Target Volume Determination 2015

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.

The limited spatial resolution of PET particularly limits visualization of early- stage carcinomas with small volumes (Tis, T1 and T2).

The OVERALL primary oesophageal tumour detection rate

EUS is the preferred method for primary tumour staging

with PET-CT is approx. 92.7%
