Abdominal aortic aneurysms (AAA) are potentially life-threatening conditions that often develop silently without showing obvious symptoms. These aneurysms, which occur when the abdominal aorta — the large blood vessel that supplies blood to the abdomen, pelvis, and legs — becomes weakened and bulges, can rupture if left undetected. Ruptured aneurysms can lead to severe internal bleeding and death if not treated promptly. Early detection of abdominal aneurysms is critical for preventing life-threatening outcomes, and one of the most effective diagnostic tools for identifying this condition is the CT scan (computed tomography).

At Great Lakes Medical Imaging (GLMI), we provide advanced CT scan services to help detect abdominal aneurysms early, offering Buffalo residents and patients in Western New York the highest standard of care. In this article, we will explore the benefits of using CT scans for diagnosing abdominal aneurysms, the advantages of early detection, and how CT imaging can guide treatment decisions to prevent complications.

What Is an Abdominal Aortic Aneurysm (AAA)?

An abdominal aortic aneurysm (AAA) is a condition where the wall of the aorta — the major blood vessel in the abdomen — weakens and begins to bulge. If the aneurysm grows too large or bursts, it can cause life-threatening internal bleeding. Many people with abdominal aneurysms experience no symptoms, which is why this condition is often called a “silent killer.”

However, as the aneurysm grows, it can become painful, leading to discomfort or pain in the abdomen, lower back, or groin. Some common risk factors for AAA include:

• Age: Those over the age of 65 are at higher risk.

• Family history: A family history of aneurysms increases your risk.

• Smoking: Smoking significantly raises the risk of aneurysms.

• High blood pressure: Hypertension can weaken the aortic wall, leading to aneurysms.

While the condition can remain asymptomatic for years, if it ruptures, it requires emergency medical attention.

How CT Scans Are Used to Diagnose Abdominal Aneurysms

A CT scan uses X-rays to create detailed cross-sectional images of the body. For diagnosing an abdominal aneurysm, CT scans are often the imaging method of choice due to their high resolution and ability to clearly visualize the aorta and surrounding structures.

CT scans provide critical information for diagnosing AAA, including:

• Size and location of the aneurysm

• Presence of any rupture or dissection

• Extent of damage to the aorta and surrounding blood vessels

• Whether the aneurysm is growing over time

With a CT scan, radiologists can create a 3D reconstruction of the aorta, allowing healthcare providers to assess the aneurysm in three dimensions and make informed decisions about treatment.

The Benefits of Using CT Scans for Diagnosing Abdominal Aneurysms

1. Early Detection of Abdominal Aneurysms

One of the most significant benefits of using CT scans is the ability to detect abdominal aneurysms early, often before they become symptomatic. In the early stages, AAAs are often asymptomatic and may not cause pain, making it difficult for patients to identify the condition without imaging.

• Why It’s Important: Early detection allows doctors to monitor the aneurysm's size and growth rate, ensuring that appropriate steps are taken to prevent rupture.

GLMI's Advanced CT Imaging enables us to assess abdominal aneurysms quickly and accurately, allowing your healthcare provider to begin monitoring or treatment before complications arise.

2. High Accuracy and Detail

CT scans provide highly detailed images that are far more precise than traditional X-rays or ultrasound. The level of detail helps doctors identify small or early aneurysms that might otherwise go undetected. For patients at risk of AAA due to factors such as age, smoking, or family history, a CT scan provides a non-invasive, reliable method of checking for aneurysms.

• Why It’s Important: A precise diagnosis is critical in determining whether the aneurysm requires active monitoring, medication, or surgical intervention.

At GLMI, our state-of-the-art CT imaging provides detailed, accurate images of the abdominal aorta to ensure that your condition is correctly diagnosed.

3. Monitoring Growth Over Time

Abdominal aneurysms can grow slowly over time, so regular imaging is essential for monitoring the size and progression of the aneurysm. CT scans are often used in follow-up exams to assess whether an aneurysm is increasing in size and to determine if intervention is necessary.

• Why It’s Important: Monitoring the aneurysm’s growth is key to deciding when surgery or other interventions are needed. If an aneurysm grows too large (usually over 5.5 cm in diameter), the risk of rupture significantly increases, and surgical intervention may be required.

At GLMI, we can perform follow-up CT scans to track any changes in the size of the aneurysm, allowing for timely action.

4. Guiding Treatment Decisions

For larger abdominal aneurysms or those that are symptomatic, a CT scan helps determine the best course of treatment. It can identify the location and size of the aneurysm, which are critical factors in deciding whether surgery (e.g., endovascular aneurysm repair (EVAR) or open surgery) is required.

• Why It’s Important: Accurate imaging is essential for selecting the right surgical or medical treatment, ensuring the best possible outcomes.

GLMI’s CT scans provide invaluable information that helps guide decisions about whether surgical repair, medication, or continued monitoring is the appropriate course of action.

5. Non-Invasive and Fast

A CT scan is a non-invasive procedure that provides fast results. For patients experiencing symptoms or concerns about abdominal aneurysms, CT imaging is a quick and effective way to get the necessary information without the need for invasive procedures.

• Why It’s Important: The ability to quickly diagnose and monitor aneurysms means fewer delays in treatment, reducing the risk of complications.

At GLMI, our advanced CT technology provides timely, non-invasive imaging, giving you fast results and peace of mind.
