Mr imaging using shared information among images with different contrast

摘要

A method of magnetic resonance imaging includes performing a first magnetic resonance scan sequence which saves a data store and performing a second magnetic resonance scan sequence which uses a data store from the first magnetic resonance scan sequence. A magnet (10) generates a B field in an examination region (12) a gradient coil system (14 22) creates magnetic gradients in the examination region and an RF system (16 18 20) induces resonance in and receives resonance signals from a subject in the examination region. One or more processors (30) are programmed to perform a magnetic resonance pre scan sequence to generate pre scan information perform a first sequence to generate first sequence data refine the pre scan information with the first sequence data perform a second imaging sequence to generate second sequence data. Further the second sequence data is either reconstructed using the refined pre scan information or performed using the refined pre scan sequence information.
