Radionuclide diagnosis of Meckel's diverticulum.

Meckel's diverticulum can be detected with a high degree of accuracy by radionuclide scintigraphy using technetium-99m pertechnetate. The technique is without risk and should precede roentgenographic studies when the diagnosis is suspected. The method is described and the causes for false positive and false negative examinations are discussed. False negatives are rare and false positive are usually secondary to other surgical entities. Overall accuracy is 85 to 90%.
