CAVAE is an acronym for the Central Auditory Venous Anatomy and Echocardiography. It is a medical imaging technique used to evaluate the anatomy of the central auditory venous system, which includes the veins that drain blood from the brain and inner ear. It is also used to assess the structure and function of the heart and its valves. CAVAE is a non-invasive procedure that uses ultrasound technology to create images of the veins and other structures in the body.
