Normal pituitary gland: 1. Macroscopic anatomy-CT correlation.

Volumetric evaluation of pituitary gland in dog and cat using computed tomography

The objective of this study was to evaluate the pituitary gland dimensions due to age and weight using computed tomography (CT) in dogs and cats. The CT images of pituitary gland were assessed in 11 client-owned dogs (six males and five females; age range, 1 to 9 years) and 15 client-owned cats (eight males and seven females; age range, 1 to 14 years) with no evidence of pituitary diseases. The...

Normal pituitary gland: 2. Microscopic anatomy-CT correlation.

Pituitary microadenomas may present with subtle or no mass effect. They may appear lucent, dense, or heterogeneous on computed tomographic (CT) images. The normal pituitary gland may also have a nonhomogeneous CT appearance with intermingled lucent and dense areas. This heterogeneity is related in part to microscopic variation within the anterior and posterior lobes. Thirteen autopsy specimens ...

A Spectacular Endoscopic Anatomy of the Pituitary Gland and the Circle of Willis in a Living Person

بررسی وجود انحراف طرفی ساقه غده هیپوفیز نرمال در افراد بالغ توسط MRI

    Background & Aim: Magnetic resonance imaging(MRI) in the coronal plane before and after contrast is currently considered to be the most specific and sensitive technique for imaging pituitary gland. However, because of the false negative results of this method in the detection of pituitary microadenomas and the importance of finding these microadenomas, infundibular deviation or tilt in MRI ...

Anatomical and cytohistological study of the pituitary gland in adult turkey

In order to conduct this study, eight adult turkey heads were obtained. Pituitary glands were harvested following cranial bones removal and examined morphologically and anatomically as well as topographically. Then, tissue sections were prepared and stained using Hematoxylin and Eosin, Alcian blue, orange G and periodic acid-Schiff staining techniques. The results showed that turkey pituitary g...
