Comparison of magnetic resonance imaging and ultrasonography in the evaluation of abdominal aortic aneurysms.

摘要: Magnetic resonance imaging (MRI) was used to evaluate abdominal aortic aneurysms in 27 patients. The findings were compared retrospectively with CT, ultrasound (US), and angiography 17 cases prospectively US 10 cases. MRI identified the renal arteries all cases, demonstrated involvement at or above origin of eight patients, showed extension aneurysm into iliac 12 outer dimension aneurysm, diameter residual lumen, length measured easily from MR images. measurements transverse similar for MRI, US. more accurately defined below bifurcation. It is concluded that provides necessary information surveillance preoperative evaluation aneurysms.
