What are the two main types of angiography?

• A. Therapeutic and diagnostic angiography
• B. Preventive and interventional angiography
• C. Diagnostic angiography and interventional angiography
• D. Prophylactic and corrective angiography

Answer: (C)

The correct identification of the two main types of angiography as diagnostic angiography and interventional angiography highlights the fundamental aspects of the procedures performed in this field.

Diagnostic angiography is primarily used to visualize blood vessels and organs to detect any abnormalities. This involves injecting a contrast agent into the bloodstream, which then allows imaging techniques to capture detailed views of the vascular structure. It is crucial in diagnosing conditions such as blockages, stenosis, and other vascular diseases.

On the other hand, interventional angiography goes a step further by not only diagnosing but also treating certain vascular issues. This type involves minimally invasive procedures guided by imaging techniques, allowing healthcare professionals to perform interventions such as stent placements, balloon angioplasty, or even the direct removal of a clot.

The other options do not accurately reflect the primary types of angiography recognized in medical practice. While terms like therapeutic and preventive might suggest aspects of patient care, they do not define distinct categories of angiography practice as clearly as diagnostic and interventional do. The combination of diagnostic and interventional succinctly encapsulates the purposes and approaches utilized in modern angiographic procedures.
