Purpose Respiratory motion of lung lesions is a limiting factor of quantification of positron
emission tomography (PET) data. As some important applications of PET such as therapy …

Hybrid PET/MR combines the exceptional molecular sensitivity of PET with the high
resolution and versatility of MR imaging. Simultaneous data acquisition additionally …

PET-CT scanners allow robust and synergistic fusion of anatomic and functional information,
which has improved sensitivity, specificity, and enhancement in the value of PET and CT …

Purpose: Despite multiple methodologies already proposed to correct respiratory motion in
the whole PET imaging field of view (FOV), such approaches have not found wide …

Motion is a source of degradation in positron emission tomography (PET)/computed
tomography (CT) images. As the PET images represent the sum of information over the …

Respiratory motion during the CT and PET parts of a PET/CT scan leads to imperfect
alignment of anatomic features seen by the 2 modalities. In this work, we concentrate on the …

Background and Objective: Breathing movement can introduce heavy bias in both image
quality and quantitation in PET/CT. The aim of this paper is a review of the literature to …

One of the main degrading factors in the quality of oncologic PET images of the thorax and
upper abdomen is respiratory motion of tumors. One method to reduce this effect is the …

Detectability of lung tumors in PET images is severely compromised by respiratory motion. In
this work we investigate the performance of three different motion correction schemes for the …

The impact of a method for MR-based respiratory motion correction of PET data on lesion
visibility and quantification in patients with oncologic findings in the lung was evaluated …
