The examples and clinical cases presented in this section are not intended to be considered as absolute models in terms of image quality or device parameter settings. They must initiate an individual analysis according to CT parameters and image quality. Nevertheless, they present practically different CT levels, which can be used according to the clinical context and the type of device. (C) 2018 Elsevier Masson SAS. All rights reserved.

Once the imaging examination is justified by the clinical context, given the low doses of ionizing radiation delivered by nuclear imaging, the quality of the medical diagnosis always takes precedence over dosimetric considerations. Corollary to this assertion, the voluntary alteration of the image quality and therefore of the quality of the diagnosis on the basis of radiation protection considerations alone constitutes medical malpractice.

Les exemples et les cas cliniques présentés dans cette partie n’ont pas vocation à être considérés comme des modèles absolus en termes de qualité image ou de paramétrage des appareils. Les exemples doivent contribuer à initier une réflexion individuelle concernant le paramétrage du scanner en fonction de la situation clinique, du niveau de scanner que l’on souhaite réaliser et de l’appareillage dont on dispose. Ils permettent de présenter de manière concrète à partir d’images de sélection, des exemples des différents niveaux de scanner envisageables dans une situation donnée.

Nuclear medicine hybrid imaging is a technological evolution of gamma camera scintigraphy or positron emission tomography imaging methods that are now often coupled with an anatomical imaging device, essentially a CT scanner. Following a large demand from the nuclear physicians themselves, but also from the French Nuclear Safety Authority, this guide is intended for the entire nuclear medicine community to integrate both the aspects of radiation protection related to coupled CT and those related to the quality of the CT images according to the clinical context.
