摘要：A system and method for multi-spectral MR imaging near metal include acomputer programmed to calculate an MR pulse sequence comprising a plurality of RF
pulses configured to excite spins in an imaging object and comprising a plurality ofvolume selection gradients and determine a plurality of distinct offset frequency values.For each respective determined offset frequency value, the computer is programmed toexecute the MR pulse sequence having a central transmit frequency and a central receivefrequency of the MR pulse sequence set to the respective determined offset frequencyvalue. The computer is also programmed to acquire a three-dimensional (3D) MR data setfor each MR pulse sequence execution and generate a composite image based on datafrom each of the acquired 3D MR data sets.
