Positron emission tomography (PET) and computed tomography (CT) complement each
other's strengths in integrated PET/CT. PET is a highly sensitive modality to depict the whole …

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 …

Purpose To assess the feasibility of combined electromagnetic device tracking and
computed tomography (CT)/ultrasonography (US)/fluorine 18 fluorodeoxyglucose (FDG) …

Before the advent of tomographic imaging, it was postulated that decay of 90 Y to the 0+
excited state of 90Zr may result in emission of a positron–electron pair. While the branching …

Positron emission tomography (PET) is increasingly used for the detection, characterization,
and follow-up of tumors located in the thorax. However, patient respiratory motion presents a …

Molecular imaging plays a central role in the management of radiation oncology patients.
Specific uses of imaging, particularly to plan radiotherapy and assess its efficacy, require an …

Background PET-based texture features have been used to quantify tumor heterogeneity
due to their predictive power in treatment outcome. We investigated the sensitivity of texture …

Radiotherapy has become a critical component for the treatment of all stages and types of
lung cancer, often times being the primary gateway to a cure. However, given that radiation …

Positron emission tomography (PET) respiratory motion correction has been a subject of
great interest for the last twenty years, prompted mainly by the development of multimodality …

Purpose: Respiratory gating in PET is an approach used to minimize the negative effects of
respiratory motion on spatial resolution. It is based on an initial determination of a patient's …
