MRI examination includes coronal, sagittal T1, T1 post-contrast, and dynamic contrast sequences. Dynamic contrast-enhanced images crucial for detecting small microadenomas
Hypothalamus-pituitary complex serves as endocrine system's command center. Hypothalamus lies anterior to thalamus, connected to pituitary by infundibulum. Pituitary gland consists of posterior (neurohypophysis) and anterior (adenohypophysis) lobes
Connects hypothalamus with anterior pituitary through blood vessels. Contains fenestrated capillaries for rapid hormone exchange. Transports hormones like GnRH, CRH, GHRH, and TRH. Blood supply comes from superior hypophyseal arterial system
Anterior pituitary is glandular lobe of pituitary gland located at brain base. Composed of pars distalis, pars tuberalis, and pars intermedia regions. Derived from ectoderm, specifically Rathke's pouch in embryo. Contains five types of endocrine cells secreting various hormones
Sella turcica is a saddle-shaped depression in sphenoid bone. Located in middle cranial fossa behind chiasmatic groove. Contains pituitary gland in hypophyseal fossa. Forms bony seat for pituitary gland. Completed posteriorly by dorsum sellae and clivus
