title: Scintimammography with technetium-99m tetrofosmin in suspected breast cancer.
abstract: BACKGROUND
  Scintimammography with Tc-99m sestamibi has recently demonstrated a clinical usefulness in the evaluation of patients with breast lesions. The aim of this study was to assess the potential role of scintimammography using Tc-99m tetrofosmin in the detection of breast cancer.
  
  
  METHODS
  Fifty-five patients (age range: 33-76 years) with suspicious breast abnormalities detected by mammography, and ten controls were examined. Dynamic images (1-20 min post-injection of the radiopharmaceutical) followed by three planar views were performed. Final diagnosis was achieved by hystology after surgery or excisional biopsy.
  
  
  RESULTS
  A total of 59 breast lesions were considered. The sensitivity of Tc-99m tetrofosmin scintimammography for detection of primary breast cancer was 93.1% (27/29) and the specificity was 93.3% (28/30). No focal uptake was observed in both breasts of the control population.
  
  
  CONCLUSIONS
  Tc-99m tetrofosmin scintimammography has high diagnostic accuracy in detecting breast cancer and may have a clinical role as complement to conventional mammography.
