PET and PET/CT in Radiotherapy
2008Many aspects have to be considered in planning, applying, and following up radiotherapy procedures. This field poses a major challenge for diagnostic techniques. The first goal in the definition of multimodal oncological therapy concepts is to identify the patients who benefit from a definitive or adjuvant radiotherapy.

Oral presentations, 2018
Objectives Concerns about unnecessary medical imaging have led to the development of guidelines for a variety of indications and modalities by radiology and specialty groups. This study evaluates the utility of four national imaging guidelines, which assess the value of positron emitting tomography/computed tomography (PET/CT).

Psychological Reports, 1998
Beneficial and adverse effects of pets for individuals in a wide range of circumstances have been reported. Nevertheless, well-designed unbiased experiments and long-term follow-up studies are needed. Pets appear to be therapeutic for some individuals and deleterious for others. The controversies concerning the effects of pets on health merit objective

From PET detectors to PET scanners
European Journal of Nuclear Medicine and Molecular Imaging, 2003This review describes the properties of available and emerging radiation detector and read-out technologies and discusses how they may affect PET scanner performance. After a general introduction, there is a section in which the physical properties of several different detector scintillators are compared.

Fundamentals of PET and PET/CT imaging
Annals of the New York Academy of Sciences, 2011In this review, the fundamental principles of fluorodeoxyglucose (FDG) positron emission tomography (PET) and FDG PET/computed tomography (CT) imaging have been described. The basic physics of PET instrumentation, radiotracer chemistry, and the artifacts, as well as normal physiological or benign pathological variants, have been described and presented

PET positive, PET negative, or PET peeve?
Blood, 2010In this issue of Blood , Horning and colleagues report that there was disagreement by 3 nuclear medicine experts on interpretation of FDG-PET images obtained in the context of a clinical trial in aggressive non-Hodgkin lymphoma 32% of the time. 1 These results emphasize the need for standardized criteria to interpret interim PET scans in lymphoma and

PET and PET/CT in Thyroid Cancer
2008Thyroid cancer can be divided into three main groups: tumors with follicle cell differentiation (differentiated thyroid cancer), tumors with C-cell differentiation (medullary thyroid cancer), and anaplastic carcinomas. The insular carcinoma takes an intermediate place between differentiated and anaplastic cancer.

PET and PET/CT in endocrine tumours
European Journal of Radiology, 2010Functional information provided by PET tracers together with the superior image quality and the better data quantification by PET technology had a changing effect on the significance of nuclear medicine in medical issues. Recently introduced hybrid PET/CT systems together with the introduction of novel PET radiopharmaceuticals have contributed to the ...
