Computed Tomography (CT) – Head – To Capture Images Of The Brain
Computed Tomography (CT) – Head is a noninvasive medical test that provides detailed information on head injuries, stroke, brain tumors and other brain diseases.
Computed Tomography (CT) – Head Is Performed To Detect:
- Detect brain injury, skull fractures and bleeding in patients with head injuries
- Examine bleeding caused by a ruptured or leaking aneurysm with a sudden severe headache
- Examine blood clot or bleeding within the brain shortly after a patient exhibits symptoms of a stroke.
- Detect a stroke (a new technique called Perfusion CT is used)
- Detect Brain tumors
- Diagnose diseases of the temporal bone on the side of the skull causing hearing problems
- Plan radiation therapy for cancer of the brain or other tissues.
- Guide the passage of a needle used to obtain a tissue sample from the brain
- Evaluate the extent of bone and soft tissue damage in patients with facial trauma, and planning surgical reconstruction
Some Of The Benefits Of This Technique Are:
- This medical test is widely available and is performed in a relatively short time at a reasonable cost as compared to MR imaging.
- It readily detects injuries and bleeding
- It provides detailed images of bone, soft tissue and blood vessels.
- The exam is usually used as an initial study for stroke detection
- CT is the preferred method for rapidly screening trauma victims to detect internal bleeding or other life-threatening conditions.
- Depicts brain blood vessels, revealing aneurysms and occlusion.
However, there is always a slight chance of cancer due to excessive exposure to radiation. As compared to MR imaging, the precise details of soft tissues of the brain are less visible on CT scans and is not sensitive enough to detect inflammation of the meninges.
