Gastric emptying measurement and imaging

Gastric emptying measurement and imaging were used to find out the cause of gastric dysfunction, and the efficacy of gastric motility drugs was observed. After oral administration of an imaging agent that is not absorbed or adsorbed by the gastric mucosa, it is discharged into the intestine by gastric peristalsis, and the gastric emptying time can be calculated from the decrease in radioactivity in the stomach to understand the motor function of the stomach. Basic Information Specialist classification: Digestive examination classification: ultrasound Applicable gender: whether men and women apply fasting: fasting Tips: cooperate with the doctor. Normal value The outline of the stomach is clear, the semi-empty time of the solid food stomach is 76-108 min, and the semi-empty time of the liquid food stomach is 9-15 min. Clinical significance Abnormal results: duodenal ulcer, atrophic gastritis, Zollinger-Ellison syndrome, Chagas disease, pancreatic insufficiency, and hyperthyroidism. People who need to be examined: patients with abdominal pain. Precautions Taboo before inspection: eating. Requirements for inspection: cooperate with the doctor. Inspection process After oral administration of an imaging agent that is not absorbed or adsorbed by the gastric mucosa, it is discharged into the intestine by gastric peristalsis, and the gastric emptying time can be calculated from the decrease in radioactivity in the stomach to understand the motor function of the stomach. The developer is a solid or liquid test meal prepared from 99Tcm-SC or 99Tcm-DTPA. The subjects were fasted for 12 hours, and all the solid or liquid test meals were eaten within 5 minutes, and collected at a speed of 1 frame/5 min for 2 hours, and the food stomach half emptying time was calculated by ROI technique. Not suitable for the crowd A patient who responds to an imaging agent. Adverse reactions and risks No complications.
