超声造影结合新时相划分在肝脏局灶性结节性增生诊断中的价值

Contrast-enhanced ultrasound associating with new phases diagnosis of focal nodular hyperplasia of liver

目的探讨超声造影(CEUS)在诊断肝脏局灶性结节性增生(FNH)中的价值。方法回顾性分析了5例FNH的超声造影资料,并与CT增强或MRI进行了比较。结果CEUS能够优于CT或MRI连续观察病灶的动脉相、门脉相、实质相、延迟相的声像图变化,观察到FNH的典型表现动脉相由中心呈轮辐状增强,门脉相及实质相、延迟相持续增强,部分病例可有中央星状瘢痕。结论超声造影结合新的时相划分对于FNH具有较高诊断价值。

Objective To study the value of Contrast-enhanced Ultrasound in diagnosing focal nodular hyperplasia of liver （FNH）. Methods Five patients with FNH underwent CEUS, the cases were compared with contrast-enhanced CT and MRI. Results CEUS can continuely observe the display of the lesion in arterial phase ,portal phase, parenchyma and delayed phase, it was better than CT or MRI. And FNH has typical show, it rapidly enhanced spoke-wheel pattern in arterial phase, continuely enhanced in portal phase, parenchyma and delayed phase, some cases can show star-scar in the center. Conclusion CEUS associating with new phases is of high value in the diagnosis of FNH.
