UNLABELLED Recent reports have indicated the value and limitations of (18)F-FDG PET and (201)Tl SPECT for determination of malignancy. We prospectively assessed and compared the usefulness of these scintigraphic examinations as well as (18)F-FDG PET delayed imaging for the evaluation of thoracic abnormalities. METHODS Eighty patients with thoracic nodular lesions seen on chest CT images were ...

For locally advanced cervical cancer, the current literature supports the use of (18)F-FDG PET for assessing treatment response 3 mo after the completion of concurrent chemoradiation. (18)F-FDG PET can provide reliable long-term prognostic information for these patients and, in the future, may be used to guide additional therapy. Investigational areas include the use of (18)F-FDG PET for monito...

This study aimed to stereotactically compare the PET imaging performance of (18)F-Alfatide ((18)F-ALF-NOTA-PRGD2, denoted as (18)F-Alfatide) and (18)F-fluorodeoxyglucose (FDG) and immunohistochemistry (IHC) staining in Lewis lung carcinoma (LLC) tumor-bearing C57BL/6 mouse model. (18)F-FDG standard uptake values (SUVs) were higher than (18)F-Alfatide SUVs in tumors, most of the normal tissues a...

PET with the glucose analog (18)F-FDG is increasingly used to monitor tumor response in patients undergoing chemotherapy and chemoradiotherapy. Numerous studies have shown that (18)F-FDG PET is an accurate test for differentiating residual viable tumor tissue from therapy-induced fibrosis. Furthermore, quantitative assessment of therapy-induced changes in tumor (18)F-FDG uptake may allow the pr...

The integral role of positron-emission tomography (PET) using the glucose analog tracer fluorine-18 fluorodeoxyglucose (FDG) in the staging of non-small cell lung cancer (NSCLC) is well established. Evidence is emerging for the role of PET in response assessment to neoadjuvant therapy, combined-modality therapy, and early detection of recurrence. Here, we review the current literature on these ...

UNLABELLED Accurate, early differentiation of dementias will become increasingly important as new therapies are introduced. Differential diagnosis by standard clinical criteria has limited accuracy. PET offers the potential to increase diagnostic accuracy. (18)F-FDG studies detect metabolic abnormalities in demented patients, but with limited specificity. PET also offers the ability to quantify...

UNLABELLED (18)F-FDG PET has already proved its usefulness in the follow-up of patients with alveolar echinococcosis (AE) and has been proposed as a surrogate marker for therapeutic decisions on structured treatment interruption by benzimidazoles. However, standard PET acquisition (1 h after (18)F-FDG injection) lacks sensitivity, and the parasite may stay viable even if (18)F-FDG perilesional ...

Positron emission tomography (PET) with (18)F-fluorodeoxyglucose ((18)F-FDG), a glucose analog, is widely used throughout the world as an indispensable imaging modality for the management of cancer treatment. This article reviews the pioneering achievements of PET in oncology with a focus on the development of PET that occurred from 1980 through the early-1990s. (18)F-FDG was first applied for ...

OBJECTIVES To investigate the role of whole-body fluorine-18-2-deoxy-2-fluoro-d-glucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) in the identification of peritoneal carcinomatosis in patients with ovarian cancer (OC). MATERIAL AND METHODS Seventy-nine patients with histologically proven stages III-IV OC who underwent (18)F-FDG PET/CT were studied retrospectively. We...

OBJECTIVE Follow-up of patients with oral cavity squamous cell carcinoma (OCSCC) after tumor resection and reconstruction with tissue transfer is challenging. We compared contrast-enhanced computed tomography (ceCT), (18) F-fluorodeoxyglucose-positron emission tomography combined with noncontrast enhanced CT ((18) F-FDG-PET/CT), and (18) F-FDG-PET combined with ceCT ((18) F-FDG-PET/ceCT) to det...
