Description: CT Angiography of the abdomen is a diagnostic imaging technique that uses computer tomography (CT) and contrast material to visualize the blood vessels within the abdominal cavity. This procedure enables healthcare providers to assess the condition of the blood vessels, detect aneurysms, blockages, stenoses, and other vascular abnormalities.
 
Applications: CT angiography of the abdomen is used for:
Assessing Abdominal Aortic Aneurysms: Identifying aneurysms in the abdominal aorta.
Detecting Vascular Stenoses and Occlusions: Evaluating narrowing or blockages in blood vessels.
Identifying Congenital Vascular Abnormalities: Diagnosing structural anomalies in blood vessels.
Evaluating Organ Blood Supply: Understanding the blood flow to abdominal organs.
Planning Surgical Procedures: Assisting in the preparation for surgical interventions by mapping vascular anatomy.
 
Vascular Structures: Key blood vessels in the abdomen include:
Aorta: The main artery supplying blood to the abdominal organs.
Celiac Trunk: Supplies blood to the stomach, liver, spleen, and pancreas.
Superior Mesenteric Artery: Provides blood to the small intestine and part of the large intestine.
 
Indications for CT Angiography of the Abdomen: The procedure may be recommended for:
Evaluating the Abdominal Aorta: To detect aneurysms or occlusive diseases.
Diagnosing Renal Artery Conditions: Such as stenosis or obstruction.
Assessing Blood Supply to Abdominal Organs: Including the liver, spleen, and other organs.
Investigating Trauma or Inflammatory Conditions: Related to blood vessels.
Planning Surgical Interventions: Requiring detailed vascular assessment.
 
Preparation: For optimal results and safety:
Dietary Restrictions: Avoid eating and drinking for 6-8 hours before the procedure.
Allergy Information: Inform your doctor of any known allergies to contrast agents or other medications.
Pregnancy Status: Notify your doctor if you are pregnant or suspect you might be.
Kidney Function: Report any kidney issues to your doctor as special precautions may be needed.
Remove Metal Objects: Remove all jewelry and metallic items that may interfere with the images.
 
Procedure Steps:
Positioning: The patient lies on a CT scanner table.
Contrast Injection: A contrast medium is administered through an intravenous catheter.
Scanning: The patient remains still and may be asked to hold their breath briefly while the CT scanner rotates to capture detailed images.
Duration: The procedure typically takes 30-60 minutes.
