1. CT pulmonary angiography
Given the history of chest pain and elevated D-dimer levels, CT pulmonary angiography may prove useful. Efforts directed at a tissue diagnosis at this point are premature. 18FDG-PET scan is potentially useful for staging lung cancer and evaluation of pulmonary nodules and thus may ultimately be of benefit for this patient but typically adds value after cross sectional imaging characterization. Enhanced chest CT is preferable to MR [with or without intravenous] for suspected lung parenchymal abnormalities.
