A cranial computed tomography (CT) scan is an imaging method that uses x-rays to create cross-sectional pictures of the head, including the skull, brain, eye sockets, and sinuses. See: Computed tomography
|
|
Computed tomography (CT) scans are completed with the use of a 360-degree x-ray beam and computer production of images. These scans allow for cross-sectional views of body organs and tissues. Computed tomography is also known as computerized axial...

A skull x-ray is a picture of the bones surrounding the brain, including the facial bones, the nose, and the sinuses. See also: Sinus x-ray
|
|
Skull x rays are performed to examine the nose, sinuses, and facial bones. These studies may also be referred to as sinus or maxilofacial x rays. X-ray studies produce films, also known as radiographs, by aiming x rays at bones and soft tissues of...
