  4. 12. Acquisition strategies for fat/water separated MRI

    Author : Henric Rydén; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : This thesis focuses on new ways to more efficiently acquire the signal for fat/water separated MRI, also known as Dixon methods. In paper I, the concept of dual bandwidths was introduced to improve SNR efficiency by removing dead times in a spin echo PROPELLER sequence. READ MORE
