background: positron emission tomography (pet) scan is a non-invasive, complicated and expensive medical imaging technology used for diagnosis and treatment of various diseases including cancers. this study aimed to evaluate the safety and effectiveness of this technology in iran. methods: the major medical electronic databases including cochrane library, google scholar, medline and iranmedex w...

Objective(s): In this study, we aimed to describe the characteristics of portal vein tumor thrombosis (PVTT), complicating hepatocellular carcinoma (HCC) in contrast-enhanced FDG PET/CT scan. Methods: In this retrospective study, 9 HCC patients with FDG-avid PVTT were diagnosed by contrast-enhanced fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT), which is a comb...

objective(s): in clinical practice, approximately 10-25% of post-surgical differentiated thyroid carcinoma (dtc) patients with high serum thyroglobulin (tg) and negative 131i whole-body scan (wbs) have poor prognosis due to recurrent or metastatic lesions after radioactive iodine treatment. the purpose of this study was to evaluate the value of 18f-fdg pet/ct scan in dtc patients with high seru...

FDG PET CT scan is considered to be a sensitive tool to detect skeletal metastasis in known malignancies. However, it’s high sensitivity and low specificity may account for false positive diagnosis in cases of trauma, infection, inflammation and other benign conditions. Skeletal hemangioma is one of the common benign conditions which are typically ametabolic on FDG PET CT with no uptake on bone...

Objective(s): In clinical practice, approximately 10-25% of post-surgical differentiated thyroid carcinoma (DTC) patients with high serum thyroglobulin (Tg) and negative 131I whole-body scan (WBS) have poor prognosis due to recurrent or metastatic lesions after radioactive iodine treatment. The purpose of this study was to evaluate the value of 18F-FDG PET/CT scan in DTC patients with high seru...

objective(s): in this study, we aimed to describe the characteristics of portal vein tumor thrombosis (pvtt), complicating hepatocellular carcinoma (hcc) in contrast-enhanced fdg pet/ct scan. methods: in this retrospective study, 9 hcc patients with fdg-avid pvtt were diagnosed by contrast-enhanced fluorodeoxyglucose positron emission tomography/computed tomography (fdg pet/ct), which is a comb...

conclusion the technical performance of pet scan is significantly higher than similar technologies for staging and treatment of nsclc. in addition, it might slightly improve the treatment process and lead to a small level of increase in the quality adjusted life year (qaly) gained by these patients making it cost-effective for the treatment of nsclc. results the total annual running cost of a p...

b-cell lymphoblastic lymphoma (b-lbl) is an uncommon subtype of pediatric non-hodgkin lymphoma (nhl) which rarely involves the skin primarily. the positron emission tomography with 2-deoxy-2-[fluorine- 18] fluoro-d: -glucose integrated with computed tomography (18f-fdg pet/ct) scan findings of a 8-year-old boy with cutaneous b-lbl were presented. pet/ct scan demonstrated mild fdg uptake in the ...

We describe a patient with newly diagnosed limy cancer. Staging was performed with CT and mediastinoscopy. FDG PET scan was performed and confirmed increased metabolic activity in the primary tumor as well as the hilar lymph node. Seven months after initial presentation, the patient was found to have two lytic lesions in the pelvis on plain radiograph. Hone scan was negative but PET demon...
