Institutional review board statement: Following the ethical principles of the Declaration of Helsinki, we conducted a retrospective analysis of 237 patients diagnosed with hepatocellular carcinoma at the Affiliated Hospital of Youjiang Medical University for Nationalities from January 2019 to May 2024. We obtained approval from the Institutional Review Board and received a waiver of informed consent for all patients from the institution (No. YYFY-LL-2024-038).
Informed consent statement: In accordance with the Helsinki Declaration and our institution’s ethical review guidelines, the ethics committee granted a waiver of informed consent due to the non-interventional nature of the study and the de-identification of patient information.
Conflict-of-interest statement: The authors declare that they have no conflict of interest.

Core Tip
Core Tip: This study developed a 2.5-dimensional deep learning-based multi-instance learning (MIL) model (MIL signature) to predict microvascular invasion (MVI) in hepatocellular carcinoma (HCC) using computed tomography arterial phase images. The model outperformed traditional radiomics and clinical models, offering accurate MVI prediction and prognostic stratification for surgical resection and transcatheter arterial chemoembolization cohorts, supporting personalized HCC treatment.
