Comparing Diagnostic Performance of Short and Long [¹⁸F]FDG-PET Acquisition Times in Giant Cell Arteritis

Diagnostics, 2023
(1) Background: In giant cell arteritis (GCA), the assessment of cranial arteries using [18F]fluorodeoxyglucose ([18F]FDG) positron emission tomography (PET) combined with low-dose computed tomography (CT) may be challenging due to low image quality ...

Feasibility of Systematic Respiratory-Gated Acquisition in Unselected Patients Referred for 18F-Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography

Frontiers in Medicine, 2018
ObjectiveRespiratory motion in 18F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) induces blurred images, leading to errors in location and quantification for lung and abdominal lesions.

Diagnostic role and prognostic impact of positron emission tomography/computed tomography in patients treated for uterine corpus cancer [PDF]

Srpski Arhiv za Celokupno Lekarstvo
Introduction/Objective. The goal of our research was to evaluate diagnostic and prognostic role of positron emission tomography/computed tomography (PET-CT) in patients previously treated for uterine cancer and compare it to conventional imaging methods (

Effects of Fluorodeoxyglucose Conjugated and Unconjugated Iron Oxide Magnetic Nanoparticles on Macrophages: a Pilot Study

Brazilian Archives of Biology and Technology, 2021
The effects of fluorodeoxyglucose conjugated iron oxide magnetic nanoparticles (FDGMNP) on macrophages are presented using a yeast substrate. Iron oxide magnetic nanoparticles (MNP) were synthesized by partially reducing FeCl3, then conjugated with (3 ...

Does Routine Triple-Time-Point FDG PET/CT Imaging Improve the Detection of Liver Metastases?

Diagnostics, 2020
Prior reports have demonstrated the improved ability of delayed fluorine-18 (18F) fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) imaging (dual-time-point imaging) in detecting more patients with liver metastases.

Clustering Analysis of FDG-PET Imaging in Primary Progressive Aphasia

Frontiers in Aging Neuroscience, 2018
Background: Primary progressive aphasia (PPA) is a clinical syndrome characterized by the neurodegeneration of language brain systems. Three main clinical forms (non-fluent, semantic, and logopenic PPA) have been recognized, but applicability of the ...

AutoPET Challenge 2023: Sliding Window-based Optimization of U-Net [PDF]

arXiv, 2023
Tumor segmentation in medical imaging is crucial and relies on precise delineation. Fluorodeoxyglucose Positron-Emission Tomography (FDG-PET) is widely used in clinical practice to detect metabolically active tumors. However, FDG-PET scans may misinterpret irregular glucose consumption in healthy or benign tissues as cancer. Combining PET with Computed

Construction of an individualized brain metabolic network in patients with advanced non-small cell lung cancer by the Kullback-Leibler divergence-based similarity method: A study based on 18F-fluorodeoxyglucose positron emission tomography

Frontiers in Oncology, 2023
BackgroundLung cancer has one of the highest mortality rates of all cancers, and non-small cell lung cancer (NSCLC) accounts for the vast majority (about 85%) of lung cancers.

Boost-S: Gradient Boosted Trees for Spatial Data and Its Application to FDG-PET Imaging Data [PDF]

arXiv, 2021
Boosting Trees are one of the most successful statistical learning approaches that involve sequentially growing an ensemble of simple regression trees (i.e., "weak learners"). However, gradient boosted trees are not yet available for spatially correlated data.
