What is the first choice follow up if a AAA is suspected?

Doppler ultrasound is the first-line test when an abdominal aortic aneurysm is suspected because it quickly confirms whether an aneurysm is present, measures its size, and assesses blood flow, all without radiation or contrast. It’s safe, fast, portable, and widely available, so it can be done right away in the emergency department or clinic to establish a diagnosis. Once an aneurysm is confirmed, the size and location guide urgency and next steps; larger or complicated aneurysms are typically evaluated with CT angiography to get detailed anatomy for planning repair. CT provides the most precise detail but involves radiation and contrast and takes more time, so it isn’t the initial test in a stable patient. MRI offers excellent detail but is less practical in acute settings, and X-ray does not reliably detect AAA.
