ABSTRACT
Objective To evaluate the applicative value of ultrasound elastography in diagnosis of focal lesions in the parotid and submandibular glands.Methods 30 patients(30 lesions) were scanned by real-time ultrasound elastography and were analyzed in elastography evaluated criteria (5 score method).All the results were compared with the pathological types.Results The elastographic grades of most benign nodules were 1 - 3,while most of malignancy were 4 - 5.The elastographic grades of benign and malignant lesions were of significant difference statistically( P <0.01 ).If elastographic grade 4 or 5 were diagnosed as malignancies,the sensitivity,specificity and accuracy for diagnosing malignant l(e)sions in the parotid and submandibular glands were 72.73 %,84.21 %,80.00 %,respectively.Conclusions Ultrasound elastography is useful in the differential diagnosis of focal lesions in the parotid and submandibular glands.
