Abstract
Colon cancers are staged using CT as follows: oral administration of 1 l water to delineate the small and large bowel and 100–150 ml intravenous iodinated contrast medium injected at 3–4 ml/s. Multidetector CT scans are acquired at 20–25 s (chest) and 70–80 s (abdomen and pelvis) post-injection with sections acquired at 1.25–2.5 mm section thickness and reformatted in the axial, sagittal and coronal planes at 2–5 mm for viewing. The image analysis is performed on a workstation with three-dimensional reconstruction software. This enables the images to be viewed in the coronal and sagittal planes and also allows rotation of the images for optimum comprehensive analysis.
