CT Scan Review
He examines the scan for wall thickening, fluid collections, masses, strictures, or signs of obstruction.
Laboratory and Stool Tests
Blood work to assess for infection, inflammation (CRP/ESR), anemia or liver enzyme abnormalities.
Stool studies to detect occult blood, pathogens, or inflammatory markers.
Endoscopic Assessment (if indicated)
When imaging suggests mucosal disease, he performs an upper endoscopy or colonoscopy to visualize the lining, obtain biopsies, and rule out ulcers, polyps, or malignancy.

Frequently Asked Questions
What does an abnormal CT scan mean?
It means something unusual was found on your digestive imaging—such as thickened bowel walls, fluid collections, or unexpected masses.
Is an abnormal CT always cancer?
No. Many non-cancerous conditions—like IBS, infections, or inflammatory bowel disease—can also cause abnormal findings.
Can IBS show up on a CT scan?
Yes. IBS may present as mild bowel wall thickening or changes in gas pattern, though it's often a diagnosis of exclusion.
Are CT scans safe?
Yes. Modern scanners use low doses of radiation, and CT imaging is only ordered when the benefits outweigh the risks.
How quickly are CT results available?
Most CT scan reports are ready within 24 hours, though urgent studies can be interpreted sooner if needed.
Will I need contrast dye for my CT?
Sometimes. Contrast helps highlight blood vessels and inflammation; your doctor will decide based on your symptoms and medical history.
When should I see a GI specialist?
If you have persistent belly pain, bleeding, unexplained weight loss, or abnormal scan findings, you should consult a gastrointestinal specialist promptly.
