"The posterior pituitary bright spot, having intrinsically high signal on T1 weighted images is believed to be from the storage of vasopressin (antidiuretic hormone or ADH), which has a T1-shortening effect 2. The hormone is synthesised in the hypothalamus and carried down the axons that form the stalk to the posterior pituitary bound to a vasopressin-neurophysin II-copeptin complex, a macromolecular structure that shortens T1 relaxation time 4."
