Background: To retrospectively describe imaging characteristics of liver metastases on fused FDG-PET/ MRI data sets and to compare the diagnostic accuracy of MRI and fused FDG-PET/MRI data sets for the detection of liver metastases in patients undergoing systemic anticancer treatment. Materials and Methods: 43 oncological patients (mean age: 56+/- 11 years) were investigated by FDG-PET...
OBJECTIVE The aim of this study was to evaluate the diagnostic accuracy of positron emission tomography/computed tomography with (18)F-fludeoxyglucose (FDG-PET/CT) in a population with suspected graft infection and to validate a new diagnostic imaging score for FDG-PET/CT. METHODS This was a prospective cohort study. FDG-PET/CT was performed prospectively in 34 patients with suspected graft i...
results thirty-four patients were hyperglycemic and 127 non diabetic. sensitivity, specificity, positive predictive value and negative predictive value of fdg-pet/ct were 90%, 88%, 87% and 91% in non diabetic and 82%, 92%, 95% and 73% in hyperglycemic patients, respectively. overall, the accuracy was higher in non diabetic than hyperglycemic patients (89% vs. 85%). conclusions accuracy of fdg-p...
BACKGROUND F-fluorodeoxyglucose (FDG) positron emission tomography (PET) is a promising modality for detecting active lesions of cardiac sarcoidosis (CS). However, determining whether 18F-FDG uptake in the myocardium is physiological is challenging due to metabolic shift in myocardial cells. Although methods for inhibiting physiological myocardial 18F-FDG uptake have been proposed, no standard ...
Detection of extranodal spread in head and neck cancer with [18F]FDG PET and MRI: improved accuracy?
AIM Preoperative detection of extranodal spread (ENS) in head and neck cancer can have important consequences for patient management. The aim of this study was to determine whether 18-fluorodeoxyglucose positron emission tomography ([18F]FDG PET) or a combination with Magnetic Resonance Imaging (MRI) could more accurately predict ENS, especially with the near availability of fully integrated [1...
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): 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET-CT) is a well-used and established technique for lung cancer staging. Radiation therapy requires accurate target volume delineation, which is difficult in most cases due to coexisting atelectasis. The present study was performed to compare the 18F-FDG PET-CT with contrast enhanced computed tomogr...
FDG-PET, combined with CT, is nowadays getting more and more relevant for the diagnosis of several infectious and inflammatory diseases and particularly for therapy monitoring. Thus, this paper gives special attention to the role of FDG-PET/CT in the diagnosis and therapy monitoring of infectious and inflammatory diseases. Enough evidence in the literature already exists about the usefulness of...
background: despite the relative success of surgical resection followed by proton, proton/photon, or conventional radiotherapy in terms of recurrence-free survival, chordomas are still associated with a high rate of recurrence. to our knowledge there are only very few reported cases of this rare tumor detected by f-18 fdg-pet. materials and methods: in this case we show the significance of f-18...
background: to retrospectively describe imaging characteristics of liver metastases on fused fdg-pet/ mri data sets and to compare the diagnostic accuracy of mri and fused fdg-pet/mri data sets for the detection of liver metastases in patients undergoing systemic anticancer treatment. materials and methods: 43 oncological patients (mean age: 56+/- 11 years) were investigated by fdg-pet/ct and l...
