The root ligaments of the meniscus have an essential
role in maintaining the mechanical integrity of the
knee. It is possible to demonstrate tendons and
ligaments as high signal structures using 3D UTE
subtraction images in which short T2 tissues are
highlighted. In order assess whether this was feasible
and whether contrast administration would be detectable
over time we studied a volunteer before and after
injection of gadolinium. The root ligaments can be
readily demonstrated and can be identified by their
cross section appearance, internal structure and
location.
