Post treatment contrast enhanced SPGR
sequences were acquired which showed a non-perfused volume of 72cc (fig.
However, 3-dimensional SPGR
is not typically included in imaging protocols because of decreased contrast between the cartilage and the adjacent joint fluid, long imaging times, increased metallic artifact (in the case of a post-surgical knee), and uneven fat suppression, even though it is considered standard for morphologic imaging of cartilage.
