✦ Synopsis

Abstract

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. © 2007 Wiley Periodicals, Inc. J Clin Ultrasound, 2007
