What is CT Venogaphy?
Computerized Tomography (CT) Venography is a diagnostic procedure in which a contrast material is injected and rotating beams of X-rays are used to create cross sectional images of the veins, which are then used to create a complete three dimensional image of the veins and blood flow patterns in them.
Why is CT Venogaphy done?
- • To monitor the condition of the veins • To detect the presence of blood clots or any blockade in the veins • To determine the pattern of varicose veins before a surgery • To locate a suitable vein for dialysis or bypass procedures • To help guide treatment procedures like grafts or stents
Preparation for CT Venogaphy
- Pregnant women should inform their doctor (and x-ray technician) as the radiations may affect the fetus. If needed, precautions can be taken to lower the radiation exposure to the fetus.
- Depending on the area to be imaged, you may be asked to wear a hospital gown at the time of the scan.
