Eligibility
Inclusion criteria
Inclusion criteria: 1. Patients who underwent liver MR plain scan and dynamic enhanced scan in our hospital; 2. The image quality is clear, there are no serious artifacts, and it meets the diagnostic requirements; 3. The lesion has a definitive gold standard diagnostic result (any one of the following criteria shall be met): (1) Pathological diagnosis obtained via surgical resection or puncture biopsy; (2) Typical benign lesions (e.g., typical hemangioma, cyst) confirmed to be stable by imaging follow-up for >= 12 months; (3) Hepatocellular carcinoma (HCC) or metastatic tumors that have been comprehensively diagnosed clinically (combining tumor markers and imaging features), and whose lesion progression during follow-up conforms to the biological behavior of malignant tumors.
Exclusion criteria
Exclusion criteria: 1. Incomplete MR image sequence (missing key sequences in plainography, arterial phase, portal phase, delayed phase, or hepatobiliary phase); 2. Poor image quality, affecting AI model recognition or physician interpretation; 3. The maximum diameter of the lesion is < 5 mm, which is beyond the sensitive range of conventional AI detection; 4. Diffuse lesions of the liver (such as diffuse liver cancer) or lesion boundaries that cannot be clearly delineated.
