What is the transformation zone in the ultrasound?

I need to know what the transformation zone is on an ultrasound.


Answer by  worker5560 (37)

Ultrasound uses sound waves to produce images of organs in the body. Transvaginal ultrasound is performed to measure the length of the cervix which is a critical predictor of preterm birth, with the risk increasing as the cervix shortens. The cervical length decreases immediately after excision of the transformation zone.


Answer by  smmacdo (96)

The transformation zone is the the area that cells changes from columnar to squamous. It moves from the outer surface of the cervix to the cervical canal with age.


Answer by  Ken99 (281)

The transformation zone refers to an area in the cervix which migrates with age from the outer surface of the cervix along the cervical canal. This area is where cells change from columnar to squamous.


Answer by  Taran (716)

There is excellent correlation between ultrasound and ruler measurement of the cervix. There is significant cervical length shortening after LETZ, but further ,needed to see whether this persists or leads to pregnancy complications. To evaluate regeneration in cervical craters following large loop excision of the transformation zone (LLETZ) and to investigate possible differential healing patterns depending on the cone's size.
