超声造影观察病灶的增强时相和方式，包括起始时间、达峰值时间、消退时间及病灶内部结构的增强表现。
Then the modality and phases of enhancement were observed, including the arrival time, the peak time, the washout time and the appearance of internal structures.
其定量灌注参数与对照组相比，肾皮质灌注曲线下面积增大、峰值强度减低、曲线上升支斜率增大、达峰时间延长，与对照组有显著性差异（P<0.05）；
The quantitative perfusion parameters of renal cortical perfusion AUC increased, PI reduced, A increased, TTP extension, and the case group was significant different from the control group(P<0.05);
