Similar Appearance on Dynamic Images of Meckel Scintigraphy Caused by Different Etiologies

Abstract

Positive gastric mucosa Meckel diverticulum generally shows nonmoving activity in the right abdomen, which appears early in the study at about the same time of the appearance of the stomach. However, a stoma from ileostomy can result in similar findings on dynamic images. The difference between a true Meckel diverticulum and stoma can be exposed by lateral views.

Menstruation Confounding the Correct Interpretation of 99mTc-RBC Bleeding Scan

“…Surgical pathology confirmed the diagnosis of ectopic gastric mucosa. Although false-positive interpretations of 99m TcO 4− Meckel scintigraphy also occur,5,6 the application of SPECT/CT, as in our case, can improve the diagnostic accuracy of test 7. Uterus uptake during menstruation in other nuclear medicine modalities has also been reported previously, including18 F-FDG, 8 68 Ga-FAPI, 9 99m Tc-Mag3, 123 I-MIBG, 10 and 131 I 11.…”

Excreted 99mTc-Pertechnetate in a Renal Pelvis as a Potential False Positive in a Meckel’s Scan

“…SPECT/CT images can be acquired to help localize a focus of radiotracer uptake seen on planar imaging 8,9 . It is also important to consider nonpathologic causes of radiotracer uptake including anatomic variants 10–15 . Although not routinely performed, SPECT/CT can help confirm or refute the diagnosis of a Meckel’s diverticulum.…”
