Summary
Brief summary (as posted)
Contrast-enhanced intraoperative ultrasound (CE-IOUS) plays an increasingly important role in the surgical therapy planning of primary liver lesions as well as liver metastases. The present study was designed to evaluate the significance of CE-IOUS by specificity and sensitivity and particularly the impact it exerts on the surgical strategy. A secondary aim was assessing the outcome relevance of surgeries influenced by CE-IOUS.
