CT
Triple rule out + lower limb venography (Contrast)
Also Known As:
Triple rule out + lower limb venography (Contrast)
About This Test
This combined study integrates a standard Triple Rule Out (TRO) CT angiography with a comprehensive lower limb venography to provide a detailed evaluation of both arterial and venous systems in one session. The TRO component assesses the coronary arteries, pulmonary arteries, and thoracic aorta to exclude critical conditions such as coronary artery stenosis, pulmonary embolism, and aortic dissection in patients with chest pain or suspected vascular emergencies. Along with this, contrast-enhanced lower limb venography evaluates the deep venous system of both legs, helping detect deep vein thrombosis (DVT), venous obstruction, or other circulatory abnormalities. By performing both studies together, clinicians gain a complete picture of thromboembolic risk—from the lower limbs to the lungs and heart. This combined protocol is especially useful in patients with symptoms suggesting possible pulmonary embolism originating from DVT. It enables faster diagnosis, reduces multiple scan requirements, and supports prompt treatment planning.

Frequently Asked Questions
Ans-CT scan uses X rays to create detailed images of the inside of the body.
Ans -No. It is completely painless. You just need to lie still..
Some scans need contrast dye for clearer images. Your doctor will advise based on your
condition.
condition.
Ans- Most scans take 5–10 minutes.
Ans-Yes. CT scan is a safe imaging test. However, it exposes you to a small dose of radiation. For most people, such a small potential risk far outweighs the benefits, in terms of saving your life. The radiation dose is controlled and kept within safe limits.
TAT Policy
The Turnaround Time (TAT) depends on the following factors:
- Registration date and time
- Type of scan or test
- Scan time or sample collection time
In uncommon circumstances, TAT may be delayed due to test complexity or reasons beyond our control. You will be informed of the estimated TAT at the time of registration.
