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

In der medizinischen Diagnostik hat die tomographische Bildgebung aufgrund des Potenzials dreidimensionaler Darstellungen eine herausragende Bedeutung erlangt. Dies vor allem seit neben den topografisch anatomischen Verfahren Computertomografie und Kernspintomografie in der funktionellen Bildgebung die Positronenemissionstomographie (PET) zusatzlich ...

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 and PET/CT in Pediatric Sarcomas
PET Clinics, 2008Because of the rarity of pediatric bone and soft tissue malignancies, it is difficult to validate the role of emerging imaging technologies in their management. The growing body of literature regarding the use of PET and PET/CT in children supports the continued investigation of this modality in the management of pediatric sarcomas.

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.

Accurate staging is essential to offer the patient the most effective available treatment and the best estimate of prognosis. In non-small cell lung cancer (NSCLC), surgical resection offers the best chance of cure in the early stages, either alone or in combination with chemo- or radiotherapy at the more advanced stages. However, many patients present

The goal of this chapter is to provide the reader with a basic understanding of Positron Emission Tomography (PET) imaging and simultaneous PET and magnetic resonance (or PET/MR) imaging. These topics are presented with particular emphasis on PET as a molecular imaging tool and MRI as a structural and functional imaging tool. The chapter begins with an

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 ...
