Colon

X-ray

• Not indicated (see "General examination of abdomen and pelvis")

Replaced by colon CT, which gives a lower radiation dose and better diagnostics.

CT

• Screening for colonic polyps
• With familial polyposis
• Suspected malignant tumour
• Blood in faeces, with significant haemorrhaging, the patient should go directly for colonoscopy
• Stomach pains with suspect colonic pathology
• Change of frequency of bowel movement

NB: with suspected inflammatory bowel disease or familial polyposis the patient should be referred for colonoscopy.

MRI

• No indication
