Table 1. Examples of CTS and PET-CT report findings and categorisation of changes in MDT decision making.

Example CTS report	Example PET-CT report	Influence on MDT decision making
Distal oesophageal thickening, extension into gastroesophageal junction, no mediastinal involvement, no metastasis	Oesophageal carcinoma, no lymphadenopathy, no distant metastasis	No change in recommendation: PET-CT confirmed findings of the CTS
Distal oesophageal tumour, small volume lymphadenopathy in the chest and abdomen of uncertain significance	Single small circumferential distal oesophageal tumour	Change in recommendation: PET-CT showed no metastases where the CTS raised this possibility
Junctional tumour, no evidence of lymphadenopathy or disseminated disease	There are bone metastasis and contiguous nodal disease at upper oesophagus	Change in recommendation: PET-CT showed metastases where the CTS did not
Gastro-oesophageal junctional tumour with locoregional lymphadenopathy but no metastatic disease	Large gastro-oesophageal carcinoma, FDG avid mass projecting from lower lobe of caecum, which could represent malignancy	Change in recommendation: PET-CT prompted additional staging investigations

Abbreviations: CTS=computerised tomography; FDG=fluorodeoxyglucose; MDT=multi-disciplinary team; PET-CT=positron emission tomography-computed tomography.
