目的 探讨彩色多普勒超声在诊断低回声型血管瘤中的应用价值。方法 应用二维超声、彩色多普勒血流图 (CDFI)、彩色能量多普勒血流图 (PDI) ,结合脉冲多普勒频谱对 18例共 2 2个低回声型肝血管瘤进行研究。结果 CDFI对低回声型肝血管瘤内血流显示率 2 7.2 7% ,PDI对低回声型肝血管瘤血流显示率 90 .91%。动脉血流检出率为 2 2 .73%。“病灶染色” 9个 (40 .91% )。低回声型肝血管瘤血流呈低速 ,阻力指数 (RI) <0 .6(6 0 % )。结论 彩色多普勒超声对低回声型肝血管瘤的诊断和鉴别诊断有重要价值。
Objective To explore the value of color Doppler ultrasound in the diagnosis of hypoechoic hemangiomas. Methods Two-dimensional echocardiography, color Doppler flow imaging (CDFI) and color Doppler flow imaging (PDI) were performed in 18 cases of hypoechoic hepatic hemangiomas with pulsed Doppler spectra . Results The CDFI showed a rate of 7.27% in hypoechoic hepatic hemangiomas and the PDI showed 90.91% in hypoechoic hepatic hemangiomas. Arterial blood flow detection rate was 22.73%. “Staining” 9 (40.91%). Low echo hepatic hemangiomas showed low blood flow, resistance index (RI) <0.6 (60%). Conclusions Color Doppler ultrasound is of great value in the diagnosis and differential diagnosis of hypoechoic hepatic hemangiomas.
