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
- Fasting: 4–6 hours for contrast studies; plain scans may need no fasting.
- Hydration: Drink 500 ml water unless instructed otherwise.
- Medications: Continue routine medicines; bring a list.
- 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
- Check-in: Confirm ID, consent, and allergy form.
- Contrast: Drink oral contrast over 45–60 min or receive IV line.
- Positioning: Lie supine, arms above head.
- Scan: Hold breath for 10–15 seconds while the table moves.
- Observation: 15-minute post-contrast watch for any reactions.
- 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 / Observation | Description | General 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 mass | Presence of unusual density or shadow | Potential tumor or lesion; further diagnostic tests may be necessary |
| Kidney stones | High-density spots within the kidney or ureter | Confirms presence of calculi; may cause pain or obstruction |
| Enlarged lymph nodes | Lymph 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.
