Abdominal aortic aneurysm evaluation: Comparison of US, CT, MRI, and angiography

Ultrasonographic measurement of aortic diameter by emergency physicians approximates results obtained by computed tomography

“…They were then expected to measure aortic anterior-posterior diameter with the ultrasound transducer in transverse orientation at the level of the SMA and at a point estimated as 1 cm above the iliac bifurcation. An additional measurement was taken with the transducer in longitudinal orientation between the SMA and bifurcation (2,7,(21)(22)(23). Ultrasonographic measurements were taken from inner wall to inner wall.…”

Comparison of Ultrasonography, Computed Tomography and Magnetic Resonance Imaging With Intraoperative Measurements in the Evaluation of Abdominal Aortic Aneurysms

“…Comparisons between the diagnostic accuracy of different radiological methods for measuring aneurysms have been made in several studies, with very controversial results. 8,9,10 Few authors have compared imaging methods (USG, CCT, HCT, and NMR) with the surgical findings, which is the most reliable standard for such comparative studies.…”

Preoperative hypofibrinogenemia is associated with increased intraoperative bleeding in ruptured abdominal aortic aneurysms

“…33 AAA imaging through US, computed tomography (CT) or magnetic resonance imaging (MRI) has been compared. 85 Ultrasound is not as sensitive as CT and MRI for AAA diagnosis especially in obese patients with proximal aneurysms. In Figure 1 three different techniques for the diagnosis of AAA are illustrated.…”
