Abstract
In a magnetic resonance imaging method, inner radial readout lines (100, 200, 300, 400) in an inner portion (102, 202, 302, 402) of k-space are acquired using a first readout magnetic field gradient profile (120, 220, 320, 420). Outer radial readout lines (104, 204, 304, 404) in an outer portion (106, 206, 306, 406) of k-space disposed substantially outside of the inner portion of k-space are acquired using a second readout magnetic field gradient profile (124, 224, 324, 424) different from the first readout magnetic field gradient profile. The acquired inner and outer radial readout lines are reconstructed to produce a reconstructed image.
