Description
Sample Required:
No sample is required for CT Angiography – Brain/Head. This imaging test involves the use of X-rays with the administration of contrast material to visualize the blood vessels in the brain and head.
Test Time:
The CT Angiography – Brain/Head procedure typically takes approximately 30 to 60 minutes, depending on the specific details of the study.
Test Normal Range:
There is no specific normal range for CT Angiography – Brain/Head results. The images are interpreted by a radiologist or healthcare provider to assess the blood vessels in the brain and head and detect any abnormalities.
What is the Test?
CT Angiography – Brain/Head is a diagnostic imaging test that utilizes X-rays with the administration of contrast material to visualize the blood vessels in the brain and head. It provides detailed images of the vascular structures.
Test Procedure:
During CT Angiography – Brain/Head, the contrast material may be injected into a vein before the CT scan. The patient will lie on the CT examination table, and X-ray beams will be used to create detailed images of the blood vessels in the brain and head.
When to Take the Test:
CT Angiography – Brain/Head may be ordered by healthcare providers to assess blood flow, detect vascular abnormalities, or investigate conditions affecting the brain and head.
Who Should Take This Test:
Individuals with specific concerns about blood vessel function in the brain and head, such as aneurysms or vascular diseases, may be candidates for CT Angiography – Brain/Head. This test provides detailed imaging for a comprehensive vascular evaluation.
Precautions for Exceptional Cases (Pregnancy, etc.):
If you are pregnant or suspect you might be pregnant, it is important to inform the healthcare provider before the test. Special precautions may be taken, and the use of contrast material will be carefully considered.
