What is angiography?

Angiography is a medical imaging test that uses X-rays and a special contrast dye to see inside blood vessels, highlighting blockages or narrow spots. Angiography in Mohali helps with knowing your right heart condition and how it can be treated the optimal way. The final picture or video created by this test is called an angiogram.

 

 

What is CT Angiography?

CT angiography (CTA) is a fast, non-invasive medical imaging test that combines a computed tomography (CT) scan with an injection of a special contrast dye. It produces detailed 3D pictures of blood vessels and tissues throughout the body to check for blockages, aneurysms, or other vascular issues. Angiography in Mohali can help with diagnosing and treating heart conditions like blocked or narrowed arteries, coronary artery disease, heart valve problems, blood clots, and structural birth defects.

 

What are the differences between angiography and CT angiography?

Angiography and CT angiography are mostly similar, except the part where CT angiography has an added machinery to it.The main difference between the two is that traditional angiography is an invasive procedure requiring a catheter inserted into an artery, while CT angiography is non-invasive and uses an intravenous (IV) line with a standard CT scanner. Traditional Angiography includes an invasive test where a long, thin catheter is threaded through a blood vessel usually from the groin or wrist up to the area being examined whereas CT Angiography A non-invasive test that requires only a simple IV line in the arm to inject contrast dye, followed by a computerized tomography (CT) X-ray scan. Angiography in Mohali can help figure out what's the right procedure for you.

Is angiography harmful for the heart?

Coronary angiography is generally a safe and routine procedure. Serious heart complications such as a heart attack, stroke, or dangerous rhythm changes are often outweighed by the benefits of the procedure. 

 

What is the recovery time for angiography?
