研究目的: |
本研究的主要目的是开发一种基于磁共振(MR)成像的深度学习人工智能模型,以辅助鉴别诊断复杂的肝硬化结节与早期肝细胞癌结节 —— 这类结节在磁共振影像学上难以区分,但具有明确的病理诊断结果。 |
||||||||||||||||||||||
|
Objectives of Study: |
The main objective of this prospective study is to develop a deep learning AI model based on Magnetic Resonance (MR) imaging to assist in the differential diagnosis of complex cirrhotic and early-stage hepatocellular carcinoma nodules, which are difficult to distinguish on MR imaging but have distinct pathological diagnoses. |

||||||||||||||||||||||
|
Exclusion criteria: |
Exclusion criteria: 1. Liver MR images that do not meet the minimum quality requirements; 2. Patients with isolated cirrhotic nodules without other types of liver nodules or relevant imaging features; 3. Lack of contemporaneous clinical information or medical history close to the imaging time; 4. Presence of other major comorbidities that may interfere with liver disease assessment; 5. History of liver transplantation or major liver surgery; 6. Patients unwilling or unable to comply with follow-up procedures. |
