CT- Brain angiography is an imaging procedure that evaluates the blood vessels in the brain. A scanner is used to take images which are assembled into three-dimensional views of the blood vessels using state-of-the-art computer software. These 3-D models help the radiologist more accurately view the structure of blood vessels in diseases such as aneurysms, intracranial or extracranial vessel stenosis, and stroke.


Why is CT - BRAIN ANGIO (Carotid) done ?

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
  • An arm 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 the patient’s 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 internal injuries

Why is CT - BRAIN ANGIO (Carotid) ?

CT Angiogram (Carotid) is an X-ray test that uses a special dye and camera (fluoroscopy) to take pictures of the blood flow in the blood vessels of the head and neck. An angiogram of the neck (carotid angiogram) can be used to look at the large arteries in the neck that lead to the brain. CT angiogram of brain (cerebral angiogram) can be used to look at the veins or the four arteries (four-vessel study) carrying blood to the brain. During an angiogram, a thin, soft tube called a catheter is placed. into a blood vessel in the groin (femoral artery or vein) or just above the elbow(brachial artery or vein). The catheter is guided to the head and neck area. Then an iodine dye (CONTRAST material) is injected into the vessel to make the area show clearly on the X-ray pictures. The angiogram pictures can be made into regular X-ray films or stored as digital pictures in a computer. An angiogram can find a bulge in a blood vessel (aneurysm). It can also show narrowing or a blockage in a blood vessel that slows or stops blood flow. An abnormal pattern of blood vessels (arteriovenous [AV] malformation) or abnormal vessels near a tumor can be seen.
