Fig. 2

Transverse sections from a patient with gastroesophageal junction tumour with liver metastasis. On [18F]FDG-PET imaging, both the primary (a) and liver lesions (d) are visible. Whilst the primary oesophageal lesion is visible on the unfiltered [18F]FLT-PET imaging (b), visualisation is improved following application of the KSF (c). Liver metastases appear as an area of relative photopaenia (e) on [18F]FLT-PET imaging. Following application of the KSF, there is marked reduction of the background hepatic signal allowing for improved visualisation of hepatic metastases (f). Both lesions are also seen on baseline [18F]FDG-PET imaging (d)
