Interventions
R0 Resection of Liver Metastases after Planning with preoperative imaging data and comparison with intraoperative 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)
A staging CT of the liver/abdomen with the minimal possible dosage for aquiring sufficent triphasic data in a 64-line helical scan
an MRI scan of the liver with Primovist contrast agent including late phase as addition to the preop staging according to the protocol
