目的分析颈部各类囊性病变的灰阶及彩色多普勒超声的图像表现,探讨高频超声的不同超声特征。方法分析107例各类颈部囊性病变的资料,并就灰阶及彩色多普勒超声的应用做了前瞻性研究,包括病灶内血流的丰富程度及分布方式、以及血流的各项指数测定。结果良性肿瘤性病变及类瘤样病变、恶性肿瘤的二维超声和彩色超声表现均有一定特点,多项血流指数测定无鉴别诊断价值。良性肿瘤性病变及类瘤样病变诊断正确率高,为91．1％(92／101),恶性肿瘤病变(癌性囊肿)诊断准确率低,为16．7％(1／6例)。结论高频超声检查是颈部各类囊性病变简便有效的诊断方法,尤其对良性病变。
Objective To analyze the gray scale and color Doppler echocardiography of various cystic lesions in the neck and discuss the different ultrasonic characteristics of high frequency ultrasound. Methods The data of 107 cases of various types of cervical cystic lesions were analyzed and prospectively studied on the application of grayscale and color Doppler ultrasound, including the degree and distribution of blood flow in the lesion and various aspects of blood flow Index determination. Results The benign neoplasms, tumor-like lesions and malignant tumors had some characteristics of two-dimensional ultrasonography and color sonography. There were no differential diagnostic value for multiple blood flow index. The diagnostic accuracy rate of benign tumor-like lesions and tumor-like lesions was high (91.1%, 92/101). The diagnostic accuracy of malignant tumor (cancerous cyst) was low, which was 16.7% (1/6). Conclusion High-frequency ultrasound is a simple and effective method for the diagnosis of various cystic lesions in the neck, especially for benign lesions.
