title: [The appearance of parotid neoplasms on real-time elastosonography].
abstract: OBJECTIVE
  To evaluate the features of parotid neoplasms on real-time elastosonography.
  
  
  METHODS
  The elastograms of parotid lesions in 43 patients with 48 neoplasms were analyzed and classified into 5 grades, with pathologic diagnosis as the gold standard for comparision. The data was statistically analyzed with SPSS13.0 software package.
  
  
  RESULTS
  The elastographic grades of most benign neoplasms were I-II, while those of malignancies were III-IV. The elastographic grades of benign and malignant lesions were of significant difference (P<0.05).
  
  
  CONCLUSIONS
  Some typical features of different parotid lesions on elastosonography are found, which are useful for differential diagnosis of parotid lesions.
