EUS is the most
accurate T-staging
investigation (e.g.
accuracy of up to
95% for T3 and T4
disease)
CT makes a very
useful contribution to
the T-stage,
especially in
recognising T3
disease and alerting
to possible T4
involvement (e.g.
accuracy of 85% for
mediastinal
invasion )
PET does not have
any major role in T-
staging (e.g.
sensitivity of <50%
for T1).
Role is in N and M
staging
