Primary Outcome Measures:
  • Detection of Liver Metastasis during Operation [ Time Frame: During Operation ]
    Intraoperative Rate of Detection of Liver Metastasis compared to preoperative Imaging Analysis

Secondary Outcome Measures:
  • Comparison of Detection Rate for Liver Metastases of all imaging modalities [ Time Frame: 1 Week after Operation ]
  • Comparison of Sensitivity of all imaging modalities [ Time Frame: one Year ]
  • Comparison of Specicivity of all imaging modalities [ Time Frame: one year ]

Enrollment: 59
Study Start Date: December 2011
Study Completion Date: January 2015
Primary Completion Date: December 2014 (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
