Non-Invasive CT Angiography of the Brain In Gurgaon
Are You Looking for CT Angiography of the brain in Gurgaon? Then you have come across the right place. First of all, we will see what CT Angiography is and some facts related to it.
So, let's dive in.
A brain computed tomography angiography (CTA) is a type of neurologic CT scan that involves fast CT imaging while IV contrast is injected into a vein in the arm. This procedure makes it possible to see how the organs' blood vessels are set up. It can also be used to look at vessels or plan surgery.
Most of the time, it is used to find a small aneurysm or arteriovenous malformation (an abnormal connection between blood vessels) inside the brain.
Your doctor has suggested that you get a CT angiography (CTA) of your brain or neck. A CT scanner takes detailed 3D pictures of your blood vessels, such as those in your brain, neck, kidneys, and legs, by using a high-tech X-ray scanner and complex computer analysis. It can be used to find weak spots in arteries or veins and see how blood moves through the body.
CT angiography gives doctors more accurate pictures of your blood vessels than either MRI or Ultrasound.
What happens during the procedure?
During the CTA of the brain, a patient can expect the following:
- The person is told to lie down on the exam table.
- If contrast is used, it will be given at a controlled rate by an automatic injection pump that is connected intravenously.
- Even though the table moves slowly at first, when the actual CTA is done, it moves very quickly.
- During the scan, the person being scanned may be asked to not breathe.
- Artefacts can appear on the images if the person is breathing or moving in any way.
The CTA test can be finished in just a few seconds. But the patient may be in the room for a long time. This delay can happen because the technologist needs time to position the patient on the table, check or place an IV line, do preliminary imaging to confirm the start and end points of the exam, and set up the scan and contrast injection settings based on the part of the body being imaged.
What the test will be like?
Some people might feel uncomfortable when they lie down on a hard table.
When contrast is put through a vein, you may have:
- Slight burning feeling
- Taste of metal in your mouth
- Your body gets hot and tingly.
- This is normal, and most of the time, it goes away in a few seconds.
Why the test is recommended:
CTA of the head can be used to find out why:
- Changes in how you think or act
- Words that are hard to say
- Dizziness or vertigo
- Double vision or vision loss
- Fainting
- When you have other signs or symptoms, like a headache,
- Loss of hearing (in some people)
- Sensations of numbness or tingling, usually on the face or scalp
- Problems with swallowing
- Stroke
- Transient ischemic attack (TIA)
Some of the benefits of brain CTA are:
Angiography may get rid of the need for surgery, but if it is still needed, the findings from a brain CTA can help the surgery be done more accurately if it is still needed. As the CTA can tell when blood vessels are blocked, it may be possible to treat the problem.
- When it comes to small blood vessels, the CTA may give more accurate information about the body than an MRI.
- Catheter angiography is slower, more invasive, and has more risks than CTA. In catheter angiography, a plastic tube called a catheter is inserted into the patient's major blood vessels (usually in the groyne) and a contrast material is injected while the patient is probably sedated or given general anaesthesia.
- The CTA test is cheaper than the catheter angiography test.
- After a CTA exam, there is no radiation left in the body of the patient.
Normal Results of the test
If there are no problems, the results are thought to be normal.
Abnormal results mean
- Abnormal blood vessels (arteriovenous malformation).
- When the brain bleeds (for example, subdural hematoma or an area of bleeding).
- Brain tumours or other growths (mass).
- Stroke.
- carotid arteries that are narrow or blocked. (Your brain gets most of its blood from the carotid arteries. They are on each side of the back of your neck.)
- The vertebral artery in the neck is too narrow or blocked. (Blood gets to the back of the brain through the vertebral arteries.)
- A hole in an artery's wall (dissection).
- A weak spot in the wall of a blood vessel that makes it balloon out or bulge (aneurysm).
After the Test
After the test, you may resume your normal diet. If you got a contrast dye shot, you should drink six to eight glasses of water to get it out of your body.
A doctor who does imaging will look at your pictures and write a report about what they see. This report will be sent to your doctor within 24 hours, most of the time. Some scans need more work from the computer, so analysing them may take longer.
The results of your exam will be given to you by your doctor.
