What is a CT Head with Contrast?
A CT (Computed Tomography) scan uses X-rays and computer processing to create 3D images of your head and brain. The addition of contrast dye, usually administered through an intravenous (IV) line, enhances image clarity, allowing radiologists to visualize structures like:
- Brain tissue and ventricles
- Arteries and veins (with CT angiography)
- Tumors, abscesses, or infections
- Signs of internal bleeding or trauma
- Vascular malformations or aneurysms
This enhanced technique helps in identifying even subtle changes within the brain that may not appear in standard non-contrast scans.
When is a Contrast CT Head Scan Recommended?
Doctors may recommend a CT Head with Contrast for:
- Suspected stroke or aneurysm
- Evaluation of brain tumors or metastases
- Detection of vascular disorders (using CT angiography)
- Assessment of head injuries or fractures
- Investigation of severe headaches, seizures, or neurological symptoms
What Happens During the Procedure?
- You will receive a contrast dye through an IV injection.
- The scanner moves around your head to capture high-resolution images.
- You need to remain still during the scan, which takes about 10–15 minutes.
- After the procedure, you can usually return to normal activities unless otherwise advised.
Benefits of CT Head with Contrast
- Detects strokes, bleeds, or clot formations early
- Visualizes vascular blockages or leakages using CTA
- Provides faster and more accurate diagnosis compared to standard imaging
- Helps plan surgical or interventional procedures precisely
CT Angiography (CTA) of the Brain
CT Angiography is often performed along with a contrast-enhanced CT head scan. It maps brain arteries in detail to detect:
- Narrowing or blockage in blood vessels
- Aneurysms or vascular malformations
- Clot formation or blood flow disruption
CTA offers quick, non-invasive visualization of brain circulation, aiding in stroke evaluation and pre-surgical assessments.
Preparation and Aftercare
- Avoid eating or drinking for a few hours before the test if instructed.
- Inform the healthcare team about any allergies (especially to iodine) or kidney issues.
- Drink plenty of water after the procedure to help flush out the dye.
