【摘要】 为评价多普勒能量显像（CDEI）对肾移植急性排斥反应（AR）的诊断作用，对57例肾移植患者进行了术后早期监测和追踪。发现根据肾内血管的显像水平可将CDEI分为5级，急性排斥反应的发生率与CDEI血流级别密切相关。CDEI比彩色多普勒血流显像（CDFI）提供了更为丰富的肾血流信息，有助于剔除以RI、PI值为诊断标准的假阳性和假阴性，提高对AR诊断的准确率。更多还原

【Abstract】 In order to evaluate the value of color Doppler energey imaging (CDEI) in diagnosis of acute renal allograft reception (AR), 57 cadaveric renal allograft patients were examined with CDEI and CDFI. According to the vasscular image level, CDEI maps were divided into five grades. The incidence of AR was highly correlated to the CDEI grading. Theresults suggested that CDEI, RI and PI were the sensitive diagnostic parameters Of AR. CDEI could improve the diagnostic accuracy by giving more informations about the kindey blood supply and excluding the false nagative and false positive results of RI and PI.更多还原
