Background Low-dose ungated CT is commonly used for total-body PET attenuation and
scatter correction (ASC). However, CT-based ASC (CT-ASC) is limited by radiation dose …

Objective. This study presents and evaluates a robust Monte Carlo-based scatter correction
(SC) method for long axial field of view (FOV) and total-body positron emission tomography …

Objective. Lutetium yttrium oxyorthosilicate (LYSO) scintillation crystals are used in positron
emission tomography (PET) due to their high gamma attenuation, fair energy resolution, and …

Quantitative PET attenuation correction (AC) for cardiac PET/CT and PET/MR is a
challenging problem. We propose and evaluate an AC approach that uses coincidences …

On this new feature of Frontiers in Nuclear Medicine, we are delighted to present the
Research Topic Rising Stars in PET and SPECT: 2022. We would like first to thank all the …

Positron emission tomography (PET) is an important tomographic imaging modality and is
widely used in cardiology, neurology, and oncology. PET reconstruction, which is a …
