The OVERALL
primary oesophageal
tumour detection rate
with PET-CT is
approx. 92.7%
The limited spatial
resolution of PET
particularly limits
visualization of early-
stage carcinomas with
small volumes (Tis,
T1 and T2).
Another consequence
of the poor spatial
resolution of PET and
the poor contrast
resolution of CT, is the
limited role in
evaluating the depth
of invasion ( T-stage)
of oesophageal
cancers.
EUS is the
preferred method
for primary tumour
staging
