title: Fused functional-anatomic images of metastatic cancer of cervix obtained by a combined gamma camera and an X-ray tube hybrid system with an illustrative case and review of the 18F-fluorodeoxyglucose literature.
abstract: BACKGROUND
  18F-Fluorodeoxyglucose (FDG) assessments have provided clinically important information in cervical cancer. FDG studies can now be performed by both dedicated PET systems and by new-generation gamma cameras. Hybrid systems which consist of positron emission tomography (PET) or a gamma camera with X-ray for fusion of functional-anatomic data without changing the patient's position are now available.
  
  
  METHODS
  A woman with newly diagnosed cervical cancer underwent preoperative FDG studies using a hybrid gamma camera. In addition to the known primary tumor, FDG detected heretofore unidentified metastatic disease at the liver, bone, and para-aortic lymph nodes: the treatment approach was consequently altered to chemo- and radiotherapy. The fused images provided precise localization of the lesions, guiding bone biopsy and radiation field planning.
  
  
  CONCLUSIONS
  When PET is unavailable, a modified gamma camera can provide clinically relevant data in patients with cervical cancer.
