Claims
- 1. A method for view-angle tilt magnetic resonance imaging of an object having a localized magnetic susceptibility variation, the method comprising the steps of:
a) applying to the object an excitation RF pulse simultaneous with a first field gradient; b) applying to the object a refocusing RF pulse simultaneous with a second field gradient; c) applying to the object a tilted readout gradient tilted at an angle selected to provide incomplete removal of the image distortion produced by the magnetic susceptibility variation; whereby magnetic susceptibility contrast is provided in the region of the magnetic susceptibility variation.
- 2. The method of claim 1 further comprising the step of adjusting the tilt angle to provide a desired amount of magnetic susceptibility contrast.
- 3. The method of claim 1 wherein additional refocusing RF pulses, second field gradients, and tilted readout gradients are applied to comprise a rapid acquisition and relaxation enhancement sequence.
