Patent ID: 7501821

Claim:
A method for determining the transverse relaxation time T2* in magnetic resonance data, comprising the steps of: detecting a T2* relaxation in a measurement volume of a subject, said measurement volume exhibiting a magnetization while said T2* relaxation is being detected; determining a local magnetic field in said measurement volume by determining a phase curve of said magnetization in said measurement volume for a plurality of predetermined echo times having respectively different time intervals from one another and determining the local magnetic field in the measurement volume from said phase curve, and adapting the interval between respective echo times for at least one point in said measurement volume, to allow determination of said local magnetic field without phase compressions, by selecting said interval between said respective echo times to produce an in-phase condition; and correcting said T2* relaxation time dependent on said local magnetic field, to obtain a correct transverse relaxation time T2* .
