve the diagnostic performances of hepatic fibrosis.
