PURPOSE To evaluate the role of (18)F-flurodeoxiglucose positron emission tomography/computed tomography ((18)F-FDG-PET/CT) in predicting malignancy of thyroid nodules with indeterminate cytology. PATIENTS AND METHODS We analysed 87 patients who have been scheduled to undergo surgery for thyroid nodule with indeterminate cytology. All patients underwent (18)F-FDG-PET/CT, multiparametric neck ...

To evaluate (18)F-labeled-fluorodeoxyglucose ((18)F-FDG-) and (18)F-labeled-sodium fluoride ((18)F-NaF-) positron emission tomography/computed tomography (PET/CT) as biomarkers in metastatic castrate-resistant prostate cancer (mCRPC). Nine men (53-75 years) in a phase 1 trial of abiraterone and cabozantinib had (18)F-FDG-PET/CT, (18)F-NaF-PET/CT and standard imaging ((99m)Tc-labeled-methylene-d...

Fluorine-18-fluorodeoxyglucose ((18)F-FDG ) positron emission tomography/computed tomography (PET/CT) with the in-hospital synthesis of (18)F-FDG was initiated in our hospital on April 1, 2010. We aim to perform stable supply of (18)F-FDG for patients and to avoid unnecessary radiation exposure due to mis-preparation of (18)F-FDG. Pharmacists perform quality control tests to determine whether (...

UNLABELLED In this pilot study, we evaluated 3'-deoxy-3'-(18)F-fluorothymidine (FLT) PET for the detection of gastric cancer and compared the diagnostic accuracy with that of (18)F-FDG PET. METHODS Forty-five patients (31 male and 14 female) with histologically proven locally advanced gastric cancer underwent attenuation-corrected whole-body (18)F-FLT PET and (18)F-FDG PET/CT (low-dose CT). (...

PURPOSE The aim of this study was to evaluate the effect of combined (68)Ga and (18)F-FDG PET/CT on treatment management for patients with pancreatic neuroendocrine tumor (PNET). METHODS Between January 2012 and April 2014, 49 consecutive patients with a cytologically and/or histologically proven diagnosis of PNET underwent combined (68)Ga and (18)FDG PET/CT on the same day. RESULTS The stu...

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 ...

Background: A 2-deoxy-2-[18F]fluoro-D-glucose (FDG) is useful for early metabolic response assessment in various malignancies, including Colorectal Cancer (CRC). Herein, we express that Positron Emission Tomography/Computed (PET-CT) with FDG was very useful for early diagnosis, accuracy and additional value of whole-body in recurrent CRC. Case Report: A 50 years old woman was diagnosed with an ...

OBJECTIVES Although diffuse splenic (18)F-fluorodeoxyglucose (F-18 FDG) uptake exceeding hepatic activity, is considered abnormal, its clinical significance is rarely discussed in the literature. The aim of this study was to determine the contributing factors causing diffusely increased splenic FDG uptake in patients with cholangiocarcinoma. METHODS From January 2010 to March 2013, 140 patien...

BACKGROUND Pheochromocytomas and paragangliomas (PPGLs) are rare tumors of the adrenal medulla and extra-adrenal sympathetic chromaffin tissues; their anatomical and functional imaging are critical to guiding treatment decisions. This study aimed to compare the sensitivity and specificity of (18)F-fluorodeoxyglucose positron emission tomography with computed tomography ((18)F-FDG PET/CT) for tu...
