| 目的 阐述腮腺肿瘤的超声图像特征,探讨B 超对腮腺肿瘤定位、定性的价值。方法 应用高频(7.5MHz,10MHz) 探头B型超声对56 例腮腺肿物(其中良性25 例,恶性31 例) 进行超声定位、定性。结果 超声对0.5cm 以上的囊性肿物及0.7cm 以上的实性及混合性肿物均可显示,对腮腺良性肿瘤的诊断准确率为84.0%,对腮腺恶性肿瘤的诊断准确率为77.4%,总的鉴别诊断率达80.4% .根据超声图像无法定性者为19.6 % .结论 B 超是一种安全、简便、有效的诊断方法,对腮腺占位病变的诊断准确率较高,可作为常规检查手段。若与组织定量分析法及细针吸细胞学检查相结合,对肿物进行定位、定量、定性,将会使诊断水平进一步提高。 |

| Purpose To distinguish diagnostic value of B-ultrasonic machines in parotid gland. Methods 56 patients (25 benigns and 31 malignants) were determined the location and quality of parotid masses with high frequency probe,7.5 MHz and 10 MHz. Results The ultrasound can identify those cystic masses larger than 0.5 cm in diameter,and solid and fixed tumors larger than 0.7 cm in diameter. The accuracy for the diagnosis of parotid benign tumor is 80.0% and that of parotid malignant tumor 77.4%. The general accuracy of differential diagnosis is as high as 80.4%,while the quality of 19.6% of the cases studied can not be determined by ultrasonic diagram. Conclusion The B-ultrasonic machine is a safe,simple and effective medical instrument,with high accuracy in the diagnosis of space occupying lesion of parotid gland. Therefore,it can be used as a means of routine examination. If combined with the tissue quantitative analysis and fine needle aspiration cytological examination,the diagnostic accuracy for the determination of location,quality and quantity of masses can be further improved. |
