| For Gastric cancer is a malignant tumor with a high global mortality rate. Early diagnosis and accurate staging are essential for optimizing therapeutic strategies and improving patient prognosis. In recent years, ultrasound diagnostic technology has garnered increasing attention in the screening, diagnosis, and staging of gastric cancer due to its unique advantages, including being non-invasive, radiation-free, and capable of real-time dynamic observation. In particular, transabdominal ultrasound (TAUS), endoscopic ultrasound (EUS), and contrast-enhanced ultrasound (CEUS) have demonstrated significant potential in enhancing diagnostic accuracy and guiding clinical management. Despite substantial progress in the application of ultrasound technology for gastric cancer, certain technical limitations and clinical challenges persist. This paper systematically reviews the primary ultrasound diagnostic methods for gastric cancer, evaluates the clinical value and limitations of various ultrasound techniques, and aims to provide a theoretical basis and technical support for the early identification and personalized treatment of gastric cancer. |
