摘要 目的探讨Sonovue(声诺维)超声造影对肾脏占位诊断的应用价值。方法22例经彩色多普勒超声诊断为肾脏占位的患者,用Sonovue对患侧肾脏进行超声造影,实时动态记录整个超声造影过程,观察注射造影剂前后的肾脏及局部病灶的超声造影声像图特征表现。结果超声造影后肾癌病灶内的血流信号明显增强,但是肿瘤内的血流灌注无论从时间上还是回声强度上都没有一定的规律和特点。1例转移性肾癌则是快进增强,持续时间长,即为快进慢出现象。肾错构瘤大部分不增强,小部分可有病灶内血流信号稍增强,但持续时间短。肾囊肿无增强,肾柱肥大则与肾实质增强消退一致。结论应用超声造影剂能显著增强肾肿瘤的血流信号,并有助于准确的评价肾肿瘤的血供状况,对肾占位的诊断与鉴别诊断有重要的意义。
