CT Triphasic Abdomen

A CT TRIIPHASIC ABDOMEN is an advanced three-phase computed-tomography study that captures images of your abdominal organs at different times after an IV contrast injection. At Cadabams Diagnostics, we combine cutting-edge 128-slice CT scanners with experienced radiologists to deliver sharp, motion-free images in under 15 minutes. Whether you need to rule out liver lesions or evaluate kidney function, our streamlined process ensures comfort, clarity, and speed.

• Definition: A scan taken in three distinct phases—arterial, venous, and delayed—to trace how contrast flows through blood vessels and organs.
• Technology: Uses low-dose radiation protocols and iterative reconstruction to reduce exposure while preserving image quality.
• Difference: Unlike a routine single-phase CT, the triphasic approach highlights subtle abnormalities in liver, pancreas, kidneys, and major vessels.

1. Liver Triphasic CT – Focus on hepatic masses & vascular anatomy.
2. Renal Triphasic CT – Evaluate kidney tumors, stones, and perfusion.
3. Pancreatic Triphasic CT – Detect islet-cell tumors or pancreatitis complications.
4. Whole-abdomen Triphasic CT – Comprehensive screening in trauma or cancer staging.

• Timing intervals: 25 s (arterial), 60 s (venous), 180 s (delayed).
• Slice thickness: 0.625 mm for isotropic reconstruction.
• Contrast volume: 1.5 ml/kg up to 120 ml, non-ionic iodinated.
• Kilovoltage: 100–120 kVp auto-modulated.
• Hounsfield Unit (HU) thresholds for lesion characterization.

• Characterize indeterminate lesions found on ultrasound.
• Plan surgical or interventional procedures with 3D road-mapping.
• Monitor post-treatment response (TACE, RFA, chemotherapy).
• Detect occult sources of GI bleeding.

• Symptoms prompting the scan
• Unexplained abdominal pain
• Jaundice or abnormal liver-function tests
• Blood in urine or rising creatinine
• High-risk groups
• Chronic hepatitis or cirrhosis patients
• Individuals with a family history of renal or hepatic tumors
• Post-cancer follow-up cases needing precise staging

• High accuracy: >90 % sensitivity for hepatocellular carcinoma detection.
• Single-session imaging: Avoids multiple scans, saving time and money.
• Early detection: Identifies tumors when still resectable.
• Digital sharing: Instant cloud reports for tele-consults.

• Liver: Hepatoma, hemangioma, metastasis, fatty infiltration.
• Kidneys: Renal-cell carcinoma, angiomyolipoma, pyelonephritis.
• Pancreas: Adenocarcinoma, neuroendocrine tumors, pseudocysts.
• Vascular: Portal-vein thrombosis, aneurysms, arteriovenous malformations.

• Fasting: 4–6 hours nil-by-mouth; clear fluids allowed.
• Hydration: Drink 500 ml water the night before to protect kidneys.
• Allergies: Inform staff about iodine, shellfish, or prior contrast reactions.
• Medications: Continue most drugs; hold metformin 48 h post-scan if eGFR <30.
• Clothing: Wear metal-free attire; lockers provided for valuables.

• Recent serum creatinine (<4 weeks old).
• Diabetic profile if on metformin.
• Pregnancy test for women of child-bearing age.
• Signed consent after risk counseling.

• Morning slots preferred for diabetic patients to shorten fasting time.
• Avoid booking during active menstruation if pelvic extension is required.
• Emergency cases accepted 24×7 at Cadabams Diagnostics.

• Adults and children >15 kg.
• eGFR >30 ml/min/1.73 m² (lower values need nephrologist clearance).
• Not advisable in pregnancy unless life-saving; lactating mothers can resume feeding after 24 h.

1. Check-in: Present prescription & ID at front desk.
2. Assessment: Nurse checks vitals, inserts IV cannula.
3. Positioning: Lie supine on CT couch; automatic voice commands guide breathing.
4. Contrast: Warmed Omnipaque 350 mg/ml infused via power injector at 4 ml/s.
5. Scanning: Three short breath-holds (~5 s each) capture the phases.
6. Observation: Monitored for 15 min post-scan for delayed reactions.

• Asthma or severe allergy: Premedication with steroids may be arranged.
• Claustrophobia: Open-bore CT minimizes anxiety; mild sedation on request.
• Kidney disease: Hydration protocol and nephro-protection discussed beforehan

• Contrast reactions (rare): Mild nausea to severe allergy—our staff is ACLS-trained to handle emergencies.
• Radiation exposure: Equivalent to ~6 months of natural background; we use dose-tracking software to keep ALARA.
• Limitations:
• Poor images in patients with significant obesity or metallic implants
• Cannot fully characterize lesions <5 mm without follow-up MRI
