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.
