What is a Triple Phase CT Scan?
A Triple Phase CT Scan is a specialized contrast-enhanced imaging technique used to assess liver conditions, abdominal organs, and blood flow abnormalities. This scan captures images during three different phases (arterial, portal venous, and delayed) after contrast injection, providing a detailed view of tumors, liver function, and vascular structures.

When is a Triple Phase CT Scan Recommended?

• Liver tumors (Hepatocellular carcinoma, metastases, hemangiomas, etc.)

• Cirrhosis and liver fibrosis assessment

• Portal vein thrombosis or vascular abnormalities

• Pancreatic or abdominal tumors

• Evaluation before liver surgery or transplantation

• Detection of bile duct obstructions, infections, or liver cysts

How is a Triple Phase CT Scan Performed?

1. Preparation:

   • The patient may need to fast for 4–6 hours before the scan.

   • A contrast dye (iodine-based) is injected into a vein for clear visualization.

   • The patient must inform the doctor about allergies or kidney issues before the procedure.

2. Triple Phase Imaging:

   • The patient lies on a CT scan table, which moves through the scanner.

   • Images are taken in three phases:

     • Arterial Phase: Captures images immediately after contrast injection, highlighting arteries and detecting tumors.

     • Portal Venous Phase: Captures images 30–40 seconds later, showing blood flow in the liver and detecting abnormalities.

     • Delayed Phase: Captures images after 2–5 minutes, helping assess slow-enhancing lesions or fibrosis.

3. Completion & Recovery:

   • The scan typically takes 15–30 minutes.

   • Patients can resume normal activities immediately, unless advised otherwise.

   • Drinking plenty of water helps flush out the contrast dye.

Benefits of a Triple Phase CT Scan

• High-precision imaging for accurate diagnosis

• Early detection of liver cancer, tumors, and vascular issues

• Non-invasive and fast procedure

• Guides treatment decisions for liver diseases and surgeries
