Repaired type A aortic dissection with very slow flow and thrombus (blue arrow) in the false lumen. Top row computed tomography angiography. Middle row 3D uSSFP. Bottom row Peak systolic magnitude (left) and flow (right) images from a phase contrast (PC) cine acquisition with in-plane velocity encoding sensitivity of 150 cm/s show negligible flow in the false lumen (*). Nonetheless, 3D uSSFP acquired with a gradient spoiler factor = 1.0 was able to suppress the blood pool signal in the false lumen, while the dissection flap (red arrow) is well demonstrated. Chronic intraluminal thrombus appears relatively bright with 3D uSSFP, as does mediastinal adenopathy
