To establish the effectiveness of color Doppler and power Doppler ultrasound (US) in identifying the arterial supply of the femoral head in newborn.
Sixty normal hips in 30 newborns (mean age: 22 days) were imaged with a 7 MHz transducer. The presence and Doppler characteristics of flow in the branches of the inferior and superior arterial groups were documented according to the anatomic description of Lagrange and Dunoyer.
The arterial flow within the chondroepiphysis from the inferior and superior branches was visualized in 100% and 91% cases, respectively. The transversal trochanter major incidence was the most adequate. Abduction without stress did not induce modification of the arterial supply.
Visualization of femoral head vascularity with Power Doppler and color Doppler US is feasible and consistent in the majority of healthy neonates.
确定彩色多普勒和能量多普勒超声（US）在识别新生儿股骨头动脉血供方面的有效性。
使用7MHz探头对30例新生儿（平均年龄：22天）的60个正常髋关节进行成像。根据拉格朗日和迪努瓦耶的解剖学描述，记录下、上动脉组分支内血流的存在情况和多普勒特征。
分别在100%和91%的病例中观察到了来自下、上分支的软骨骨骺内的动脉血流。大转子横向发生率最为合适。无应力外展不会引起动脉血供的改变。
在大多数健康新生儿中，使用能量多普勒和彩色多普勒超声观察股骨头血管情况是可行且一致的。
