Description of the subject Molecular imaging, in particular positron emission tomography (β+) imaging (PET), has become essential for the diagnosis of many diseases such as cancers. The rise of this non-invasive technique is linked to the obtaining of three-dimensional images, after radiotracer injection, allowing the localization and quantification of pathology-specific targets. Radiotracers are also used for the cancer treatment by targeted radionuclide radiotherapy (TRT). These radiotracers mainly combine a targeting agent, interacting with a pathology biomarker, and a radionuclide chelating … Continue reading
