Endorectal and Endoanal Ultrasonography (UTZ)

Endorectal Ultrasound is a special ultrasound technique in which a transducer is directly inserted through the anus and into the patient's rectum. The sound wave echoes detected by the transducer are converted by a computer into an image. It is one of the most useful diagnostic tools for diseases of the anal and rectal regions of the body, especially for cancer screening and staging.
