2-Deoxy-2-fluoro-d-glucose (FDG) is glucose analog routinely used in clinical and animal radiotracer studies to trace glucose uptake but it has rarely been used in plants. Previous studies analyzed FDG translocation and distribution pattern in plants and proposed that FDG could be used as a tracer for photoassimilates in plants. Elucidating FDG metabolism in plants is a crucial aspect for estab...

RATIONALE AND OBJECTIVES F18-fluorodeoxyglucose (FDG)-positron emission tomography (PET) studies have clinical value in suspected recurrent or metastatic colorectal cancer cases. Because this modality is not accessible for many patients, a camera-based FDG (CB-FDG) coincidence imaging was suggested as an alternative. Although inferior in resolution to a dedicated PET system, it can make FDG stu...

BACKGROUND Incidentally found thyroid lesions are frequently detected in patients undergoing FDG-PET/CT. The aim of this study was to investigate the prevalence of incidentally found thyroid lesions in patients undergoing FDG-PET/CT and determine the risk for thyroid cancer. METHODS FDG-PET/CT was performed on 3,379 patients for evaluation of suspected or known cancer or cancer screening with...

OBJECTIVE The purpose of our study was to evaluate the diagnostic accuracy of FDG positron emission tomography (PET) in comparison with CT in detecting recurrent ovarian carcinoma and its ability to reveal small tumor recurrence. MATERIALS AND METHODS We reviewed the records of 31 consecutive patients with pathologically proven epithelial carcinoma who underwent FDG PET 1 month before second-...

Neuroendocrine tumors (NETs) are relatively rare and heterogeneous, mostly asymptomatic discovered incidentally. PET-CT is one of the gold diagnostic standards typically detects well-differentiated NETs using 68Gallium-Dotatate (Ga-PET/CT) more aggressive undifferentiated 18F-FDG (FDG-PET/CT). However, some displaying atypical high-grade features being detected on FDG-PET/CT. In this study, we ...

Herein, we report the F-18 fluorodeoxyglucose (18F-FDG) positron emission tomography (PET)/computed tomography (CT) findings of a benign solitary fibrous tumor (SFT) of the kidney. The patient was a 63-year-old woman with a mass in the right kidney (10×9.7 cm), incidentally found on CT images. The CT scan showed a lobulated tumor arising from the hilum of the right kidney. The tumor consisted o...

 Carcinosarcoma is a rare type of cancer that is composed of a mixture of sarcomatous and carcinomatous elements. Pulmonary carcinosarcoma has a 25% five-year survival rate with a prognosis poorer than other non-small cell lung carcinomas. Herein, we report a case of pulmonary carcinosarcoma and its 18F-FDG PET/CT findings. A 61-year-old male patient presented with brain symptoms, including hea...

objective: resistance of metastatic lymph nodes (lns) to high dose i-131 therapy is associated with high morbidity in patients with differentiated thyroid cancer. we evaluated the role of f-18 fdg pet/ct in the prediction of resistance to high dose i-131 therapy in patients with papillary thyroid cancer. methods: the subjects were 307 patients who underwent total or near total thyroidectomy fol...

We report a case of an 85-year-old woman with a foreign-body granuloma which accumulated 18F-fluorodeoxyglucose (FDG). Unenhanced computed tomography showed a hyperdense mass with a hypodense rim in the right subphrenic space. FDG PET/CT images showed intense FDG uptake in the hypodense rim and little FDG uptake in the center of the mass, showing a ring-shaped appearance. The fusion imaging of ...

18F-fluorodeoxyglucose ([18F]-FDG) positron emission tomography/computed tomography (PET/CT) is a useful functional image technique to evaluate the disease extent in many cancers, as well differentiate benign from malignant metastasis. We report case of 49-year-old woman with breast cancer and suspected lung metastasis by conventional images. After FDG-PET/CT demonstrating faint, or even no FDG...
