Dual-phase CT of the liver and pancreas with contrast is a diagnostic imaging technique that involves two sequential scans: an arterial phase and a venous phase. This procedure provides detailed images of the liver and pancreas, allowing for the evaluation of various conditions and abnormalities in these organs.
 
Procedure: During the examination, a contrast agent is injected intravenously. The scan is performed in two phases:
Arterial Phase: Conducted immediately after contrast injection, this phase focuses on visualizing the blood vessels and blood flow within the liver and pancreas.
Venous Phase: Performed a few minutes after the arterial phase, this phase provides images of the liver and pancreas tissues, highlighting any abnormalities or pathological changes.
 
Components of Contrast Agent:
Iodine-Based Compound: Provides enhanced image contrast.
Auxiliary Substances: Stabilizers and solvents.
 
Applications: This dual-phase CT is used for:
Detecting Liver and Pancreatic Tumors: Identifying potential tumors or masses.
Evaluating Biliary Duct Obstructions: Assessing blockages or abnormalities in bile ducts.
Monitoring Chronic Liver Conditions: Such as cirrhosis or liver fibrosis.
Identifying Developmental Anomalies: In the liver or pancreas.
Assessing Traumatic Injuries: To the liver or pancreas.
Evaluating Treatment Effectiveness: For cancers or other diseases of the liver and pancreas.
 
Preparation: For accurate results and safety:
Fast Before Procedure: Do not eat or drink for 4-6 hours before the scan.
Allergy Information: Inform your doctor of any allergies to contrast agents or iodine.
Pregnancy and Breastfeeding: Notify your doctor if you are pregnant or breastfeeding.
Chronic Conditions: Report any chronic diseases like diabetes, kidney, or thyroid disorders.
Remove Metal Objects: Take off all jewelry and metallic items.
 
Procedure Steps:
Initial Scanning: Perform a scan before contrast injection.
Contrast Injection: Administer the contrast agent via an intravenous catheter.
Sequential Scanning: Conduct scans in the arterial and venous phases.
Duration: The procedure is generally quick, lasting about 15-30 minutes.
