How do you evaluate a CT head?
Examine the brain for:
- Symmetry - make sure sulci and gyri appear the same on both sides
- Grey-white differentiation - the earliest sign of a CVA on CT scan is the loss of the grey-white interface on CT scan
- Shift - the falx should be in the midline with ventricles the same on both sides
How does a CT scan create its image of the brain?
The term “computed tomography,” or CT, refers to a computerized x-ray imaging procedure in which a narrow beam of x-rays is aimed at a patient and quickly rotated around the body, producing signals that are processed by the machine's computer to generate cross-sectional images, or “slices.”.
How is a CT scan done on head?
During a brain CT, the X-ray beam moves in a circle around the body, allowing many different views of the brain.
The X-ray information is sent to a computer that interprets the X-ray data and displays it in a two-dimensional (.

What area does a head CT scan cover?
CT and CAT scans are the same test.
Special X-ray technology gives your doctor a picture of your skull, brain, eyes, nasal passages, veins, arteries, and tissue.

What does a CT scan of the head show?
A CT of the brain may be performed to assess the brain for tumors and other lesions, injuries, intracranial bleeding, structural anomalies (e.g., hydrocephalus , infections, brain function or other conditions), particularly when another type of examination (e.g., X-rays or a physical exam) are inconclusive..

What is a CT scan used for head?
Computed tomography (CT) of the head uses special x-ray equipment to help assess head injuries, severe headaches, dizziness, and other symptoms of aneurysm, bleeding, stroke, and brain tumors.
It also helps your doctor to evaluate your face, sinuses, and skull or to plan radiation therapy for brain cancer..
What is CT head and NCCT head?
NCCT(Non-Contrast Computed Tomography) Head with Temporal Bone is an imaging procedure that provides detailed information about the brain structure and temporal bone.
NCCT Head provides a detailed picture of the structure of the brain as well as its tissues..

Approach Considerations.
Anesthesia is typically unnecessary with most CT scans.
The patient typically lies on his or her back with head in the midline position on a movable table that slides into and out of the doughnut hole.
An x-ray tube typically rotates around the patient's head..

An x-ray tube typically rotates around the patient's head. - Brain CT scans
A CT scan uses X-rays to produce images, unlike an MRI scan which uses magnetic fields and radio waves. - CT images of the brain are conventionally viewed from below, as if looking up into the top of the head.
This means that the right side of the brain is on the left side of the viewer.
The anterior part of the head is at the top of the image. - Side effects and risks for a cranial CT scan involve discomfort, exposure to radiation, and allergic reaction to the contrast dye.
Discuss any concerns with your doctor before the test so you can assess the potential risks and benefits for your medical condition.
