Tc-99m-Pertechnetate in Evaluation of Meckel's Diverticulum [Persian]

Meckel's diverticulum is a common congenital disorder which may result in Gl bleeding. For definite diagnosis before surgery, radiographic procedures such as small intestine barium studies are not greatly successful; on the other hand Tc-99m-Pertechnetate imaging is a physiologic and noninvasive method with high sensitivity and specificity. In this report, three patients with rectorrhagia, who had positive Tc-99m-Pertechnetate studies but otherwise negative evaluations, are presented. The usefulness of isotopic procedures in evaluation of Meckel's diverticulum is reviewed.
