title: Positron emission tomography helps to diagnose tumor emboli and residual disease in choriocarcinoma.
abstract: BACKGROUND
  Positron emission tomography (PET) has been shown capable of identifying malignant tissues.
  
  
  METHODS
  WB-PET imaging in two women with metastatic choriocarcinoma is described.
  
  
  RESULTS
  In a woman with tumor emboli secondary to a choriocarcinoma, WB-PET was the only noninvasive investigation to differentiate between tumor and blood clots. Moreover, PET helped to localize residual tumor tissue in another woman with persisting high beta-HCG serum levels after chemotherapy.
  
  
  CONCLUSIONS
  WB-PET helps to localize tumor tissue in patients suffering from choriocarcinoma.
