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

Multiparametric Cardiac 18F-FDG PET: Pilot Comparison of FDG Delivery Rate with 82Rb Myocardial Blood Flow [PDF]
Myocardial blood flow (MBF) and flow reserve are usually quantified in the clinic with positron emission tomography (PET) using a perfusion-specific radiotracer (e.g. 82Rbchloride). However, the clinical accessibility of existing perfusion tracers remains limited.

Carbohydrate antigen 19–9 (CA 19–9), also known as sialyl Lewis A, is a tetrasaccharide overexpressed on a wide range of cancerous cells, most prominently pancreatic ductal adenocarcinoma. The review discusses the synthesis of CA 19–9, elicitation of antibodies through vaccination, development of anti‐CA 19–9 monoclonal antibodies, and their ...

A resource-efficient deep learning framework for low-dose brain PET image reconstruction and analysis [PDF]
18F-fluorodeoxyglucose (18F-FDG) Positron Emission Tomography (PET) imaging usually needs a full-dose radioactive tracer to obtain satisfactory diagnostic results, which raises concerns about the potential health risks of radiation exposure, especially for pediatric patients.

The status of MRI databases across the world focused on psychiatric and neurological disorders
Neuroimaging databases for neuro‐psychiatric disorders enable researchers to implement data‐driven research approaches by providing access to rich data that can be used to study disease, build and validate machine learning models, and even redefine disease spectra.

Gamma--ray emission from individual classical novae [PDF]
Classical novae are important producers of radioactive nuclei, such as be7, n13, f18, na22 and al26. The disintegration of these nuclei produces positrons (except for be7) that through annihilation with electrons produce photons of energies 511 keV and below.

Self-Supervised Learning for Physiologically-Based Pharmacokinetic Modeling in Dynamic PET [PDF]
Dynamic positron emission tomography imaging (dPET) provides temporally resolved images of a tracer enabling a quantitative measure of physiological processes. Voxel-wise physiologically-based pharmacokinetic (PBPK) modeling of the time activity curves (TAC) can provide relevant diagnostic information for clinical workflow.
