Overview

MRI, although probably more sensitive that CT, is nonetheless still far from perfect with a sensitivity of only 67% 2. This is largely a result of the fact that as many as half involved nodes found histologically following surgery, being less than 3 mm in diameter 2.
As discussed above, nodes have a tendency to become cystic. The cystic component will have near-fluid attenuation. The solid metastatic component will appear 2:
