Overview

Colour doppler can help identify abnormal positioning of the umbilical and portal veins that can indicate liver herniation. Findings can help differentiate between left and right sided CDH.

Other Imaging Findings

Colour doppler is a subtype of ultrasonography that detects the blood supply of a certain region. In the case of CDH and pregnancy, it is used to determine abnormal blood flow in the umbilical and portal veins as well as the positioning. Any abnormal positioning can indicate liver herniation. Due to increased echogenicity of the lung and liver, doppler helps identify defects that may be missed upon normal ultrasonography.[1]
