What is the expected result in a successful Meckel's diverticulum scan?

• A. Absence of ectopic mucosa
• B. Presence of ectopic stomach mucosa
• C. Presence of virtual images
• D. Increase in blood flow

Answer: (B)

In a successful Meckel's diverticulum scan, the presence of ectopic stomach mucosa is the expected result. This condition arises when there is a remnant of gastric tissue located at the site of the Meckel's diverticulum, which is a congenital condition resulting from an incomplete obliteration of the omphalomesenteric duct during fetal development. In the nuclear medicine scan, a radiopharmaceutical, often technetium-99m (Tc-99m) labeled pertechnetate, is used because it localizes in areas of gastric mucosa. Thus, if ectopic gastric mucosa is present in the diverticulum, the radionuclide will accumulate there, leading to a positive scan result. This is a crucial diagnostic tool for identifying complications or abnormal tissues associated with the diverticulum. Understanding the nature of the scan helps to interpret the results correctly. While the other options address various aspects of imaging and physiology, they do not apply to the specific diagnostic outcomes of a Meckel's diverticulum scan in the context of identifying ectopic tissues.
