Accuracy and Cost-Effectiveness of Dynamic Contrast Enhanced Computed Tomography in the Characterisation of Solitary Pulmonary Nodules 


A prospective, observational study to assess the accuracy and cost effectiveness of dynamic contrast enhanced computed tomography in the characterisation of Solitary Pulmonary Nodules. 


Primary Objetives: 

  • To determine with high precision, the diagnostic performances of DCE-CT and 18FDG-PET/CT in the NHS for the characterisation of solitary pulmonary nodules (SPNs).
  • To use decision analytic modelling to assess the likely costs and health outcomes resulting from incorporation of DCE-CT into management strategies for patients with SPNs.

Secondary Objectives:

  • To assess, within an NHS setting, the incremental value of incorporating the CT appearances of a SPN into the interpretation of integrated PET/CT examinations.
  • To assess whether combining DCE-CT with 18FDG-PET/CT is more accurate and/or cost-effective, in the characterisation of SPNs, than either test used alone or in series.
  • To document the nature and incidence of incidental extra-thoracic findings on 18FDG-PET/CT and DCE-CT undertaken for the characterisation of SPNs and model their impact on cost-effectiveness.
