Compare this waveform with that in Figure 3.12F . Note that the ratio of the EDV to the PSV is much lower in this waveform, with a resistive index of 0.8, suggesting the presence of parenchymal disease in the kidney. 图3.14段动脉血流频谱形态mid-pole右肾。与3.12F波形图比较。请注意，在这个波形，EDV/PSV比值较低，阻力指数为0.8，表明存在实质疾病的肾脏。 Figure 3.15 Axial view of proximal abdominal aorta with color Doppler flow demonstrating the origin of the celiac trunk(CA),which then bifurcates into common hepatic (CHA) and splenic (SA) arteries. 图3.15近端腹主动脉彩色多普勒血流轴向视图显示腹腔干（CA），动脉分叉后可见肝（CHA）和脾（SA）的声像。 Figure 3.16 Normal Doppler waveforms from mesenteric vessels. A: Superior mesenteric artery in the fast state, with high resistance pattern. B: Celiac artery in the fast state, with low-resistance pattern. C: Inferior mesenteric artery with high resistance pattern. 图3.16正常肠系膜血管多普勒波形。A：肠系膜上动脉在快速血流状态，高阻抗模式。 B：腹腔动脉在快速血流状态，低电阻模式。C：肠系膜下动脉，高阻抗模式。 Figure 3.17 Doppler waveform from celiac artery. The PSV is 200cm/sec and the EDV is 55cm/sec, indicating the presence of severe stenosis. Note the marked turbulence of flow demonstrated in the color Doppler picture above consistent with the presence of a significant stenosis. 图3.17从腹腔动脉多普勒波形看，PSV200cm/sec和EDV55cm/sec，说明存在严重狭窄。注意图片上方存在一个显著狭窄的彩色多普勒显示的流量显着动荡。 Figure 3.18 Two examples of Doppler waveforms from patients with superior mesenteric artery stenosis. A:The PSV is 275cm/sec and there is tur
