CT Brain Angiography Test

Your doctor has advised you to have computed tomography angiography (CTA) of your brain. A CT scanner combines a high-tech X-ray scanner with sophisticated computer analysis to provide detailed, 3D images of blood vessels in your body, such as those in your brain, neck, kidneys, and legs. It can be used to identify weakened arteries or veins and to visualise blood flow. CT Angiography provides your doctors with more precise images of your blood vessels than MRI or ultrasound technology.

Before you arrive for your test, keep the following points in mind:

• Wear clothing that can be easily changed because you will be required to wear a hospital gown for your exam.
• All jewellery and valuables should be left at home.
• Please bring any orders from your doctor with you.
• Though we do not anticipate any delays in your exam, please bring a book, magazine, or music player to keep you entertained while you wait.

Later, your technologist will explain your procedure and answer any questions you may have while positioning you on an exam table.

If contrast dye is used, it will be administered through your IV.

During the injection, you may feel warm all over your body and have a metallic taste in your mouth. This is typical.

Please notify the technologist immediately if you experience any itching, sneezing, nasal congestion, scratchy throat, or swelling of your face.

The exam table will slide into the scanner, covering only the area of your body being studied. The scanner is open on both sides, allowing you to see out.

During your exam, the technologist will always be able to see and hear you.

You may be asked to hold your breath for a few seconds while the scanner takes a series of images. The actual acquisition of images takes very little time.

The images will be reviewed, and some may be repeated if necessary.

This procedure usually takes between 15 and 30 minutes. Your total time commitment will be approximately one hour and fifteen minutes.

After the test you can resume your regular diet.

If you had a contrast dye injection, you should drink six to eight glasses of water to flush it out of your system.

An imaging physician will examine your images and report their findings in writing. This report will be sent to your doctor within 24 hours. Some scans necessitate additional computer processing and may take longer to analyse.

The results of your exam will be communicated to you by your physician.

A CT Brain Angiography is typically performed in a hospital's radiology department or an outpatient imaging facility. So, for the best services and reliable results, schedule your test at Ganesh Diagnostic in Yamuna Vihar.
