Estimated Study Completion Date: December 2013
Estimated Primary Completion Date: March 2013 (Final data collection date for primary outcome measure)
Intervention Details:
    Procedure: Liver Surgery
    R0 Resection of Liver Metastases after Planning with preoperative imaging data and comparison with intraoperative contrast enhanced ultrasound
    Device: Contrast Enhanced Ultrasound
    The contrast enhanced Ultrasound imaging is performed before and during the operation using Sonovue contrast agent (2.5ml iv preop, 4.5ml iv intraop)
    Radiation: CT Scan (standard)
    A staging CT of the liver/abdomen with the minimal possible dosage for aquiring sufficent triphasic data in a 64-line helical scan
    Radiation: Primovist MRI (3 Tesla)
    an MRI scan of the liver with Primovist contrast agent including late phase as addition to the preop staging according to the protocol
