UNLABELLED We aimed to evaluate (68)Ga-DOTATATE PET/CT for the early prediction of time to progression and clinical outcome after a first cycle of peptide receptor radionuclide treatment (PRRT) in a cohort of patients with well-differentiated neuroendocrine tumors. METHODS Thirty-three consecutive patients (22 men and 11 women; mean age +/- SD, 57.8 +/- 12.1 y) were investigated at baseline a...

BACKGROUND The standardized uptake value (SUV) is the nearly exclusive means for quantitative evaluation of clinical [18F-]fluorodeoxyglucose (18F-FDG) positron emission tomography (PET) whole body investigations. However, the SUV methodology has well-known shortcomings. In this context, it has been recognized that at least part of the problems can be eliminated if tumor SUV is normalized to th...

It is well known that many technical and physiologic factors can affect the reliability of the standardized uptake value (SUV) on FDG PET-CT. Another potential problem of which we may be aware but has not been previously discussed is significant SUV overestimation of lesions in the direct neighborhood of large hot sources, namely, areas with high FDG uptake or activity such as a tumor, myocardi...

UNLABELLED Tumor delineation using noninvasive medical imaging modalities is important to determine the target volume in radiation treatment planning and to evaluate treatment response. It is expected that combined use of CT and functional information from 18F-FDG PET will improve tumor delineation. However, until now, tumor delineation using PET has been based on static images of 18F-FDG stand...

Currently, positron emission tomography with computerized tomography (PET-CT) is the most sensitive technique for detecting extracranial metastases in non-small cell lung cancer (NSCLC). It has been reported that there is a correlation between the maximal standardized uptake value (SUV(max)) of primary tumors and prognosis in patients with NSCLC. The effect of sunlight exposure on PET-CT SUV(ma...

OBJECTIVES Expression of HER2 in gastric carcinoma has direct prognostic and therapeutic implications in patient management. The aim of this study is to determine whether a relationship exists between standardized uptake value (SUV) and expression of HER2 in advanced gastric carcinoma. METHODS We analyzed the (18)F-FDG PET/CT results of 109 patients that underwent gastrectomy for advanced gas...

PURPOSE 11C-Acetate is radiotracer being considered an alternative to 18F-fluorodeoxyglucose. Evaluation of 11C-acetate biodistribution in human parenchymal organs is described. METHODS AND MATERIALS 60 consecutive patients referred to 11C-acetate PET CT suspected of renal or prostate cancer relapse with negative results (no recurrent tumor) were included in the study. Acquisition from the ba...

OBJECTIVE The aim of this report is to describe the potential clinical utility of tracer [F-18]-Fluorodeoxyglucose (FDG) uptake, quantitated as a standardized uptake value (SUV) by positron emission tomography (PET), to evaluate treatment response to neoadjuvant chemotherapy (NAC) in advanced uterine cervical cancer. METHODS We briefly describe the clinical courses of three women with advance...

AIM To analyse the correlation between (18)F-FDG uptake assessed by PET/CT in locally advanced breast tumours and histopathological and immunohistochemical prognostic factors. MATERIAL AND METHODS Thirty-six women with breast cancer were prospectively evaluated. PET/CT was requested in the initial staging previous to adjuvant chemotherapy (multicentric study). All the patients underwent an (1...

BACKGROUND The purpose of this study was to determine whether the pretreatment primary tumor standardized uptake value (SUV), as measured by positron emission tomography (PET), can add prognostic information for predicting survival in patients with head and neck squamous cell carcinoma (HNSCC). MATERIALS AND METHODS 7 articles were identified by searching electronic databases. Statistical ana...
