UNLABELLED Gastrointestinal stromal tumors (GISTs) are gaining the interest of researchers because of impressive metabolic response to the targeted molecular therapeutic drug imatinib mesylate. Initial reports suggest an impressive role for (18)F-FDG PET in follow-up of therapy for these tumors. However, the role of (18)F-FDG PET versus that of CT has not been established. Therefore, we compare...

This study reports a comparison of Fluorine-18 deoxyglucose positron emission tomography (FDG-PET) and O-15 water (H2(15)O) PET with regard to lateralization of the seizure focus in patients with complex partial epilepsy. The analysis of 35 patients who had an anterior temporal lobectomy for medically intractable seizures indicated that FDG- and H2(15)O-PET were highly correlated in demonstrati...

Positron emission tomography (PET) imaging using (18)F-2-deoxy-D-glucose, a D-glucose analog labeled with fluorine-18 (FDG-PET), is being evaluated in the assessment of prognosis and therapeutic response in patients with non-small cell lung cancer. FDG-PET imaging has the potential to allow more appropriate selection of patients for surgical resection and for neoadjuvant and aduvant chemotherap...

Computed tomography (CT) is currently the most commonly used means for staging malignant lymphoma. 18F-fluoro-2-deoxyglucose positron emission tomography (FDG-PET), FDG-PET/CT fusion, and whole-body magnetic resonance imaging (WB-MRI) are potential alternatives. The purpose of this study was to systematically review published data on the diagnostic performance of CT, FDG-PET, FDG-PET/CT fusion,...

BACKGROUND The purpose was the comparison of positron emission tomography using F-18-fluorodeoxy-glucose (FDG-PET) and spiral thoracic CT to detect pulmonary metastases from malignant primary osseous tumors. PATIENTS AND METHODS In 71 patients with histologically confirmed malignant primary bone tumors (32 osteosarcomas, 39 Ewing's sarcomas) 111 FDG-PET examinations were evaluated with regard...

BACKGROUND The purpose of this study was to combine intraoperative gamma probe (GP) detection with preoperative fluorine 18-fluoro-2-deoxy-glucose positron emission tomography (18F FDG-PET) imaging in order to improve detection of tumor recurrence in colorectal cancer (CRC) patients. METHODS Twenty-one patients (12 females, 9 males) with a mean age of 54 years (range 31-78) were enrolled. Pat...

The aim of this retrospective analysis was to describe our clinical experience for fluorine-18 (F) fluorodeoxglucose (FDG) positron emission tomography/computed tomography (PET/CT) in patients with soft tissue and osseous sarcoma. Total of 26 F-FDG PET/CT scans were evaluated in 17 patients (7 osteosarcoma, 5 Ewing’s sarcoma, 3 uterine sarcoma and 2 rhabdomyosarcoma) in different stages of dise...

UNLABELLED Functional techniques are playing a pivotal role in the imaging of cancer today. Our aim was to compare, on a head-to-head basis, 3 functional imaging techniques in patients with histologically verified neuroendocrine tumors: somatostatin receptor scintigraphy (SRS) with (111)In-diethylenetriaminepentaacetic acid-octreotide, scintigraphy with (123)I-metaiodobenzylguanidine (MIBG), an...

Introduction: In intensity-modulated radiation therapy (IMRT) planning for nasopharyngeal carcinoma (NPC), cervical lymph nodes (CLNs) that appear negative on magnetic resonance imaging (MRI) scans can be difficult to target. The purpose of this study was to assess the advantage of 18F-fluorodeoxyglucose positron emission tomography with computed tomography (18F-FDG PET/CT) for distinguishing M...

BACKGROUND/AIMS 18F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) has been used for preoperative staging of colorectal cancer (CRC). However, the diagnostic accuracy of FDG-PET/CT for detection of lymph node or distant metastasis and its prognostic role have not been well established. We therefore evaluated the diagnostic and prognostic value of FDG-PET/CT in ...
