Arteriovenous fistulas are abnormal lesions in the blood circulation between arteries and veins. They can appear anywhere in the body, but are most common in the brain. If arteriovenous fistulas are not detected and treated, they can lead to heart failure, seriously affecting the patient's health.

Non-contrast intravenous magnetic resonance imaging participates in the diagnosis and monitoring of venous-related diseases such as arteriovenous fistula, thrombosis, malformations, etc. This is the most advanced method today and is applied by many high-quality facilities for diagnosis and treatment.
