The high-intensity signal seen on MR images of the posterior pituitary has been the subject
of numerous reports, including an important one in this issue of AJNR [1]. In 1984, we …

Five different theories have been proposed to explain the high-intensity signals within the
posterior pituitary fossa seen on MR:(1) a paramagnetic effect of phospholipids in the …

Each month the American Journal of Roentgenology will republish online one of the 100
most-cited articles from its first century. A corresponding commentary in the print journal by a …

T1-weighted magnetic resonance (MR) images of the pituitary gland and sella turcica
routinely demonstrate a region of high signal intensity in the neurohypophysis. High …

[en] The investigation of pituitary pathology has undergone significant changes during the
past two decades. CT permitted direct visualization of the sella turcica and its soft tissue …

Purpose: To evaluate the consistency of fat in the high intensity signals of the normal
neurohypophysis and to differentiate the high signal of posterior pituitary from that of dorsum …

The posterior aspect of the normal sellar content usually displays high intensity signal on T1-
weighted images. The shape, size, and location of this high intensity seem to be compatible …

The radiologic changes that may be demonstrated in the sella are manifold and may be
expressions of intracranial, cranial or systemic disease. They frequently provide the key to …

Imaging of the sella turcica and of the pituitary visualizes changes in and around the sella
turcica that reflect intracranial conditions, not solely those of the pituitary itself. Importance of …

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 …
