From: Liver fibrosis stage classification in stacked microvascular images based on deep learning
Comparison of the representative stacked microvascular images in different fibrosis stages. With the development of fibrosis, complex modifications of the vessels occur such as narrowing, caliber irregularities, and tortuosity. The scores for each fibrosis stage are as follows in order of narrowing, irregular caliber, and tortuosity: a F0-1Low. 0, 0, and 0 points, b H0-1High. 2, 0, and 0 points, c F2. 2, 1, and 0 points, d F3. 2, 1, and 1 points, e F4. 2, 2, and 2 points, respectively
