Abstract: A magnetic resonance scanner (12) is configured for thermographic imaging. One or more processors (28) receive (56) thermal image data from the magnetic resonance scanner and reconstruct at least one thermal image in which each voxel includes a measure of temperature change. The one or more processors identify (58) thermally abnormal voxels. A display (44) displays at least one reconstructed image with the identified abnormal thermal locations.

Abstract: 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 B0 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.
