Illustrations pratiques – Produits de contraste iodés (PCI)

Iodinated Contrast Agent (ICA) may be used in nuclear medicine for level 3 and 4 CT level. The use of ICA in SPECT/CT or PET/CT is driven, for each patient, by the clinical context, the benefit/risk ratio and the availability and the date of the previous injected CT. The improvement in diagnostic performance of the exam is the main goal of the ICA injection during a hybrid NM procedure.     

Guide du bon usage de la TDM en médecine nucléaire. IntroductionCT good practices for hybrid nuclear medicine (SPECT/CT and PET/CT): Introduction

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.

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.     

Rappels physiques et outils d’optimisation de la qualité image et de la dose

Many parameters can affect the patient's dose and the CT image quality. It is therefore essential, in order to optimize the patient's dosimetry, to know the influence of these parameters as well as their link with the dose modulation tools.
