delayed imaging for detection of meckel's diverticulum in tc-99m pertechnetate scintigraphy
Authors
abstract
tc-99m pertechnetate scintigraphy is the modality of choice for diagnosis of meckel's diverticulum. interpretation of meckel's scan identifies a focal area of radiopharmaceutical uptake in the anterior abdomen similar to normal gastric mucosa. the activity must be of the same pattern and intensity as gastric uptake. we present a 13-year-old patient with gastrointestinal bleeding and anemia. tc-99m pertechnetate scintigraphy was performed and initial images did not show any abnormal tracer activity in the abdomen. however, imaging continued and a focal activity was detected on the right side of the abdomen 60 minutes delayed image. follow laparascope operation the meckel's diverticulum was removed and the patient's symptoms disappeared completely. it is suggest to pay special attention to delayed images (60 minutes or beyond) especially when earlier images are negative.

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...
full textA jejunoileal duplication diagnosed by Tc-99m pertechnetate abdominal scintigraphy.
Alimentary tract duplications are uncommon congenital anomalies. Although most are symptomatic by the age of 2 years, some remain asymptomatic until adulthood. In one third of all cases, heterotopic gastric mucosa lines the wall of dupli cation, and may cause peptic ulceration, gastrointestinal bleed ing, fistulization or perforation. We report in this paper, a case of jejunoileal duplication...

Abdominal imaging after intravenous injection of 99mTc pertechnetate is a simple, safe, and noninvasive diagnostic procedure to show ectopic gastric mucosa, which is present in most cases of symptomatic Meckel's diverticulum. It was pe...
full textDramatic movement of a Meckel's diverticulum on Tc-99m pertechnetate imaging.
Tc-99m pertechnetate scintigraphy is a standard procedure for diagnosis of Meckel's diverticulum. It usually presents as a static abnormality in the midabdomen. We report a 17-year-old patient with severe lower gasterointestinal bleeding and anemia. On Tc-99m pertechnetate scintigraphy, focal abnormal activity was noted in the abdomen which was moving in the abdominal cavity. The patient underw...
