The problem of attenuation correction (AC) for quantitative positron emission tomography
(PET) had been considered solved to a large extent after the commercial availability of …

1469 Objectives: The success of whole-body (WB) PET/CT has led to an increased interest
also in combined PET/MR as a complementary hardware combination. However, neither …

After more than 20 years of research, a fully integrated PET/MR scanner was launched in
2010 enabling simultaneous acquisition of PET and MR imaging. Currently, no clinical …

Background Positron emission tomography (PET)/magnetic resonance (MR) imaging may
become increasingly important for assessing tumor therapy response. A prerequisite for …

PET and MRI provide complementary data that are routinely analyzed concurrently in
research and clinical applications. Recognizing the potential to combine the strengths of the …

2057 Background: Quiescent period gating (QPG) of positron emission tomography (PET)
studies has been shown to reduce motion artifacts. In addition, QPG of the attenuation …

Attenuation correction (AC) is a critical step in the reconstruction of quantitatively accurate
positron emission tomography (PET) and single photon emission computed tomography …

Purpose We compare the quantitative accuracy of magnetic resonance imaging (MRI)-
based attenuation correction (AC) using the 3-class attenuation map (PET-MRAC3c) …

Combined PET/MR systems for whole body investigations have been developed recently
and are now starting to become available. One of the first of these systems (Gemini TF …

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 …
