Abstract
The ability to detect Meckel's diverticulumwith conventional radiographic methods is usually quite uncertain. The concentration of 99m TcNa pertechnetate by gastric parietal cells has been used effectively to detect the presence of gastric mucosa in these ectopic sites. In addition, several cases of intussusception and small bowel obstruction have been demonstrated with radiopertechnetate and abdominal imaging. It is believed that the radiopertechnetate is concentrated in the edematous interstitial fluid associated with such obstructive lesions, where a compromise of the vascular supply exists. The use of this nonspecific test has so far been very limited. Its reliability, and role in the evaluation of difficult diagnoses of the abdomen can only be clearly defined with further clinical experience. This brief report is included to acquaint the reader with an area of potential future development.
