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 …

Positron emission tomography (PET) is a molecular imaging technique which provides
important functional information about the human body. However, thoracic PET images are …

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 …

Combined PET/computed tomography (CT) is of value in cancer diagnosis, follow-up, and
treatment planning. For cancers located in the thorax or abdomen, the patient's breathing …

The problem of motion is well known in positron emission tomography (PET) studies. The
PET images are formed over an elongated period of time. As the patients cannot hold breath …

The effect of physiological motion in emission tomography is a reduction in overall image
contrast and loss of sensitivity. In particular, respiratory motion affects imaging in the thoracic …

Positron emission tomography (PET) has shown an increase in both sensitivity and
specificity over computed tomography (CT) in lung cancer. However, motion artifacts in the …

This study proposes a new method to reduce respiratory motion artifacts in PET images of
lung cancer. The method is referred to as respiratory-correlated dynamic PET (RCDPET) …

PURPOSE: To describe the degradation effects produced by respiratory organ and lesion
motion on PET/CT images and to define the role of respiratory gated (RG) 4D-PET/CT …

Respiratory motion in PET and PET/CT blurs the images and can cause attenuation‐related
errors in quantitative parameters such as standard uptake values. In rare instances, this …
