UNLABELLED Multi-detector computed tomography (MDCT) is most commonly used for staging of non-small cell lung cancer (NSCLC). In recent years, 18F- fluorodeoxyglucose positron emission tomography combined with computed tomography (18F-FDG PET/CT) has also been used for the same purpose. Since studies comparing these two methods are scarce, our aim was to determine how the TNM classification and...

AIM To assess the relationship using multimodality imaging between intermediary citrate/choline metabolism as seen on proton magnetic resonance spectroscopic imaging (1H-MRSI) and glycolysis as observed on 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG-PET/CT) in prostate cancer (PCa) patients. METHODS The study included 22 patients with local PCa who were re...

UNLABELLED The purpose of this study was to retrospectively investigate the feasibility of 11C-choline PET, compared with 18F-FDG PET, for the detection of hepatocellular carcinoma (HCC). METHODS A total of 16 HCC lesions in 12 patients were examined with both 11C-choline PET and 18F-FDG PET. Tumor lesions were identified as areas of focally increased uptake, exceeding that of surrounding non...

We read with interest the article by Rosario et al., which summarized practical applicability of accessible imaging method in management thyroid nodules indeterminate cytologically (TNIC) (Rosario, al. 2021). For 18F-FDG-PET, it was stated that a nodule characterized low or absent 18F-FDG uptake is considered at very risk malignance, and thyroidectomy can be excluded if these tests suggest beni...

A 44-year-old female patient presented symptoms and laboratory data consistent with a Cushing’s syndrome. Endocrine investigations and negative pituitary imaging were suggestive of ectopic ACTH secretion. Therefore, the patient underwent fluorine18-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) and somatostatin receptor scintigraphy (SRS) searching for the ...

Stanford University, Department of Radiology, Division of Nuclear Medicine and Molecular Imaging, USA Here we prospectively compared the combined 18F NaF/18F FDG PET/ MRI against 99mTc-MDP in patients with breast and prostate cancers. Twelve patients referred for 99mTc-MDP bone scans were prospectively enrolled from Oct 14 Jan 15. The cohort included 6 men with prostate cancer and 6 women with ...

Early diagnosis of infective endocarditis (IE) is based on the yielding of blood cultures and echocardiographic findings. However, they have limitations and sometimes the diagnosis is inconclusive, particularly in patients with prosthetic valves (PVs) and implantable cardiac electronic devices (ICEDs). The primary aim of this study was to evaluate the diagnostic accuracy of 18F-FDG PET/CT in pa...

BACKGROUND This study investigated the relationships between background intestinal uptake on 18F-FDG PET and cardio-metabolic risk (CMR) factors. METHODS A total of 326 female patients that underwent 18F-FDG PET to determine the initial stage of breast cancer were enrolled. None of the patients had history of diabetes or hypertension. The background intestinal uptake on PET was visually grade...

BACKGROUND Atherosclerosis is a progressive inflammatory condition that underlies coronary artery disease (CAD)-the leading cause of death in the United States. Thus, the ultimate goal of this research is to advance our understanding of human CAD by improving the characterization of metabolically active vulnerable plaques within the coronary arteries using a novel catheter-based imaging system....

Hellenic Journal of Nuclear Medicine January April 2011 www.nuclmed.gr 2 Figures 2 and 3. 131I-SPET study (Fig. 2) further clarified these foci in both kidneys. 18F-FDG-PET scan (Fig. 3) done on a separate day revealed abnormal foci of 18F-FDG uptake in the lower poles of both kidneys, corresponding to the foci seen on post treatment 131I-SPET. In the 18F-FDG-PET image, the foci can be well vis...
