Abstract
Apparent diffusion coefficients (ADCs) of the brain lesions in primary angiitis of the central nervous system (PACNS) patients were analyzed in this study. The mean ADC ratios for acute/subacute phase lesions were significantly lower than that for chronic phase lesions. However, some acute/subacute phase lesions had elevated ADCs and these lesions disappeared overtime, implicating a nonischemic mechanism in PACNS.
摘要
本研究分析了原发性中枢神经系统血管炎（PACNS）患者脑病变的表观扩散系数（ADC）。急性/亚急性期病变的平均 ADC 比值明显低于慢性期病变。然而，一些急性/亚急性期病变的 ADC 值升高，这些病变随时间逐渐消失，提示 PACNS 中存在非缺血性机制。
