Transvaginal sonography (TVS) detects
structures using ultrasound. It gives a much clearer picture and is
therefore much better suited for detecting structures within the
abdominal cavity than an abdominal ultrasound. The intent of ovarian
screening is to detect ovarian cancers at the earliest possible stage
when they are most likely to be cured. The following links show a little
bit more about how we use TVS to catch ovarian malignancies.
