目的:分析彩色多普勒超声仪在脂肪肝中低回声病变的声像图特点及鉴别诊断意义。方法:对100例脂肪肝中的偏低回声病变进行仔细扫查,观察其发生部位、大小、形态、内部及后方回声和周围血管的血流情况。结果:本组100例脂肪肝中的低回声病变(肝化学性损害肝实质增粗)6例(6.00%),非均质脂肪肝60例(60.00%),肝血管瘤18例(18.00%),肝囊肿16例(16.00%)。均经CT或随访证实。结论:脂肪肝中的低回声病变大小形态多样,主要应与小肝癌仔细鉴别,彩色多普勒超声分辨率高,无创伤,可通过观察血流情况及定期随访进一步鉴别诊断。
Objective: To analyze the characteristics and differential diagnosis of hypoechoic lesions in fatty liver with color Doppler ultrasound. Methods: 100 cases of fatty liver in the hypoechoic lesions were carefully scanned to observe the location, size, shape, internal and posterior echo and the blood flow around the blood vessels. Results: Six cases (6.00%) of hypoechoic lesions (60.00%) with heterogeneous fatty liver and 18 (18.00%) hepatic hemangiomas were found in 100 cases of fatty liver. ), Hepatic cysts in 16 cases (16.00%). All confirmed by CT or follow-up. Conclusions: The size and shape of hypoechoic lesions in fatty liver are diverse and should be carefully distinguished from that of small hepatocellular carcinoma. The color Doppler ultrasound has high resolution and no trauma, and can be further differentiated by observing blood flow and regular follow-up.
