title: Solitary necrotic nodule of the liver: contrast-enhanced sonography.
abstract: OBJECTIVE
  To report contrast-enhanced sonography (CEUS) for solitary necrotic nodule (SNN) of the liver and to assess its clinical value.
  
  
  METHODS
  CEUS was performed in 17 patients with pathologically proven SNN. Contrast pulse sequencing and the contrast agent SonoVue were used to depict lesion vascularity at a low mechanical index. The enhancement patterns were evaluated in real time.
  
  
  RESULTS
  Lesions were depicted as perfusion defects throughout all phases on CEUS.
  
  
  CONCLUSIONS
  CEUS can be a convenient imaging modality for the differential diagnosis of SNN and may obviate the need for further imaging studies.
