Questions and Answers
Transesophageal echocardiography (TEE) provides clearer images because ultrasound waves pass through more tissue.
False
A topical anesthetic agent and sedation are not used during TEE due to the lack of discomfort associated with the positioning of the transducer in the esophagus.
