What are Brain CT Scans?
A doctor or physician may order a CT scan of the head and brain to make detailed pictures and analyze the internal structure. Computerized tomography (CT) scanning is useful to get a very detailed 3D image of certain parts of the body.
The process begins by taking many different X-ray views at various different angles, which are then combined with the use of computer processing to create cross-sectional images of the bones and soft tissue inside of your body, including tissues inside of solid organ. Ordinary X-ray testing does not show clear images of soft tissue, so doctors often request CT scanning to get a good image of soft tissue including organs, muscles, blood vessels, nerves, and the brain. Sometimes a contrast dye is used as it shows up clearer on the screen.
Many parts of your body can be seen during a quality CT scan of the head and brain including the skull, brain, sinuses, and eye sockets. This type of scan is often referred to as a cranial CT scan, a brain scan, head scan, or skull scan.
Reasons for a Head and Brain CT scan:
CT scans are used for a multitude of reasons. They may be done to check for certain cancers in various different ways including to detect abnormal tumors, growths or lumps. They also identify the location of tumors, the stage of cancer, and where to perform a biopsy.
A head and brain CT scan can be used to guide doctors or surgeons during a procedure, such as a biopsy. They are important in planning for certain types of therapy and surgery, as well as in the aftermath to determine whether your body is responding to treatment.
CT scans can be used to detect cysts or infections in the body. They can also identify the bone structures within the body and can accurately measure the density of bone.
A CT scan is often used to quickly inspect a patient after an accident in order to identify traumatic head injuries or any other internal injuries.
A Head and Brain CT scan may help diagnose (find):
A cranial CT scan can diagnose various diseases, cancers, and infections.
CT scans of the head and brain may be requested if the patient has experienced an injury or is displaying symptoms such as constant headaches, hearing or vision loss, muscle weakness, or difficulty swallowing or speaking.
It may also identify the cause of fainting, change of mind function including behavior or thinking, or numbness and tingling. A head and brain CT scan are also used for pre-surgery planning and injuries following trauma.
A cranial CT scan can diagnose abnormal blood vessels, aneurysms, bone infection, brain damage, brain swelling, brain tumors, or a stroke.
