1. CT NECK
ANGIOGRAPHY
BY VIRENDRA KAPGATE (BSC MRIT 4TH SEM )

2. WHAT IS CTA
•Computerized tomographic angiography is the
technique used to visualize blood vessels that have been
opacified by contrast media.
•CT Neck angio (Computed Tomography
Angiography) Neck Vessel is an imaging procedure
that uses a rotating x-ray beam to take detailed
images of blood vessels present in the neck region.

6. PATIENT PREPARATION
• Ask the patient about the history of the disease
• Like diabetes,allergy of contrast etc
• Tell the patient to remove metal ornaments (example
earrings,chainEtc)
• Explain the procedure to the patient
• Take consent from the patient for the procedure
• NBM 4HR prior to examination
• Check the creatine level (normal range 0.6to 1.5 mg/dl ).

7. EQUIPMENT
•CT scan machine
•Pressure injector
•Contrast media (iodinated 70-100ml)
•10ml syringe
•Normal saline
•IV Cannula 18 gauge

9. PATIENT POSITION
• Place the patient in supine position on the midline of CT scan
table.
• Insert the IV Cannula in the patient Vein
• Load the contrast media in the pressure injector
• Patient both hand must be toward the body.
• Insert the extension tube of pressure injector into cannula.
• Centering point beam is directly perpendicular to the mandible.

11. SCAN TECHNIQUE
• Topogram ( scout) should be taken for the examination of whole
carotid artery the scan taken from Nasion to arch of aorta .
• Kvp- 120 and MA-10 Should be used
• Premonitoring for trigger
• Then make the planning on scout for artery and venous scan
inject the contrast by pressure injector intravenously start scan
at a time
• Contrast flow 3-3.5ml/second

12. •Artries phase take 15-18 second and
• venous phase complete in 30 second
•Use 120kvp and 50MA
•Follow the principle of ALARA
•ALARA “as low as reasonably achievable”
• Take the delayed after 3 minutes.

14. INDICATION
1. Suspected vasculitis (inflammation of the blood vessel walls)
2. For suspected abnormal blood vessels in the brain
3. For planning before carotid artery surgery
4. Ischemic stroke
5. Vasculitis (Vasculitis can cause vessel walls to thicken and narrow,
cutting off vital blood supply to tissues and organs.)
6. Foreign body

15. CONTRA INDICATION
1. Pregnancy
2. Allergy to contrast
3. Severe diabetes

16. AFTERCARE OF PATIENT
•Check the willingness of the patient
•Is there any allergic reactions like vomiting.
