Improving the diagnosis of liver cancer with Positron Emission Tomography (PET) scanners by applying mathematical models and using breathing motion correction methods

Interventions: PET scanning, kinetic analysis, respiratory motion correction. This involves 60 additional minutes of PET scanning (after the routine PET tracer injection up until the usual time of commencement of the routine PET scan at 60 minutes post injection). The information for kinetic analysis and respiratory motion correction are obtained during this 60 minute scan.
Primary outcome(s): Number of F18-Flourodexoyglucose (FDG) avid cancer secondaries detected in the liver with the modified method compared with standard FDG PET imaging.[Baseline only]
Study Design: Purpose: Diagnosis; Allocation: Non-randomised trial; Masking: Open (masking not used);Assignment: Single group
