CT Scan for Stroke

Diagnosing a Stroke with a CT Scan

A stroke is a severe condition that can negatively affect a person’s life, especially if left untreated. This is why it is essential to have an early diagnosis in order to reduce the patient’s chance of living with a disability. If you or your loved ones have recently had a stroke it would be a good idea to get a CT scan. This imaging test allows a clear view of the head, including tissue and blood vessels.

What causes a stroke?

Strokes are caused when the blood supply to the brain is stopped suddenly. This may be caused by either a blocked or burst blood vessel. Strokes can be either hemorrhagic or ischemic:

Hemorrhagic: This stroke is accompanied by a hemorrhage, in which a blood vessel bursts and bleeds into the brain. Treatment for hemorrhagic stroke involves lessening the pressure on the brain.

Ischemic: This stroke is a result of the blood supply to the brain’s tissue being restricted, which results in less oxygen. Treatment involves restoring the blood flow. 

Strokes may lead to physical disability, brain damage, and even death. In order to diagnose a stroke, a doctor may order a CT scan. If you are living in Bangkok, you may get a CT scan for stroke.

Why a CT scan?

A CT scan uses x-rays and computers in order to create multiple images of the head from various angles. Details of the image may include the size and location of the abnormalities within the brain, such as tumors or blood clots. A CT scan may also reveal infections, such as areas in the brain where tissue is damaged or dead due to the lack of blood flow.

Diagnosing a stroke using a CT scan can identify whether the stroke is hemorrhagic or ischemic, allowing the appropriate treatment to be used. There are certain treatments that are effective depending on if the stroke is hemorrhagic or ischemic. For instance, thrombolytic therapy is used to dissolve blood clots, however, this treatment is only appropriate for ischemic strokes.

Because of the clear images created through the CT scan, it can more accurately determine whether the symptoms are caused by other brain abnormalities. For instance, a brain tumor may mimic stroke symptoms.

During a CT scan, dyes are intravenously injected which highlight abnormal areas in the scan, allowing a clearer view of the head. Because CT scans use such a low amount of radiation, there are no side effects.

CT scans are one of the most common image tests ordered to test for strokes, as they are available at many hospitals throughout most hours of the day in Bangkok.
