Frequency and intensity of [18F]-PSMA-1007 uptake after COVID-19 vaccination in clinical PET [PDF]
, 2022 Objectives: To assess the frequency and intensity of [18F]-prostate-specific membrane antigen (PSMA)-1007 axillary uptake in lymph nodes ipsilateral to COVID-19 vaccination with BNT162b2 (Pfizer-BioNTech) or mRNA-1273 (Moderna) in patients with prostate ...

Correction of scan time dependence of standard uptake values in oncological PET [PDF]
EJNMMI Research, 2014 Standard uptake values (SUV) as well as tumor-to-blood standard uptake ratios (SUR) measured with [ 18F-]fluorodeoxyglucose (FDG) PET are time dependent. This poses a serious problem for reliable quantification since variability of scan start time relative to the time of injection is a persistent issue in clinical oncological Positron emission ...

Imaging Hepatocellular Carcinoma With 68Ga-Citrate PET: First Clinical Experience. [PDF]
, 2017 While cross-sectional imaging with computed tomography (CT) and magnetic resonance imaging is the primary method for diagnosing hepatocellular carcinoma (HCC), they provide little biological insight into this molecularly heterogeneous disease.

Biases in Multicenter Longitudinal PET Standardized Uptake Value Measurements
Translational Oncology, 2014 This study investigates measurement biases in longitudinal positron-emission tomography/computed tomography (PET/CT) studies that are due to instrumentation variability including human error. Improved estimation of variability between patient scans is of particular importance for assessing response to therapy and multicenter trials.

Comparison of standardized uptake values with volume of distribution for quantitation of [11C]PBR28 brain uptake [PDF]
Nuclear Medicine and Biology, 2015 [(11)C]PBR28 is a high-affinity ligand for the Translocator Protein 18 kDa (TSPO), which is considered to be a marker for microglial activation. Volume of distribution (VT) estimated with an arterial plasma input function is the gold standard for quantitation of [(11)C]PBR28 binding.

Repeatability of the Maximum Standard Uptake Value (SUVmax) in FDG PET
Malecular Imaging and Radionuclide Therapy, 2014 SUVmax is often calculated at FDG PET examinations in systematic studies as well as at clinical examinations. Since SUVmax represents a very small portion of a lesion it may be questioned how statistically reliable the figure is. This was studied by assessing the repeatability of SUVmax between two FDG acquisitions acquired immediately upon each other ...

Significance of FDG–PET standardized uptake values in predicting thyroid disease
European Thyroid Journal, 2023 Objective This study aimed to determine a standardized cut-off value for abnormal 18F-fluorodeoxyglucose (FDG) accumulation in the thyroid gland. Methods Herein, 7013 FDG–PET/CT scans were included. An automatic thyroid segmentation method using two U-nets (2D- and 3D-U-net) was constructed; mean FDG standardized uptake value (SUV), CT value, and ...

Associations Between Atrial Cardiopathy and Cerebral Amyloid: The ARIC‐PET Study
Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020 Background Atrial fibrillation (AF) is a risk factor for cognitive decline, possibly from silent brain infarction. Left atrial changes in structure or function (atrial cardiopathy) can lead to AF but may impact cognition independently.

U-Net-based SUV calculation in FDG-PET imaging of mice brain for enhanced analysis
Current Directions in Biomedical Engineering, 2023 Positron emission tomography (PET) is a widely used imaging modality in nuclear medicine for a variety of applications. Amongst the methods used for the quantifying and interpretation of PET images, the standardized uptake value (SUV) is a widely-adopted
