FFR-CT analysis uses advanced technology to get more information from a CT scan of your heart to better understand disease that may be present in your coronary arteries. An FFR-CT analysis provides highly detailed information about your coronary arteries that was previously available only by undergoing an invasive procedure.
Why do I need FFR-CT?
If your doctor has diagnosed or suspects that you have coronary artery disease, chances are you will be scheduled for a CT of your heart. This is usually called coronary computed tomography angiography or CCTA. CCTA helps doctors see if there is narrowing or blockages in the arteries of the heart caused by coronary artery disease.
Once you have a CCTA, the radiologist who reads the exam may then request FFR-CT analysis if more detail is needed. FFR-CT technology creates a personalized, digital 3D model of your coronary arteries from the information in your CCTA. It shows how each blockage impacts blood flow to your heart. This information helps your doctor determine the next step in your treatment plan.
How it works
- Your doctor will order a CCTA test to look for blockages. If additional information is needed, the radiologist who reads the exam may order FFR-CT. This does not require another appointment and there is no additional risk to you.
- Using your CT scan, the FFR-CT technology creates a personalized, digital 3D model of your coronary arteries and calculates how much each blockage limits your blood flow.
- Your doctor receives a digital, color-coded 3D model of your coronary arteries. This information helps you and your doctor determine the next step in your treatment plan.
Are there any risks?
There are no added risks associated with FFR-CT. There are risks associated with the CCTA, which uses a higher dose of radiation than conventional X-rays. If the exam is medically necessary, the risk is quite small compared to the benefit of an accurate diagnosis or intervention.
