PURPOSE The present study aimed to determine whether fractal analysis of morphological complexity and intratumoral heterogeneity of FDG uptake can help to differentiate malignant from benign pulmonary nodules. MATERIALS AND METHODS We retrospectively analyzed data from 54 patients with suspected non-small cell lung cancer (NSCLC) who were examined by FDG PET/CT. Pathological assessments of bi...
UNLABELLED Molecular imaging of the 18 kD Translocator protein (TSPO) with positron emission tomography (PET) is of great value for studying neuroinflammation in rodents longitudinally. Quantification of the TSPO in rodents is, however, quite challenging. There is no suitable reference region and the use of plasma-derived input is not an option for longitudinal studies. The aim of this study wa...
OBJECTIVE Relation between patient age and Hounsfield Unit (HU),which is the linear attenuation coefficient, and Standardized Uptake Values (SUV) which is the amount of 18F-fluorodeoxyglucose (F-18 FDG) uptake, measured in the areas of interest drawn to prostate, seminal vesicles and testicles in F-18 FDG Positron Emission Tomography/Computed Tomography (PET/CT) images was investigated. MATER...
Oligodendroglial components (OC) and loss of heterozygosity on chromosomes 1p and 19q (LOH 1p/19q) are associated with better outcome in patients with glioma. We aimed to assess the fitness of [(18)F]fluoroethyltyrosine positron-emission-tomography (FET-PET) for noninvasively identifying these important prognostic/predictive factors. One hundred forty-four patients with MRI-suspected WHO grade ...
PURPOSE In patients with head and neck cancer enrolled onto a prospective study of positron emission tomography (PET), pretreatment 2-[(18)F] fluoro-2- deoxy-D-glucose (FDG) uptake was evaluated as a predictor of local control and disease-free survival (DFS) after treatment by radiotherapy (RT) with or without chemotherapy. PATIENTS AND METHODS We studied 63 patients with carcinomas of the he...
AIM The aim of this paper is to describe the imaging pattern of focal nodular hyperplasia (FNH) by l8F-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET). METHODS Eight consecutive asymptomatic patients with histologic proof of FNH underwent 18F-FDG PET imaging. The lesions were found incidentally. The 18F-FDG PET imaging was performed with a dedicated PET tomograph after intrave...
Objectives: The aim of this prospective study was to assess the influence of different normalisation procedures on relative changes in standardised uptake values (SUV) of FDGPET for the assessment of chemotherapy response in patients with colorectal carcinoma (CRC) and non-small cell lung carcinoma (NSCLC). Methods: In 97 patients with CRC 5 (n=48) and NSCLC (n=49) FDG-PET was performed before ...
BACKGROUND The current study focuses on the prognostic value of pretreatment metabolic activity in metastases as measured with [(18)F]fluorodeoxyglucose positron emission tomography (FDG-PET), as an indicator of survival in colorectal cancer. PATIENTS AND METHODS In a prospective series of 152 patients with metastatic colorectal cancer, of whom 67 were treated with resection of metastases and...
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...
In this study, microemulsions of the chiral surfactant polysodium N-undecenoyl-D-valinate (poly-D-SUV) was utilized for enantiomeric separation by investigating two approaches using polymeric chiral surfactant in microemulsion electrokinetic chromatography (MEEKC). In the first approach, poly-D-SUV was used as an emulsifier surfactant along with 1-butanol and n-heptane. Enantioseparation of ani...
