About The Test

A CT ABDOMEN & LOWER THORAX is a painless, high-resolution imaging test that captures detailed cross-sectional pictures from your diaphragm to your pelvis. At Cadabams Diagnostics, advanced 128-slice scanners deliver crisp images in under 10 minutes, helping doctors detect, stage, and monitor a range of abdominal and chest conditions quickly and safely.

2. What Is a CT ABDOMEN & LOWER THORAX?

Computed Tomography (CT) uses low-dose X-rays and computer processing to create 3-D images of organs, blood vessels, and bones.
- Scope: Covers the lower chest (base of lungs) to the pelvic floor.
- Contrast option: Oral and/or IV dye improves visibility of soft-tissue structures.
- Typical duration: 5–15 minutes, depending on the protocol.

3. When and Who Needs the Scan?

Your doctor may order a CT ABDOMEN & LOWER THORAX if you have:

  • Unexplained abdominal pain or weight loss
  • Suspected kidney stones, appendicitis, or diverticulitis
  • Trauma after an accident
  • Persistent cough or lower-lung abnormalities
  • Follow-up of known cancers (e.g., lymphoma, colorectal)

List of Parameters

  • Liver size, density, masses
  • Gallbladder wall thickness, stones
  • Kidney stones, hydronephrosis
  • Pancreatic duct calibre
  • Aortic diameter (aneurysm screening)
  • Lung bases for nodules or consolidation
  • Lymph nodes >1 cm
  • Bowel wall thickening or obstruction

Why This Test

  • Identify cause of acute or chronic pain
  • Detect infections such as abscesses
  • Evaluate injuries after blunt trauma
  • Stage cancers and plan biopsies
  • Monitor treatment response

When to Take Test

Benefits

Benefits of Taking the Test

  • Sub-mm resolution for early lesion detection
  • AI-enhanced dose reduction—up to 40 % less radiation
  • Same-day reporting for urgent cases
  • Comfortable wide-bore scanner for claustrophobic patients
  • Transparent pricing with no hidden contrast charges

Illnesses Diagnosed with Abdomen Lower Thorax CT Scan

  • Appendicitis
  • Diverticulitis
  • Kidney & ureteric stones
  • Hepatic & renal cysts or tumours
  • Abdominal aortic aneurysm (AAA)
  • Pulmonary embolism (lower-lung segments)
  • Lymphadenopathy
  • Bowel obstruction or perforation

Preparing for test

  1. Fasting: 4–6 hours for contrast studies; plain scans may need no fasting.
  2. Hydration: Drink 500 ml water unless instructed otherwise.
  3. Medications: Continue routine medicines; bring a list.
  4. Clothing: Wear metal-free attire or change into provided gowns.

11. Prerequisites

  • Recent serum creatinine report (within 4 weeks) if contrast is planned.
  • Pregnancy test for women of child-bearing age when indicated.
  • Allergy history documentation.

12. Best Time to Take the Scan

  • Morning slots are ideal for contrast studies (better tolerance after overnight fast).
  • Emergency cases: 24×7 availability at Cadabams Diagnostics.

13. Eligibility

  • Adults and children >2 years (paediatric protocols available).
  • BMI <200 kg supported on our scanners.
  • Patients with pacemakers or joint implants are eligible; inform the technologist.

14. Procedure Step-by-Step

  1. Check-in: Confirm ID, consent, and allergy form.
  2. Contrast: Drink oral contrast over 45–60 min or receive IV line.
  3. Positioning: Lie supine, arms above head.
  4. Scan: Hold breath for 10–15 seconds while the table moves.
  5. Observation: 15-minute post-contrast watch for any reactions.
  6. Go-home: Resume normal activities unless sedated.

15. Caution Before Taking the Test

  • Discuss renal function if you have diabetes or hypertension.
  • Discontinue metformin for 48 hours post-IV contrast, per physician advice.
  • Remove metal objects—belts, zippers, piercings.
  • Inform staff about asthma or prior severe allergies.

Test Results

Results and Interpretations

Finding / ObservationDescriptionGeneral Interpretation / Significance
Normal scan No abnormalities detected Indicates healthy organs and no acute pathology
Mild inflammation Slight swelling or thickening of tissues Suggests possible infection or early disease; clinical follow-up recommended
Abnormal massPresence of unusual density or shadowPotential tumor or lesion; further diagnostic tests may be necessary
Kidney stones High-density spots within the kidney or ureterConfirms presence of calculi; may cause pain or obstruction
Enlarged lymph nodesLymph nodes measuring >1 cm in short axis Could indicate infection, inflammation, or malignancy; requires clinical correlation
| Bowel wall thickening| Thickening of the intestinal wall May indicate inflammatory bowel disease, infection or neoplasm; clinical assessment advised

Risks & Limitations

  • Radiation exposure: Roughly equivalent to 6–12 months of natural background radiation.
  • Contrast allergy: Rare (≈0.04 %); inform staff of prior reactions.
  • Kidney considerations: IV contrast may stress compromised kidneys; blood tests may be required.
  • Pregnancy: CT is avoided unless absolutely necessary; alternative scans may be offered.

5. Types of CT ABDOMEN & LOWER THORAX

Type Contrast Purpose
Non-contrast None Kidney stones, trauma
Triple-phase IV Liver lesions, tumour characterisation
CT Enterography Oral + IV Crohn’s disease, small-bowel evaluation
Low-dose CT Optional Screening high-risk patients

FAQs

Is the scan painful?

No. You may feel warmth from contrast or mild bloating from oral prep.

How much radiation will I receive?

≈5–10 mSv, comparable to 1–2 years of natural background exposure; dose-reduction algorithms minimise risk.

Can I drive after the scan?

Yes, unless you took sedatives for claustrophobia.

Will I need another scan soon?

Only if clinically necessary; we follow ALARA (As Low As Reasonably Achievable) principles.

When and how will I get my results?

A specialized radiologist will carefully interpret your scan, and a comprehensive report will typically be available within 24 hours. The report will be sent directly to your referring doctor, who will then schedule a follow-up with you to discuss the results in detail and outline the next steps in your care plan.
