分析病变处血流的搏动指数(PI)和阻力指数(R I)与病理组织学结果的关系。
Lesion vascularity, pulsatility index (PI), and resistive index (ri) of the vessels detected were analyzed. And correlated with histologic results.

各组间阻力指数（RI）、搏动指数（PI）无显著差异。
Resistance index(RI) and pulsatility index(PI) were not significantly different in different age groups.
