| 摘 要： | 目的探讨肝脏局灶性结节性增生(focal nodular hyperplasia,FHN)的超声影像特征。方法经病理诊断或其他增强影像学检查及随访证实的35例FNH患者共45枚病灶,均行二维灰阶超声和彩色多普勒超声检查,其中20例患者的20枚病灶进行了超声造影检查。结果二维灰阶超声表现主要为肝内低回声或偏低回声局灶性病灶(88.9%),而且界限显示欠清;彩色多普勒超声检查43枚(95.6%)显示病灶内的血流信号,37枚(86.0%)可见连续条状血流信号,25枚(67.6%)表现为"轮辐状";超声造影检查动脉早期20枚病灶均表现为整体高增强,其中14枚(70%)表现为轮辐状增强,门脉期11枚(55%)病灶中央或偏心部位出现无增强瘢痕的征象;延迟期15枚(75%)表现为等增强,4枚(20%)表现为高增强,1枚(5%)表现为低增强。结论二维灰阶超声和彩色多普勒超声联合应用可检测出典型病灶的部分特征,但都无法检测FNH的微血管灌注情况,而超声造影可检测到病灶动脉早期、门脉期、延迟期显著的病变特征,明显提高诊断准确性。 |
