Understanding your health can be challenging, especially when you’re introduced to medical terms like ‘angiogram’ and angiography.‘ If you are unsure whether these two are the same or different, you are not alone. Many people struggle to differentiate between them, but understanding their meanings can make a big difference when discussing treatment options with your doctor.
In this article, we will demystify the two terms and explain the differences between the two main types of angiography, helping you make more informed decisions about your heart health and diagnostics.
While the terms angiogram and angiography are often used interchangeably, there is a subtle difference between the two.
An angiogram specifically refers to the image or X-ray produced during the procedure. It provides a visual representation of the condition of the blood vessels after a contrast dye is injected, helping doctors identify any blockages or abnormalities. In contrast, angiography refers to the entire procedure that captures the resulting images.
In short, an angiogram is the diagnostic image, while angiography is the method used to generate that image.
Coronary angiography involves the examination of the coronary arteries to detect blockages, narrowing, or other abnormalities that could lead to heart disease or a heart attack. This procedure, however, can be categorised into two distinct methods.
Traditional coronary angiography, also known as catheter coronary angiography, is an invasive procedure where a catheter is inserted into a blood vessel, typically through the groin or wrist. From there, doctors use imaging to guide the catheter to the heart or other targeted arteries. Contrast dye is injected directly through the tube and real-time X-ray images are captured to examine the blood vessels.
Otherwise known as a cardiac CT scan, a CT coronary angiography is a non-invasive heart testing procedure that does not involve the insertion of a catheter, Instead, the contrast dye is injected into a vein, typically in the arm, and the scanner takes a series of CT coronary angiograms. These are then combined to produce a 3D image of the arteries.
Studies indicate that CT scans demonstrate a higher sensitivity but lower specificity compared to conventional invasive angiography. As such, CT coronary angiography may be more suitable for initial diagnosis as well as for ruling out significant blockages. However, invasive procedures may be recommended for more in-depth evaluation when symptoms are present, or when there is a need for immediate intervention.
Due to their non-invasive nature, cardiac imaging techniques are generally considered lower risk than the traditional method. This means that the risk of complications such as bleeding, infection, or vessel damage is minimal.
Ultimately, the decision between a CT scan or traditional angiography should be discussed and determined with your heart specialist. They will be able to conduct a comprehensive assessment of your health, medical history, and any underlying conditions to ensure the most suitable and safest approach.
In conclusion, understanding the differences between angiograms, angiography, and diagnostic heart procedures can help you feel more in control of your health. With this knowledge, you’ll be better prepared to have an informed conversation with your doctor and choose the option that best aligns with your individual needs and health goals.
