Rotational angiography

Rotational Angiography

Rotational angiography (pronounced roh-tay-shuh-nuhl an-jee-og-ruh-fee) is a medical imaging technique used in the field of interventional radiology to visualize blood vessels and organs in the body. The term originates from the Latin rotatio meaning rotation, and the Greek angeion meaning vessel, and graphein meaning to write or record.

Definition

Rotational angiography involves the rotation of the X-ray source and detectors around the patient, capturing multiple images from different angles. These images are then reconstructed to create a three-dimensional (3D) representation of the patient's vascular system.

Procedure

The procedure begins with the insertion of a catheter into a blood vessel, usually in the groin or arm. A contrast agent is then injected through the catheter to highlight the blood vessels. The X-ray source and detectors rotate around the patient, capturing images from various angles. These images are then processed and combined to create a 3D image of the blood vessels.

Applications

Rotational angiography is primarily used in interventional radiology to diagnose and treat conditions affecting the blood vessels and organs. It is particularly useful in the treatment of aneurysms, arteriovenous malformations, and stent placement.

Advantages

Compared to traditional angiography, rotational angiography provides a more detailed and comprehensive view of the blood vessels. It allows for better visualization of complex vascular structures and can help guide interventional procedures.

Disadvantages

Potential disadvantages of rotational angiography include exposure to radiation and the risk of allergic reactions to the contrast agent. As with any invasive procedure, there is also a risk of infection or damage to the blood vessels.
