Time-of-flight (TOF) PET/MR imaging is an emerging imaging technology with great
capabilities offered by TOF to improve image quality and lesion detectability. We assessed …

Quantitative PET imaging relies on accurate attenuation correction. Recently, there has
been growing interest in combining state-of-the-art PET systems with MR imaging in a …

The joint maximum-likelihood reconstruction of activity and attenuation (MLAA) for emission-
based attenuation correction has regained attention since the advent of time-of-flight …

Purpose The objective of this study was to evaluate the performance of the built-in MR-
based attenuation correction (MRAC) included in the combined whole-body Ingenuity TF …

Purpose We compare the performance of three commonly used MRI‐guided attenuation
correction approaches in torso PET/MRI, namely segmentation‐, atlas‐, and deep learning …

Abstract Objective Hybrid PET/MRI presents many advantages in comparison with its
counterpart PET/CT in terms of improved soft-tissue contrast, decrease in radiation …
