到底怎么鉴别？一文读懂！

鉴别诊断：T2高信号中心瘢痕

Differential Diagnosis：T2 Bright Central Scar

① T2高信号并更高信号中心瘢痕，外周结节样强化，持续渐进性强化

  • T2 bright lesion

  • T2 brighter scar

  • Peripheral nodular enhancement

  • Persistent enhancement

巨大及中等大小的血管瘤 

Giant and a mid-size hemangioma

②T2等信号并轻度更高信号瘢痕，明显均匀强化，廓清至等信号

  • T2 isointense

  • T2 slightly brighter scar

  • Homogeneous enhancement

  • fades to isointensity

局灶性结节性增生（FNH）

Focal nodular hyperplasia

③ T2轻度高信号并更高信号瘢痕，不均质强化，廓清并包膜强化

  • T2 slightly bright lesion

  • T2 brighter scar

  • Heterogeneous enhancement

  • Washout with capsular enhancement

肝细胞癌（巨块型）

Hepatocellular carcinoma

小结

  • 评估T2WI：第一例，高信号病变+更高信号瘢痕。第二例，等信号病灶+高信号瘢痕。第三例，较高信号病灶+更高信号瘢痕。

  • 评估增强动脉期：第一例，外周结节样强化。第二例，除瘢痕之外明显均匀强化。第三例，较明显不均质强化。

  • 评估增强门脉期：第一例，向心性渐进性强化。第二例，廓清至等信号。第三例，廓清、假包膜强化。

  • 评估增强延迟期：第一例，持续强化并中心瘢痕不强化。第二例，等信号并中心瘢痕及分隔强化。第三例，廓清、假包膜强化。

肝细胞癌，主要特点：增强扫描“快进快出”、中心裂隙状坏死、明显弥散受限、假包膜。

FNH，主要特点：T2WI等或略高信号，中心更高信号瘢痕，动脉期明显全瘤性强化，延迟期等或稍高信号，肝胆期呈等信号。

肝转移瘤（肝穿：小细胞癌；另发现左下肺占位），主要特点：小类圆形、边界清楚，弥散受限，乏血供，延迟期中心强化。
