目的探讨彩色多普勒显像(CDFI)在肝血管瘤病人中的应用价值。方法采用美国terason HD 2000型彩色多普勒超声诊断仪,探头频率为3.5-5.0MHZ。对60例肝血管瘤的病人进行检查。结果(1)肝血管瘤中毛细血管瘤直径小于3cm的超声特征为:回声强,边界清晰,周边有回声强的光带。CDFI:瘤体内及周边均未探及血流信号。(2)肝血管瘤中海绵状血管瘤直径大于3cm的超声特征为:回声强、低或近等混合性,边界尚清。CDFI:瘤体内可探及散在的点状血流信号。PW:为静脉血流频谱,未测到动脉血流频谱,部分周边可探及绕性或稍被挤压的血管血流信号。(3)60例病人的肝血管瘤周边均未探及低回声的“声晕”及后方声影。结论肝血管瘤是肝脏肿瘤中的良性占位性病变,利用CDFI检查使肝血管瘤的诊断有新提高,提高肝血管瘤诊断率,能给临床提供较准确可靠的诊断依据。
Objective To explore the value of color doppler imaging (CDFI) in patients with hepatic hemangiomas. Methods US terason HD 2000 color Doppler ultrasound diagnostic apparatus, probe frequency 3.5-5.0MHZ. Sixty patients with hepatic hemangiomas were examined. Results (1) Hemangiomas in the capillary hemangioma diameter less than 3cm ultrasound features: strong echo, the boundary is clear, around the strong echo with light. CDFI: no detection of blood flow in and around the tumor. (2) Ultrasound features of cavernous hemangiomas larger than 3 cm in hepatic hemangiomas are: echogenic, low or near-mixed, borderline clear. CDFI: The tumor can be detected and scattered in the punctate blood flow signal. PW: venous flow spectrum, no measured arterial blood flow spectrum, part of the periphery can be found around and slightly squeezed vascular blood flow signal. (3) None of the 60 patients had hemorrhagic hepatic hemangiomas with hypoechoic “sound halo” and posterior sonography. Conclusions Hepatic hemangioma is a benign space-occupying lesion in liver tumors. Using CDFI to diagnose hepatic hemangiomas has a new increase, and to improve the diagnostic rate of hepatic hemangiomas, it can provide a more accurate and reliable diagnosis basis for clinical diagnosis.
