Abstract:
The pituitary gland is housed in the sella turcica and has vital endocrinologic functions. It lies in close proximity to numerous vital structures, including the optic chiasm, sphenoid sinus, cavernous sinus and hypothalamus. An understanding of the function, anatomy and embryology of the pituitary gland and its surrounding structures is vital to understanding its normal appearance, as well as in evaluating the broad spectrum of pathology that can involve the pituitary gland. Imaging of pathology in the sellar region, including pituitary adenomas, meningiomas, craniopharyngiomas and aneurysms, plays an important role in guiding treatment decisions. Modern imaging techniques are also important in evaluating the pituitary gland after surgery.

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
Brain Imaging
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic Stimulation (TMS).
