Computed tomography-based deep learning and multi-instance learning for predicting microvascular invasion and prognosis in hepatocellular carcinoma

Figure 1 Study population and workflow. MVI: Microvascular invasion; CT: Computed tomography; HCC: Hepatocellular carcinoma; ROI: Region of interest; CNN: Convolutional neural network; PLH: Predictive likelihood histogram; BoW: Bag-of-word; TF-IDF: Term frequency-inverse document frequency; MLP: Multilayer perceptron; AUC: Area under the curve; DCA: Decision curve analysis; RFS: Recurrence-free survival; PFS: Progression-free survival.
