Transabdominal Gastric Contrast Ultrasound
Conditions
Brief summary
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.
Interventions
DIAGNOSTIC_TESTgastric contrast ultrasound
Gastric contrast ultrasound (GCUS) refers to that the patient fills the stomach cavity with oral water, contrast agent and ultrasound contrast agent before the examination to remove the gas in the stomach cavity and fill the stomach cavity to become a homogeneous echo area and form a good acoustic sound. Interface contrast, more clearly showing the gastric wall hierarchy and the ultrasound examination method of the lesions. In this way, not only the changes of the gastrointestinal mucosa can be found, but also the submucosal tumors of the gastrointestinal tract can be clearly displayed, the internal structural characteristics of the tumor, the extent of the lesions, the depth of infiltration, the TNM staging of the tumor, and the lesions of the surrounding organs can be displayed.
