Purpose: To report contrast-enhanced sonography (CEUS) for solitary necrotic nodule (SNN) of the liver and to assess its clinical value.
Methods: 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.
Results: Lesions were depicted as perfusion defects throughout all phases on CEUS.
Conclusions: CEUS can be a convenient imaging modality for the differential diagnosis of SNN and may obviate the need for further imaging studies.
