Results We compared the SUVmax between good (Japan Esophageal Society response evaluation criteria grades 3/2; n = 87, 78.4 %) and poor (grade 1; n = 24, 21.6 %) responders. The SUVmax after nCRT (post-SUVmax) in good and poor responders were 2.7 ± 0.9 and 4.4 ± 2.2, respectively (p < 0.0001). The rates of the SUVmax decrease after nCRT (ΔSUVmax) in these patients significantly differed (71 ± 1...

The aim of this study was to investigate the relationship between standardized uptake value (SUV), obtained from [18F]fluorodeoxyglucose positron emission tomography (FDG PET), and treatment response and survival of inoperable NSCLC patients treated with high dose radiotherapy. Fifty-one patients were included, recording stage, performance, weight loss, tumour volume, histology, lymph node invo...

BACKGROUND The primary aim of this study was to examine if factors such as renal function, height, weight and age could affect the uptake of sodium fluoride-18 (NaF-18) by the normal bone. This is the first study to examine the possible factors that can influence NaF-18 uptake in the normal bone. METHODS A retrospective study was done on NaF-18 PET/CT bone scans from January 2010 to May 2012 ...

The aim of this study was to analyze the relationship between the maximum standardized uptake value (SUVmax) of 18F-fluoro-2-deoxyglucose-positron emission tomography (FDG-PET) and the effects of neoadjuvant chemoradiotherapy in oral squamous cell carcinoma (OSCC), and to identify the possible biological background of this association. Thirty-seven patients with OSCC, who underwent preoperative...

Pulmonary carcinoids are histologically classified into typical and atypical. It is important to identify these preoperatively for treatment planning and prognosis. Structural imaging cannot conclusively differentiate between them. The aim of this study was to assess the possibility of differentiating the 2 variants using [18F]fluorodeoxyglucose (FDG)-positron emission tomography (PET)/computed...

OBJECTIVE In this study, we aimed to determine the correlation between pretreatment-staging 18F-FDG total body positron-emission tomography/computed tomography (PET/CT) maximum standardized uptake value (SUVmax) levels and histopathologic and immunohistochemical predictive and prognostic factors in patients with breast cancer. MATERIALS AND METHODS One hundred thirty-nine women with breast ca...

BACKGROUND AND OBJECTIVES We retrospectively evaluated the value of PET/CT in predicting survival and histopathological tumour-response in patients with distal oesophageal and gastric adenocarcinoma following neoadjuvant treatment. METHODS Twenty-one patients with resectable distal oesophageal adenocarcinoma and 14 with gastric adenocarcinoma between January 2002 and December 2011, who had un...

CONTEXT Localization of the primary tumor and detection of metastases are essential for preoperative planning and postoperative management of pheochromocytoma. When computed tomography (CT) and magnetic resonance imaging are inadequate, functional imaging adds important information in this respect. OBJECTIVE In this study the efficacy of positron emission tomography (PET) and PET/CT with (11)...

OBJECTIVES (18)F-fluoro-2-deoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) is extensively used to diagnose and stage of lung cancer. The aim of the current study was to investigate the correlation of demographic, clinical, pathological and radiological factors with primer tumor FDG Uptake in patients with lung cancer. MATERIALS AND METHODS This cross-sectional, c...

BACKGROUND We evaluated the prognostic significance of standardized uptake value (SUVmax), metabolic tumour volume (MTV), and total lesion glycolysis (TLG) in [F-18] FDG PET/CT findings in patients with inoperable non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS One hundred and three patients (mean age, 65.6 ± 16 years) underwent [F-18] FDG PET/CT before the chemotherapy. The SUVmax v...
