Lung Cancer: PET, Perfusion CT, and Functional MR Imaging

Lung cancer is a common malignancy and an estimated 228,190 new cases will be diagnosed in the USA in 2013 (American Cancer Society www.cancer.org). Imaging has an important role in the detection, diagnosis, and staging of the disease as well as in assessing response to therapy and monitoring for recurrence after treatment. This chapter will emphasize the appropriate use of positron emission tomography (PET-CT) in the management of patients with lung cancer and will briefly review new techniques that can be used to evaluate patients with lung cancer such as perfusion CT and functional MRI.
