Hybrid Imaging in Non-thyroidal Endocrinological Disorders
Adrenal glands are two organs of the endocrine system that secrete different types of hormones. They are located in the retroperitoneal space, surrounded by a thick fibrous capsule, placed immediately below the diaphragm, superiorly and medially to the kidneys, between the 12th thoracic and the 1st lumbar vertebra. They have a cone shape with an inferior base, a weight of about 8 g, and sizes of about 2–3 cm in width and 4–6 cm in length. They are richly vascularized, innervated by the autonomous system, mainly through the adrenal plexus. Each adrenal consists of two distinct parts: a peripheral part, called adrenal cortex, and a central part, called adrenal medulla.
