Lymph node disease in 2-deoxy-2-fluorodeoxyglucose positron emission tomography/computed tomography imaging: Advances in artificial intelligence-driven automatic segmentation and precise diagnosis

Imaging evaluation of lymph node metastasis and infiltration faces problems such as low artificial outline efficiency and insufficient consistency. Deep learning technology based on convolutional neural networks has greatly improved the technical effect of radiomics in lymph node pathological characteristics analysis and efficacy monitoring through automatic lymph node detection, precise segmentation and three-dimensional reconstruction algorithms. This review focuses on the automatic lymph node segmentation model, treatment response prediction algorithm and benign and malignant differential diagnosis system for multimodal imaging, in order to provide a basis for further research on artificial intelligence to assist lymph node disease management and clinical decision-making, and provide a reference for promoting the construction of a system for accurate diagnosis, personalized treatment and prognostic evaluation of lymph node-related diseases.
