Fig. 2From: Feasibility of 3D black-blood variable refocusing angle fast spin echo cardiovascular magnetic resonance for visualization of the whole heart and great vessels in congenital heart diseaseSimulated signal of blood at different velocities (in mm/s) for 3D FSE across the echo train (a). Eight startup echoes were used at the start of the echo train during which no data was collected, and using a centric view ordering scheme the centre of k-space (k0) was acquired at the 9th echo (dashed line). The echo signal at k0 acquisition shows good suppression of velocities higher than 30 mm/s (b)Back to article page
