1. An MR imaging pulse sequence and reconstruction method that comprises the steps of:

  • identifying a first imaging volume;

    providing a first coil element sensitive to the first imaging volume identifying a second imaging volume;

    providing a second coil element sensitive to the second imaging volume;

    setting the shim currents to optimize the field homogeneity over the first imaging volume;

    using a first spectral-spatial RF pulse to selectively invert the magnetintion from adipose tissue in the first imaging volume;

    setting the shim currents to optimize the field homogeneity over the second imaging volume;

    using a second spectral-spatial RE pulse to selectively invert the magnetization from adipose tissue in the second imaging volume;

    exciting the magnetization in both imaging volumes simultaneously;

    acquiring the MR data simultaneously from the first and second imaging volumes;

    reconstructing the MR signal from the first imaging volume;

    reconstructing the MR signal from the second imaging volume; and

    using the SENSE algorithm in the slice direction.
