| 目的 观察肝局灶性脂肪浸润与周围相对正常肝组织是否存在血流灌注的差异。方法 应用低机械指数对比脉冲系列成像技术分析20例25处肝局灶性脂肪浸润与周围相对正常肝组织,比较常规超声回声强度、定量分析其超声造影增强效应。结果 常规超声检查时,局灶脂肪浸润回声强度高于周围相对正常肝组织(P＜0.001);在超声造影25 s时局灶脂肪浸润增强强度低于周围相对正常肝组织(P=0.001),在60 s、120 s超声造影增强强度差异无统计学意义(P＞0.05)。结论 肝局灶性脂肪浸润与周围相对正常肝组织在动脉期可以存在超声造影血流灌注的差异。 |

| Objective To investigate the hemodynamic features of focal fatty infiltration (FFI) and adjacent liver parenchyma with contrast-enhanced ultrasonography (CEUS). Methods Twenty-five FFI lesions of the liver and adjacent liver parenchyma in 20 patients were observed with low mechanic index contrast pulse sequencing. Echogenicity intensity of conventional ultrasound was compared and contrast enhancement was quantitative analyzed. Results Compared with adjacent liver parenchyma, the intensity of FFI lesions in conventional sonography was significantly higher (P＜0.001). However, the signal intensity of FFI lesions in 25 of CEUS was significantly lower (P=0.001), but the intensity of FFI lesions in 60 s and 120 s of CEUS was not significantly different (P＞0.05). Conclusion Enhanced intensity in some of FFI lesions may be different from adjacent liver in arterial phase. |
