Coronal CT (a) and WB-DWI/MRI b1000 (b) image of a 73 year old male patient with a primary tumour in the descending colon and synchronous peritoneal carcinomatosis. CT images estimated the PCI to be 7 (partially shown with the arrowheads in A as a hypodense thickening on the liver surface) and WB-DWI/MRI estimated a PCI of 19 (partially shown with the arrowheads in B as diffuse confluent metastases at the liver surface). The high PCI of 19 was confirmed during explorative laparotomy. The patient was deemed inoperable and received palliative chemotherapy
