BACKGROUND AND PURPOSE: Knowing the normal imaging appearance of the pituitary
stalk is important for the diagnosis of pituitary infundibular lesions, and more accurate …

Purpose The pituitary or infundibular stalk is an anatomically important structure identified
routinely in radiologic imaging for the evaluation of pituitary and suprasellar lesions. The …

The size, shape, signal intensity, and enhancement pattern of the normal pituitary stalk were
determined retrospectively by review of MR images of 58 patients. The pituitary stalk was …

Context: Pituitary stalk lesions have various etiologies, often not clinically apparent.
Pathological samples from these lesions are rarely obtained, because of the critical location …

Object The normal pituitary bright spot seen on unenhanced T1-weighted MRI is thought to
result from the T1-shortening effect of the vasopressin stored in the posterior pituitary …

The pituitary gland sits in the bony pituitary fossa, which is superior to the sphenoid sinus.
The pituitary gland is an oblong structure that measures approximately 12 mm transversely …

Objective To investigate the role of T2-DRIVE MRI sequence in the accurate measurement
of pituitary stalk (PS) size and the identification of PS abnormalities in patients with …

BACKGROUND AND PURPOSE: High signal intensity (HSI) at the pituitary stalk is reported
in pituitary adenomas. Our purpose was to clarify how and when this HSI formed, its long …

Since the advent of magnetic resonance (MR) imaging, imaging has become an integral part
of the evaluation of patients with endocrinological abnormalities suspected to be of pituitary …

Purpose Pituitary adenomas are common CNS tumors that can cause endocrine dysfunction
due to hormone oversecretion and by mass effect on the normal gland. The study of pituitary …
