Limitations of MRI for Staging
Nodal staging: Tumour may be present in normal sized nodes High incidence of enlarged reactive pelvic nodes High incidence of
Tumour staging: Varying ability to distinguish T2 (localised) from T3 (extracapsular) disease Sensitivity of T2-weighted MRI : 37-96% * DCE-MRI may improve tumour staging: Increased specificity for extracapsular extension +
microscopic nodal spread to surgically non-sampled sites
