Reply to: Re: Intraoperative ultrasonography during planned liver resections remains an important surgical tool ((2007) 21: 1280–1283)

We thank Prof. Cerwenka for his informative and insightful comments regarding our article. He highlights the importance of high-quality preoperative imaging, and that oftentimes this necessitates repeating studies using liverspecific protocols. Contrast-enhanced liver ultrasonography looks promising but its use in the USA is still considered investigational. Overall, his clinical experience is very similar to ours. Despite the impressive advances in crosssectional imaging over the last decade, intraoperative liver ultrasonography still plays an important role in guiding the surgical management of many patients with both benign and malignant liver lesions.
