Abnormal results may include:
Air in sinuses will show up on a radiograph as black, but fluid will be cloudy or white (opaque). This helps the radiologist to identify fluid in the sinuses. In chronic sinusitis,...
the radiologist may also note thickening or destruction of the bony wall of an infected sinus.
Radiologists may recognize even tiny facial bone fractures as a line of defect.
Tumors may be visible if the bony sinus wall is distorted or destroyed. Abnormal findings may result in follow-up imaging studies.
Skull x rays may also detect disorders that show up as changes in bone structure, such as Paget's disease of the bone or acromegaly (a disorder associated with excess growth hormones from the pituitary gland). Areas of calcification, or gathering of calcium deposits, or destruction may indicate a condition such as an infection of bone or bone marrow (osteomyelitis).
There are a number of different types of bones in the body. This video explains how some of the various types of bones allow you to move and support the forces of walking and other activities.
A skull X-ray is a series of pictures of the bones of the skull. The nasal sinuses can also be viewed on a skull X-ray. Skull X-rays have largely been replaced by computed tomography (CT) scans.
X-rays are a form of radiation, like light or radio waves, that are focused into a beam, much like a flashlight beam. X-rays can pass through most objects, including the human body. X-rays make a picture by striking a detector that either exposes a film or sends the picture to a computer Dense tissues in the body, such as bones, block (absorb) many of the X-rays and look white on an X-ray picture. Less dense tissues, such as muscles and organs, block fewer of the X-rays (more of the X-rays pass through) and look like shades of gray on an X-ray. X-rays that pass only through air look black.
The most common spine procedure is Lumbar Disc laminectomy, with 185,651 performed in 2006. The second highest category is Cranial, with 592,443 procedures performed and the most common Cranial procedure is Supratentorial Craniotomy, with 55,578 performed.
