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 gastrointest...

introduction: although pet scanning using f-18[fdg] is considered the superior radiotracer for tumnor imaging, gallium-67 is still in use for some malignancies such as lymphoma and hepatoma. one of the strategies to improve the diagnostic accuracy of gallium is to perform spect which is reported to be more sensitive compared to planar imaging. in this study we compared the sensitivity of spect ...

Multiple myeloma (MM) is a clonal B-lymphocyte neoplasm of terminally differentiated plasma cells. Imaging modalities which allow the recognition of the effects of myeloma cells on the skeletal system have been utilized for a long time. Herein, we represent a patient with generalized osteoporosis and hypercalcemia, who was referred for parathyroid scan, in whom the widespread bone marrow techne...

osteoma is a benign bone-forming tumor that usually arises in the craniofacial bones and rarely in the long bones. clavicular involvement is extremely rare. we report a 51-year-old woman with osteoma of the left clavicle. radiograph of the left shoulder showed a well-defined lobulated blastic mass in the proximal and mid-portion of the left clavicle. bone scintigraphy was performed 4 hours afte...

Background The ability to follow the distribution and migration of biologically active cells in human is essential for the development of cell-based therapies and diagnostics. Nuclear medicine imaging is widely applied in clinic as an attractive technique for in vivo WBC and stem cell tracking. The aim of this study was to evaluate prosthesis infection of a 51 years old man with previous histo...

Ubiquicidin (UBI) [29-41] is a synthetic cationic antimicrobial peptide that preferentially binds to bacterial cell membrane at the site of infection. We aimed to assess diagnostic value of 99mTc-UBI [29-41] as a radiopharmaceutical in differentiation of bacterial infection from sterile inflammation in suspected orthopedic implants. Nine patients suspected for orthopedic implant infection, all ...

A 65 years old male presented with abdominal pain (R.U.Q) and constipation, associated with weight loss and anorexia since 40 days prior to admission. Serum biochemical tests were normal. Colonoscopy showed hemorrhagic polypoid lesion in the cecum. Barium enema revealed filling defect in the cecum. Sonography revealed a target-shaped lesion (3cm×2.5cm) in upper segment of the right hepati...
