www.onk.ns.ac.rs/Archive Vol 20, No. 3-4, December 2012 PET IMAGING IN ESOPHAGEAL CARCINOMA Esophageal carcinoma is a relatively rare disease with approximately 13,200 new cases detected in 2001 in the United States (1). It is most common between 50 and 60 years of age with a male to female ratio of 4:1 (2). According to the SEER database, an annual age-adjusted incidence rate is 4.5 per 100,00...
PURPOSE To determine the value of diffusion-weighted MRI (DWI-MRI) for pretherapeutic imaging of fluorodeoxyglucose (FDG)-avid lymphoma and lymphoma with variable FDG avidity. EXPERIMENTAL DESIGN Treatment-naïve patients with lymphoma who were referred for whole-body staging were included in this prospective study. Group A included patients with FDG-avid lymphoma (e.g., Hodgkin, diffuse large...
Head movement during a dynamic brain PET/CT imaging results in mismatch between CT and dynamic PET images. It can cause artifacts in CT-based attenuation corrected PET images, thus affecting both the qualitative and quantitative aspects of the dynamic PET images and the derived parametric images. In this study, we developed an automated retrospective image-based movement correction (MC) procedu...
Background: The role of fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG-PET/CT) in the surgical approach solitary pulmonary nodule (SPN) is still debated, as increased metabolic avidity lesion was not a sure sign malignancy. purpose this study to evaluate effectiveness 18F-FDG-PET/CT characterization SPN based on analysis most recent data literature.
The present study evaluates the accuracy of computed tomographic (CT) scan and positron emission tomography with (18)F-fluorodeoxyglucose (FDG-PET)/CT for the quantification of peritoneal carcinomatosis (PC) in patients undergoing cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). Data were retrospectively collected for 58 patients, who were considered for CRS an...

OBJECTIVE To compare potentials of magnetic resonance imaging (MRI), F-18 FDG, and 11C-Choline PET/CT in differentiating brain tumor recurrence from necrosis after radiotherapy. METHODS Fifty-five patients with suspected brain tumor recurrence or necrosis after radiotherapy underwent MRI, F-18 FDG, and 11C-choline PET/CT examinations, and all the patients were followed up for at least 11 mont...
In the last decades, in addition to conventional imaging techniques and magnetic resonance imaging (MRI), 18F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) has been shown to be relevant in the detection and management of breast cancer recurrence in doubtful cases in selected groups of patients. While there are no conclusive data indicating that imaging tests, ...
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...
To retrospectively investigate the diagnostic accuracy of FDG-PET/CT relative to CT for detection of cervical node metastases in patients with oral squamous cell carcinoma (OSCC), using histologic evaluation of dissected cervical nodes as the reference standard. Thirty-six patients with OSCC who underwent neck dissection (4 bilateral, 32 unilateral; 250 nodal levels) after FDG-PET/CT. Two obser...
