[The upper gastrointestinal imaging and the gastrogram using 99mTc-pertechnetate (author's transl)].
99mTc-pertechnetate was used for the diagnoses of the upper gastrointestinal tract. Oral administration was useful for the detection of the stenosis and obstruction on the esophagus and the pylorus to the poor risk patients. Mucosal imaging of the stomach was clearly revealed by intravenous administration, and the scintigram of the patient with stomach cancer showed a cold region. Taking the gastric scintiphoto, temporal radioactivity in the stomach region was recorded (gastrogram). This seems to be a new and prospective approach to the clinical gastroenterology.
