title: [Scintigraphic diagnosis of Meckel's diverticulum using Tc-99m-pertechnetate].
abstract: Meckel's diverticulum (MD) is a well-known cause of lower gastrointestinal hemorrhage, particularly in the pediatric age group. The radionuclide 99mTc-pertechnetate has been found useful in visualizing MD which contain gastric mucosa. This test is predicated of the affinity of the isotope for the parietal cells of the gastric glands. In an attempt to evaluate the sensibility and specificity of pertechnetate, the clinical data and scintigrams of 27 patients with suspected MD were reviewed. The scintigram correctly identified MD before operation in 6 of 7 patients. The false negative study occurred in a MD without gastric mucosa.
