Positron emission tomography (PET) is an imaging modality to better understand the pathophysiology of a disease at molecular level and typically referred to as molecular imaging. It reveals the variability in a biochemical process of organs and tissues under pathological condition with respect to the normal condition. A radioactive tracer is injected into the patient to show areas in the body with an increased uptake, which is often indicative of a pathological condition. PET imaging can be more sensitive compared to other imaging modalities, like Magnetic Resonance Imaging.
This Collection seeks submissions from researchers and clinicians applying PET imaging with novel biological targets, novel radiotracers, and the evaluation of these techniques in preclinical and clinical studies to better understand the disease pathology.
