The signaling molecule histamine plays a key role in the mediation of immune reactions, in gastric secretion, and in the sensory system. In addition, it has an important function as a neurotransmitter in the central nervous system, acting in pituitary hormone secretion, wakefulness, motor and cognitive functions, as well as in itch and nociception. This has raised interest in the role of the histaminergic system for the treatment and diagnosis of various pathologies such as allergy, sleeping and eating disorders, neurodegeneration, neuroinflammation, mood disorders, and pruritus. In the past 20 years, several ligands targeting the four different histamine receptor subtypes have been explored as potential radiotracers for positron emission tomography. This contribution provides an overview of the developments of subtype-selective carbon-11-labeled and fluorine-18-labeled compounds for imaging in the brain. Using specific radioligands, we could examine the H
