Three-dimensional contrast-enhanced MR angiography of the thoraco-abdominal vessels

With the strategies presented in this article, relevant disease involving the thoraco-abdominal vessels can be well depicted by 3D CEMRA. Aneurysms, dissections, occlusions, congenital lesions, and anatomic anomalies are readily assessed. Time-resolved MRA provides supplemental information in shunts, dissections, aneurysms, and AVMs. Velocity-encoded imaging may help further characterize lesions and may provide useful functional information to grade and monitor the progression of stenotic disease. 3.0T imaging and recent development in multicoil RF technology will further improve the performance of 3D CEMRA in terms of temporal and spatial resolution.
