Core Tip

Core tip: Artificial intelligence (AI) is widely used and gaining in popularity in the medical imaging of the liver. AI can achieve an increased accuracy for diagnosis with higher efficiency and greatly reduce the physicians’ workload. This article illustrates basic technical knowledge about AI, including traditional machine learning algorithms and deep learning algorithms, especially convolutional neural networks, and their clinical application in the medical imaging of liver diseases. Lastly, we discuss the challenges and future directions of clinical application of deep learning techniques.
