Transabdominal Gastric Contrast Ultrasound

Application Value of Transabdominal Gastric Contrast Ultrasound in the Diagnosis and Staging Evaluation of Gastric Cancer

In this study, the clinical data of patients diagnosed with gastric cancer who were ready for surgery were examined by contrast-enhanced ultrasonography and gastric-enhanced CT before surgery. Based on the results of postoperative pathological examinations, the diagnostic accuracy of gastric filling contrast-enhanced ultrasonography and gastric contrast-enhanced CT in different stages of gastric cancer was compared and analyzed. Provide better guidance for follow-up clinical practice.
