For CPT® coding, which term is used for imaging of the blood vessels?

Angiography is the correct term used for imaging of the blood vessels. This diagnostic technique involves the use of contrast material and X-rays to visualize the inside of blood vessels and organs, particularly arteries and veins. By administering contrast dye, healthcare providers can obtain detailed images that help identify blockages, abnormalities, or issues related to the vascular system. The procedure is crucial for diagnosing conditions such as aneurysms, thrombosis, or vascular malformations.

In contrast, echography refers to ultrasound imaging, primarily used to visualize soft tissues and organs rather than blood vessels. Tomography is a method that allows for cross-sectional imaging of tissues within the body, but it is not specific to blood vessels. Sonography is also another term for ultrasound, focusing on the use of sound waves to create images, not specifically for blood vessel imaging like angiography does.
