title: [Solitary pulmonary nodules: detection, characterization, and guidance for further diagnostic workup and treatment].
abstract: OBJECTIVE
  The purpose of our study is to improve radiologists' understanding of the clinical issues involved in making a diagnosis and to guide further diagnostic workup and treatment of solitary pulmonary nodules (SPNs).
  
  
  CONCLUSIONS
  Information on the morphologic and hemodynamic characteristics ofSPNs provided by dynamic helical CT, with high specificity and reasonably high accuracy, can be used for initial assessment. PET/CT is more sensitive at detecting malignancy than dynamic helical CT, and all malignant nodules may be potentially diagnosed as malignant by both techniques. Therefore, PET/CT may be selectively performed to characterize SPNs that show in-determinate results at dynamic helical CT.
