Jul 26, 2024 · Pulsation artifact is very common in non-gated CT scans, seen in up to 92% 8. The diameter of the ascending aorta should be measured at multiple levels, making follow-up scans more accurate for comparison 4,5: level of the aortic annulus. level of the aortic sinus. level of the sinotubular junction. mid ascending aorta

May 23, 2013 · Measurements are typically reported at aortic annulus (solid black line), aortic sinuses of Valsalva (solid white line), sinotubular junction (dashed black line), mid ascending aorta (dashed white line), and high ascending aorta (dotted black line).

Oct 9, 2024 · Now I get this lung cancer screening ct scan done and it says as incidental finding my ascending aorta is dialated to 3.9cm. Does this mean it’s grown 1.6 mm in two years or could this be just from different measurement methods?

Jan 13, 2025 · Dilatation of the ascending aorta is a common finding in the elderly but unusual in younger patients. In adults, an ascending aortic diameter greater than 4 cm is considered to indicate dilatation 4.

Mar 20, 2024 · The ascending aorta ascends slightly towards the right of midline where it can be seen as part of the mediastinal outline on a chest radiograph. This should only be the case in the older ectatic or dilated artery.

Apr 25, 2023 · Usually, you'll have an echocardiogram, CT or magnetic resonance angiography (MRA) scan at least six months after your aneurysm is diagnosed. An imaging test also may be done at regular follow-up exams.

Sep 1, 2020 · Although echocardiography has some roles in screening and monitoring the aortic root and ascending aorta, computed tomography and magnetic resonance imaging are necessary for the complete assessment of the thoracic aorta and are often necessary for surveillance.

If your aortic aneurysm was first detected by a CT or CAT scan, it’s important to have another, immediate scan via either MRI or TEE. The reason is that sometimes, the interpretation of a CT reading is overestimated.

Recently, a published study demonstrated that dual source CT scan is as accurate as MRI in documenting TAA diameters in patients with BAV and a stenotic aortic valve which comes to reinforce the role of CT scanning in the diagnosis of TAA dilatation.

Ascending aortic aneurysms (AsAA) remain a silent killer for which timely intervention and surveillance intervals are critical. Despite this, little is known about the follow-up care patients receive after incidental detection of an AsAA. We examined the pattern of surveillance and follow-up care for these high-risk patients.
