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

Attenuation correction has been one of the main methodological challenges in the
integrated positron emission tomography and magnetic resonance imaging (PET/MRI) field …

Aim To accurately quantify the radioactivity concentration measured by PET, emission data
need to be corrected for photon attenuation; however, the MRI signal cannot easily be …

Accurate attenuation correction (AC) on PET/MR is still challenging. The purpose of this
study was to evaluate the clinical feasibility of AC based on fast zero-echo-time (ZTE) MRI by …

Purpose To determine the level of clinically acceptable reduction in injected fluorine 18
(18F) fluorodeoxyglucose (FDG) dose in time-of-flight (TOF)–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 …

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 …

In brain PET/MR applications, accurate attenuation maps are required for accurate PET
image quantification. An implemented attenuation correction (AC) method for brain imaging …

Background To compare the diagnostic accuracy of PET/MR and PET/CT in patients with
suspected occult primary tumors. Methods This prospective study was approved by the …

Purpose Neuropathological studies have demonstrated distinct profiles of microglia
activation and myelin injury among different multiple sclerosis (MS) phenotypes and …
