Black blood steady state free precession magnetic resonance imaging

摘要

In the imaging process, in order to maintain a steady magnetic resonance excited in the imaging area, maintenance radio frequency periodic pulses α, -α is applied. In selected periods between maintenance radio frequency pulses, read 66 of the imaging data from the imaging area is performed. During the period selected other maintenance between radio frequency pulses, blood signal suppression sequence 62, 62 'spatially selective is performed. Blood signal suppression sequence, suppress the blood signal suppression in a region different from the imaging area. Blood signal suppression sequence, with a moment applied magnetic field gradient of substantially zero order.
