"The cisterna chyli can be identified as a rounded-to-elliptical retrocrural structure with an average attenuation of 4 HU. There is no enhancement following intravenous contrast administration.For routine diagnostic CT, the lack of enhancement is a key characteristic of the cisterna chyli, helping radiologists distinguish this normal anatomical structure from potential pathology."
