Concentrations of the naturally occurring alpha-emitting radioelements, radium-226, radium-228, and lead-210, and of stable lead and fluorine were determined in bone specimens from 32 individuals having a verified osteogenic sarcoma. Comparison of these results with those for the average person
OBJECTIVE
We reviewed the medical literature on the application of fluorine-18-fluorodeoxyglucose positron emission tomography ((18)F-FDG PET) imaging in the management of uterine sarcomas and presented the results in systematic review and meta-analysis format.
METHODS
Medline, SCOPUS, and ISI Web
Pulmonary artery sarcoma (PAS), although rare, must be considered in the differential diagnosis of pulmonary thromboembolism (PTE). This tumor is highly malignant and the prognosis is very poor. As much as the standardized uptake values (SUVs) at fluorine-18 fluorodeoxyglucose positron emission
Positron emission tomography (PET) imaging has a growing role as an imaging modality to be used in conjunction with magnetic resonance and computed tomographic imaging in the detection, staging, and management of many sarcomas and carcinomas. Since PET is a relatively new modality and the incidence
Sarcomas are a heterogeneous group of tumors comprising approximately 1% of all malignancies. Definitive treatment of sarcoma is surgical resection. However, after surgical removal, 40% to 60% of the patients will develop local or distant recurrence. Therefore, the early detection and treatment of
To investigate the performance of fluorine-18-fluorodeoxyglucose (F-FDG) positron emission tomography (PET) and PET/computed tomography (CT) in the diagnosis, staging, restaging, and recurrence surveillance of bone sarcoma by systematically reviewing and meta-analyzing the published literature.To
OBJECTIVE
The aim of this retrospective study was to determine whether glucose metabolism assessed by using Fluorine-18 (F-18) fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) provides prognostic information independent of established prognostic factors in patients
OBJECTIVE
Metabolic volumetry and heterogeneity indexes are increasingly being used in fluorine-18 fluorodeoxyglucose (F-FDG) PET, mostly using isocontour methods. However, there is no standard method to determine optimal margin thresholds for isocontour volume of interest (VOIiso). Here, VOIiso
BACKGROUND
The usefulness of positron emission tomography (PET) with fluorine-deoxyglucose (FDG) in sarcomas and non-sarcoma non-epithelial (NSNE) tumors is not clearly defined.
OBJECTIVE
To report a Chilean experience with NSNE tumors evaluated using PET with FDG.
METHODS
Retrospective review of
PET with 18F-fluoro-2-deoxy-D-glucose (FDG) was used to study soft-tissue lesions. The goals of the study were to establish FDG uptake in soft-tissue sarcoma, to determine the sensitivity of this technique, to investigate the correlation between histologic grade and glucose consumption and to
We compared the diagnostic accuracy of [18F]FDG PET and 99mTc-MIBI SPECT in musculoskeletal sarcomas.
METHODS
Forty-eight patients with clinically suspected recurrent or residual musculoskeletal sarcomas were examined with both FDG-PET and MIBI-SPECT within 2 wk of each study (one follow-up study in
The purpose of this study was to investigate the potential role of FDG-PET in the monitoring of neoadjuvant therapy of soft-tissue and musculoskeletal sarcomas.
METHODS
Nine patients were studied. Neoadjuvant therapy consisted of either chemotherapy or combined radiotherapy and hyperthermia. The
OBJECTIVE
To retrospectively compare the diagnostic accuracy of positron emission tomography (PET)/computed tomography (CT), PET, conventional imaging, and combined PET/CT and conventional imaging for tumor staging of bone and soft-tissue sarcomas, by using histologic or follow-up imaging findings
Positron emission tomography (PET) using 2-deoxy-2-[(18)F] fluoro-D-glucose ((18)F-FDG) has been used with increased frequency in the care of patients with soft tissue sarcomas to predict malignant potential of tumours, prognosis of survival and response to chemotherapy. Although there are several
METHODS
The treatment of a patient with soft-tissue sarcoma was evaluated with FDG-PET. A limb-saving complete remission of a locally advanced liposarcoma of the left thigh was achieved with isolated regional perfusion of the limb with tumor necrosis factor alpha, interferon gamma and
