Attenuation correction (AC) is essential for the generation of artifact-free and quantitatively
accurate positron emission tomography (PET) images. PET AC based on computed …

Since the seventies, positron emission tomography (PET) has become an invaluable
medical molecular imaging modality with an unprecedented sensitivity at the picomolar …

When this article was written, it coincided with the 11th anniversary of the installation of our
PET/MR device in Munich. In fact, this was the first fully integrated device to be in clinical …

Purpose To provide practice guideline/procedure standards for diagnostics and therapy
(theranostics) of meningiomas using radiolabeled somatostatin receptor (SSTR) ligands …

The first time-of-flight positron emission tomography (TOF-PET) scanners were developed
as early as in the 1980s. However, the poor light output and low detection efficiency of TOF …

Attenuation correction (AC) is essential for quantitative analysis and clinical diagnosis of
single-photon emission computed tomography (SPECT) and positron emission tomography …

Preclinical and postmortem studies have suggested that regional synaptic density and
glucose consumption (CMRGlc) are strongly related. However, the relation between …

In this review, we will summarize the past and current state-of-the-art developments in
attenuation and scatter correction approaches for hybrid positron emission tomography …

Accurate MR-based attenuation correction (MRAC) is essential for quantitative PET/MR
imaging of the brain. In this study, we analyze the regional bias caused by MRAC based on …

Purpose This study aims to compare two approaches using only emission PET data and a
convolution neural network (CNN) to correct the attenuation (μ) of the annihilation photons in …
