Case Discussion

Colonic cancer is one of the top 3 tumors in the western world, afflicting nearly equally both males and females.

Endoscopy if the gold standard investigation with CT for staging of a confirmed tumor.   In the case of the rectal cancer subset, MRI is performed for local staging.

With the additional advent of CT virtual colonoscopy the scope and role of barium enema is more limited, but often plays a role in failed colonoscopy, in both delineating the primary tumor and any synchronous disease.

The smorgasboard of imaging offerings if often to a degree dicatated by local practice/institution.
