Ectopic gastric mucosal imaging

The positive rate of ectopic gastric mucosa imaging on ectopic gastric mucosa can reach 80%-85%. The image of the ectopic gastric mucosa is characterized by a radioactive abnormal concentration image with a fixed position in the esophagus or intestine at the same time as the stomach is developed. The subjects were fasted for more than 8 hours, and pentagastrin was injected intravenously 15 minutes before imaging to increase the uptake of 99TcmO4- by the ectopic gastric mucosa. After intravenous injection of 99TcmO4-, a was dynamically imaged at a speed of 5 min/frame for 60 min. Basic Information Specialist classification: Digestive examination classification: CT Applicable gender: whether men and women apply fasting: fasting Tips: Not suitable for people: those who are sensitive to radioactive elements. Normal value The stomach is well developed and the intestine is not developed, the kidney shadow is slightly present, the bladder shadow is getting thicker, and there is no fixed local radioactive concentration in the chest and abdomen. Clinical significance Abnormal results At the same time as the stomach is developed, a fixed radioactive abnormal concentration image appears in the esophagus or intestine. Patients with Meckel's diverticulum, intestinal duplication, and Barrett's esophagus need to be examined. Precautions Taboo before the examination: the subject is fasted for more than 8 hours. Indications during the examination: intravenous injection of pentagastrin 15 minutes before imaging to increase the uptake of 99TcmO4- in the ectopic gastric mucosa, can increase the detection rate. Inspection process The subjects were fasted for more than 8 hours, and pentagastrin was injected intravenously 15 minutes before imaging to increase the uptake of 99TcmO4- by the ectopic gastric mucosa. After intravenous injection of 99TcmO4-, a was dynamically imaged at a speed of 5 min/frame for 60 min. Not suitable for the crowd Unsuitable for people: those who are sensitive to radioactive elements.
