In summary, based on the authors' method, repeated measurements made from the biporion-dorsum sellae plane have proven precision and ...On a normal brain CT, you can see the back wall of the sella turcica—the dorsum sellae. On a CT scan, a normal adult sella contains low attenuation cerebrospinal fluid which sits on top of the pituitary gland. On computed tomography angiography (CTA) images, you can often see this normal low attenuation fluid anterior to the dorsum sellae.

More than fifty-seven percent of patients showed a form of anatomical variant: the most common form was the pneumatised pterygoid processes (39.6%), followed by dorsum sellae (32.9%) and clinoid processes (20.3%), without statistically significant differences between males and females (p > 0.01).颅脑CT解剖口诀 一节一环,三体二囊; 八池九面,三室四窦 具体解释 一节:基底节 一环:脑底动脉环 三体:垂体、松果体、胼胝体 二囊:内囊、外囊 八池:二桥环枕四裂脚大 九面:听眦蝶鞍三下上体顶卵园灰质象1.… CT scans were imported into the orthographic viewer and a threshold was selected so that there were no voids or soft tissue showing in the skull. Next, the coordinate system was defined with the dorsum sellae set as the origin. The vector from the dorsum sellae to the nasion was defined as the positive y-axis and theThe dorsum sellae is terminated laterally by the posterior clinoid processes.; The sella turcica is bound in front by the tuberculum sellae and behind by the dorsum sellae.; Completing the formation of the saddle posteriorly is the dorsum sellae, which is continuous with the clivus, inferoposteriorly.; Behind the dorsum sellae is a shallow depression, the clivus, which slopes obliquely ...

dorsum sellae and both posterior clinoid processes are considerable widened and stretched in the poste - rolateral direction. The accessory osseous formations of the dorsum sellae resemble butterfly wings or can be termed as the wings of the dorsum sellae. Bone overgrowth of the dorsum sellae was imagined by the micro-CT scans (Fig. 2).

This investigation was initiated to develop a reliable and simple computerized tomography (CT) method for evaluating the morphometry of the cranial cavity (CC) and caudal cranial fossa in the dog. We obtained linear, area, and volume measurements of the entire CC and the caudal fossa compartment in 24 dogs, using transverse and reformatted sagittal and dorsal CT images.
