CT angiography of the pelvic arteries

CT Angiography of the Pelvic Arteries

We remind you that independent interpretation of the results is unacceptable, the information provided below is for reference purposes only.

CT angiography of the pelvic arteries is a non-invasive imaging technique that uses computed tomography (CT) and intravenous contrast material to visualize the blood vessels supplying the pelvic region. This procedure provides detailed images of the arterial anatomy, helping to diagnose and evaluate various conditions affecting the pelvic arteries.

Procedure and Purpose

During the CT angiography of the pelvic arteries, a contrast agent is injected into a vein, typically in the arm or hand. As the contrast material circulates through the bloodstream, it enhances the visibility of the pelvic arteries on the CT images. The CT scanner captures multiple cross-sectional images of the pelvic region, allowing for the reconstruction of detailed 3D images of the arteries.

This procedure is often used to evaluate the following conditions:

• Atherosclerotic disease or narrowing of the pelvic arteries
• Aneurysms or dilations of the pelvic arteries
• Arterial occlusions or blockages
• Congenital abnormalities of the pelvic arteries
• Evaluation of blood supply to organs in the pelvic region

CT angiography of the pelvic arteries provides valuable information for the diagnosis and treatment planning of various vascular disorders in the pelvic region, helping to ensure proper blood flow and prevent potential complications.

The Role of CT Angiography of the Pelvic Arteries

CT angiography of the pelvic arteries is a diagnostic imaging technique used to evaluate the blood vessels in the pelvic region. It provides detailed information about the anatomy and potential abnormalities or blockages in the arteries supplying the pelvic organs, such as the reproductive organs, bladder, and lower digestive tract.

Indications for CT Angiography of the Pelvic Arteries

CT angiography of the pelvic arteries may be ordered in various clinical situations, including:

• Evaluation of pelvic pain or discomfort: CT angiography can help identify the underlying cause of pelvic pain, such as arterial occlusions or aneurysms.
• Assessment of vascular abnormalities: This imaging technique can detect congenital or acquired vascular malformations, such as arteriovenous malformations or fistulas.
• Evaluation of pelvic trauma: In cases of pelvic injuries, CT angiography can help assess the extent of damage to the pelvic arteries and guide treatment.
• Preoperative planning: Prior to certain pelvic surgeries or interventions, CT angiography may be performed to provide a detailed map of the pelvic vasculature, aiding in surgical planning and minimizing potential complications.
• Monitoring of treatment response: For conditions such as pelvic arterial occlusive disease or aneurysms, CT angiography can be used to evaluate the effectiveness of treatments and monitor disease progression or regression.

Preparation for the CT Angiography of the Pelvic Arteries Procedure

Preparing for a CT angiography of the pelvic arteries involves several steps to ensure the accuracy and safety of the procedure:

• Fasting: You may need to avoid eating or drinking for several hours before the exam, as instructed by your healthcare provider.
• Medication: Inform your doctor about any medications you are taking, as some may need to be adjusted or discontinued temporarily.
• Contrast agent: This procedure involves the use of a contrast agent, which is injected intravenously to enhance the visibility of the blood vessels. You will need to discuss any allergies or medical conditions that may preclude the use of contrast agents.
• Kidney function: If you have a history of kidney problems or impaired kidney function, additional precautions may be necessary to protect your kidneys from potential adverse effects of the contrast agent.
• Pregnancy: If you are pregnant or suspect you may be pregnant, inform your healthcare provider, as alternative imaging methods may be recommended to minimize radiation exposure.

The CT Angiography of the Pelvic Arteries Procedure

During the procedure, you will lie on the CT scanner table, and an intravenous line will be inserted into your arm or hand to administer the contrast agent. The CT scanner will rotate around your body, capturing detailed images of the pelvic arteries while the contrast agent highlights the blood vessels. You may be asked to hold your breath for short periods during the scan.

Calculation and Purpose

CT Angiography of the Pelvic Arteries is a medical imaging technique that uses computed tomography (CT) and intravenous contrast material to visualize the blood vessels supplying the pelvic region. It is often performed as part of a comprehensive evaluation of the aorta and its branches or to assess specific conditions affecting the pelvic arteries. This diagnostic test provides detailed images of the anatomy and potential abnormalities or blockages in the arteries supplying the pelvic organs and lower extremities.

IMPORTANT!

It is crucial to remember that the information provided in this section is not intended for self-diagnosis or treatment. If you experience any pain or exacerbation of a condition, it is essential to consult a doctor for diagnostic tests and proper treatment. Only a qualified specialist can make an accurate diagnosis and determine the appropriate treatment. To ensure the most accurate and consistent evaluation of test results, it is recommended to have them performed at the same laboratory. This is because different laboratories may use varying methods and units of measurement for similar tests.
