Fig. 1From: Radial-based acquisition strategies for pre-procedural non-contrast cardiovascular magnetic resonance angiography of the pulmonary veinsComparison of 6-mm thick maximum intensity projection (MIPs) from coronal navigator-gated free-breathing 3D balanced steady state free precession (bSSFP) using a spatially non-selective radiofrequency (RF) excitation with Cartesian sampling (left) and radial stack-of-stars (SOS) sampling (right). Similar echo train length, spatial resolution and scan time were used for the two acquisitions; an ipat factor of 3 was used for the Cartesian acquisition. With radial imaging, ghost artifacts within the cardiac chambers and pulmonary veins are eliminated, while vessel and diaphragm sharpness are greatly improvedBack to article page
