Virtual surgical planning. a Axial enhanced CT image shows a right liver metastasis centred in segment V (arrow). The patient also had a metastasis involving segment VII (not shown). b Axial enhanced CT image of a different patient shows a left liver metastasis in segment III (arrow). c Three-dimensional rendering image shows surgical planning for complete right hepatectomy including tumour and hepatic structures in patient from a. d Three-dimensional rendered image shows surgical planning for segmentectomy of segment III for patient in b. Residual hepatic liver volume after both procedures was estimated to be 27%. Right portal embolisation was thus performed before right hepatectomy.
