To report contrast-enhanced sonography (CEUS) for solitary necrotic nodule (SNN) of the liver and to assess its clinical value.
CEUS was performed in 17 patients with pathologically proven SNN. Contrast pulse sequencing and the contrast agent SonoVue were used to depict lesion vascularity at a low mechanical index. The enhancement patterns were evaluated in real time.
Lesions were depicted as perfusion defects throughout all phases on CEUS.
CEUS can be a convenient imaging modality for the differential diagnosis of SNN and may obviate the need for further imaging studies.
报告肝脏孤立性坏死结节（SNN）的对比增强超声（CEUS）检查，并评估其临床价值。
对17例经病理证实为SNN的患者进行CEUS检查。采用对比脉冲序列和超声造影剂声诺维，以低机械指数描绘病变血管情况。实时评估增强模式。
在CEUS检查中，病变在各期均表现为灌注缺损。
CEUS可为SNN的鉴别诊断提供一种便捷的成像方式，可能无需进一步的影像学检查。
