【摘要】 目的探讨3.0T超高场磁共振在肝脏局灶性增生中的诊断价值。方法收集我院经病理证实的19例FNH患者的影像资料,进行回顾性诊断分析,总结本病的MRI成像特点。结果病灶平扫:T1WI低信号4处、略低信号19处;T2WI略高信号20处,高信号3处,等信号1处,有7处病灶出现中央或偏心瘢痕。增强检查时,24处动脉期明显强化,静脉期和平衡期呈稍高/等信号表现,延迟扫描呈略高信号21处,等信号2处,略低信号1处。有11处病灶处可见瘢痕强化。结论 FNH的MRI表现具有一定的特征性,结合临床病史及相应实验室检查手段,多可做出正确的诊断。更多还原

【Abstract】 Objective Discusse the diagnosis value in hepatic focal nodular hyperplasia with 3.0T ultra high field magnetic resonance. Methods Collected pathologically confirmed FNH 19 patients, retrospectively reviewed imaging data, diagnostic analysis, summarized disease imaging features of MRI. Results Unenhanced lesion: low signal on T1WI4, slightly low signal on19; T2WI slightly high signal20, signal3, signal1, 7lesions appeared central or eccentric scar. Increased inspection, 24obvious enhancement in arterial phase, venous phase and equilibrium stages showed slightly higher performance/signal, delayed scan and slightly high signal21, signal2, slightly low signal on1. 11 lesions visible scar enhancement. Conclusion FNH MRI has certain characteristics, combined with the clinical history and laboratory examination means, can make the correct diagnosis.更多还原
