1. Barium Enema Radiologic Evaluation of the Colon Presented by: [Your Name] Date: [Insert Date]

2. Introduction - Radiologic procedure to visualize colon and rectum - Uses barium sulfate contrast - Detects structural abnormalities and diseases

3. Indications - Colorectal cancer - Inflammatory bowel diseases - Polyps or diverticulosis - Chronic diarrhea or constipation - Intussusception - GI bleeding

4. Contraindications - Suspected or confirmed bowel perforation - Acute abdomen or severe colitis - Recent rectal surgery - Uncooperative/severely ill patients

5. Types of Barium Enema - Single-contrast: Only barium, detects large masses - Double-contrast: Barium + air, detailed mucosal view

6. Patient Preparation - Low-residue diet 1–3 days prior - Laxatives the day before - Clear liquids on procedure day - NPO after midnight - Bowel cleansing

7. Procedure Steps 1. Patient in left lateral position 2. Rectal tube insertion 3. Barium instillation 4. Air insufflation (double contrast) 5. Spot films 6. Post-evacuation film

8. Radiologic Findings - Colorectal cancer: Apple core lesion - Diverticulosis: Outpouchings - Ulcerative colitis: Lead pipe appearance - Polyps: Filling defects - Intussusception: Coiled spring

9. Advantages - Widely available and cost-effective - Good large bowel visualization - Less invasive than colonoscopy - Useful for non-cooperative patients

10. Limitations - Lower sensitivity for small polyps - No biopsy capability - Radiation exposure - Discomfort from prep and air insufflation

11. Complications - Abdominal cramping - Perforation (rare) - Barium impaction - Allergic reaction (rare)

12. Comparison with Other Modalities Feature | Barium Enema | Colonoscopy | CT Colonography ----------------------|--------------|-------------|------------------ Visualization | Good | Excellent | Very Good Biopsy Capability | No | Yes | No Radiation Exposure | Yes | No | Yes Invasiveness | Moderate | High | Low

13. Conclusion - Valuable diagnostic tool for colonic pathologies - Still relevant despite newer technologies - Essential knowledge in radiology practice
