Overview
CT scan
CT is the modality of choice for staging of the disease by identifying primary tumour, assessing local, nodal and distant spread.
Demonstration of lesions facilitated by negative contrast agents (water):
- Intrinsic mass with a short segment of bowel wall thickening.
- Invasion of retro peritoneal fat planes, pancreatic and biliary duct, vascular encasement, lymph nodal and distant metastases is common in later stages.
