| [ Summary ] | Barium enemas are a routine examination for colorectal diseases. However, they are also helpful to examine localization, size and relationship to adjacent bowels in lesions of the rectum and anal canal. CTs are also routinely performed for malignant diseases of the rectum and anal canal to evaluate local spreading, regional lymph node metastasis, and distant metastasis. Recently developed multi-slice CTs with three dimensional image analysis allow for examination of the lumen in the large bowel, and may be an alternative to barium enemas or endoscopy in selected patients. MRIs are superior to CTs in the diagnosis of the anatomical relationships of lesions to the mesorectum and pelvic floor structures. Recent advances in CTs and MRIs have made detailed and precise evaluation of lesions in the rectum and anal canal possible before surgical intervention. | |
