Research Progress on the Application of Radiomics and Deep Learning in Liver Fibrosis
Liver fibrosis (LF) is a critical intermediate stage in liver disease progression. Early and accurate diagnosis is vital, but traditional liver biopsy has limitations. Radiomics and Deep Learning (DL) offer non-invasive diagnostic tools with significant potential. This review summarizes advancements in radiomics and DL for LF diagnosis, staging, prognosis, and etiological differentiation across MRI, CT, and ultrasound. Despite challenges in generalization, standardization, interpretability, and multimodal fusion, these AI technologies promise to integrate clinical monitoring methods, overcome early LF diagnosis obstacles, and advance precision medicine.

| Category | Radiomics | Deep Learning |
|---|---|---|
| Generation Mechanism | Feature Engineering: Mathematically defined formulas designed by experts to quantify specific patterns (e.g., heterogeneity). | Feature Learning: Automatically discovered hierarchical representations via backpropagation, optimized for the specific task. |
| Feature Complexity | Explicit & Fixed: Ranging from simple morphological (shape, volume) to complex transformed features (Wavelet, Laplacian of Gaussian). | Hierarchical & Abstract: Progressing from low-level edges/textures to high-level semantic patterns (e.g., nodular surface, distorted boundaries). |
| Interpretability Status |
|
|
| Workflow Dependency | Heavily dependent on precise ROI segmentation and standardization of image acquisition/reconstruction. | Less dependent on manual segmentation (end-to-end); can utilize whole-volume inputs but requires large-scale data for robustness. |

AUC for SVM model in MRI-based LF prediction (training set)
MRI Radiomics for Hepatitis B-related Fibrosis Prognosis
A study utilized MRI-based radiomics to effectively predict the risk of liver-related events, including ascites, variceal bleeding, hepatorenal syndrome, hepatic encephalopathy, and hepatocellular carcinoma in patients with hepatitis B virus-related fibrosis. This approach leverages SHapley additive explanations (SHAP) to understand heterogeneity in liver fibrosis tissue, informing decision-making for treatment.
Key Takeaway: MRI radiomics, combined with machine learning, significantly enhances prognostic prediction for LF patients, offering objective insights beyond traditional clinical indicators.

AUC for DL network in CT-based LF staging (significant fibrosis F2-F4)
DL-Based CT for Liver Fibrosis Staging
Researchers used portal phase enhanced CT images from 252 patients to construct a fibrosis staging network. By using gradient-weighted class activation mapping, focal areas relevant to staging were highlighted. The network achieved high AUC values for different fibrosis stages, with emphasis shifting from liver surface (F0) to parenchymal regions (F4).
Key Takeaway: DL algorithms applied to contrast-enhanced CT images provide a standardized and quantitative tool for LF staging, particularly useful for characterizing advanced fibrosis.
